The OpenPort 2.0 is Tactrix's newest tuning tool hardware that is capable of communicating with most OBDII compliant vehicles using a standard J2534 interface. Combined with the EcuFlash software, the OpenPort 2.0 is capable of reflashing a large number of newer Subaru and Mitsubishi vehicles, and support for other cars is in progress.
We include a USB cable with each OpenPort, which is all the hardware you'll need unless you have one of the few vehicles that require a separate reflash adapter. For Subaru you'll only need a reflash adapter for the 2001 through 2005 WRX, but not STi, unless you're working on an early non USDM STi in which case you made need one of our WRX adapters. No other Subaru vehicles require reflash adapters including Forester, Baja, Legacy, or naturally aspirated Impreza models. For Mitsubishi, you'll need the adapter for most pre CAN vehicles which include the 5-9 Evo. Choose the adapter you need from the 'Reflash Adapters' drop down list on the right side of this page.
Designed, manufactured, assembled, and tested in San Francisco, USA
Tactrix Openport 3.0 tuning cables will be released Q2 of 2025!
The factory location of the ACD pump has been known to cause premature failure of the pump due to its direct contact with the elements. The plate inside of the pump becomes corroded and causes the pump to lose pressure and turn off. This kit allows you to move it into the trunk and keep your pump out of the elements.
Only available with black powder-coated aluminum brackets and carpeted cover
Only Fits 08-15 Evolution X
CNC laser cut from .063 aluminum
Stainless steel hardware
350psi hoses (3) with anodized aluminum fittings
System bleeding required after install
This is the Premium kit which includes 48" nylon braided rubber hoses. This kit will allow relocation to the trunk with abrasion-resistant hoses. Hose connections will be made to hard lines near the subframe and gas tank. This will eliminate the short sections of hard line.
Fuel Cut Defenser - Experiencing fuel cut with your boosted Protege? This kit will allow you to run increased boost without hitting the dreaded "fuel cut".
Instructions:
PLEASE NOTE- The FCD unit will raise your vehicles fuel cut psi, which is a safety feature designed into the ECU mapping to protect the vehicle from over boosting and causing engine damage. Installation of this unit removes the safety cap and will allow you to overboost your engine. Installation is recommended only by those qualified to alter the vehicle from it's stock form. With this in mind, these instructions are written to give only enough information for an experienced tuner/installer to understand.
The FCD unit hooks between the MAF signal wire and a ground and requires a boost source to switch it on and off. There are two ways to tap the MAF line- one is at the ECU pin 88 and the other is at the MAF sensor pin B- either will work. Tap one wire from the FCD unit to the signal line (the FCD is not polarized, so either wire will work) and the other wire to a good ground. It is preferred that the signal wires be soldered. Once the wiring is completed, run an 1/8" hose from a vacuum pressure source to the fitting on the FCD.
The FCD utilizes a boost switch to activate it which is adjustable. It should be good where it is set, but you may notice that if you go WOT in say 4th gear at 2000 rpms and slowly lug it through the powerband, it may lean out when hits the preset psi and the switch kicks in, or some cars may feel a quick, slight stumble when it kicks in at higher RPM's- this is normal and you can adjust it to raise the psi at which it kicks in to help smooth it out- I can not preset them to work perfectly for every car (come in at the exact time your specific car would need it). Adjustment is easy- if you look at the FCD, you will see an allen screw which requires a 2mm allen wrench- turning the screw clockwise will cause the FCD to kick in at higher boost levels. Note- this does not affect the PSI/airflow at which fuel cut will occur- it will only increase the PSI at which the switch is mechanically activated. If you tighten this screw too much, the switch may not kick on until after the factory fuel cut threshold, which cause the vehicle to fuel cut- so it is recommended you leave it at the factory setting.
DISCLAIMER- THE BUYER IS RESPONSIBLE FOR PROPER INSTALLATION OF THIS PRODUCT. ALTERING ANY VEHICLE FROM IT'S STOCK CONFIGURATION CAN BE DANGEROUS AND/OR CAUSE FAILURE. IF YOU FEEL YOU ARE UNABLE TO SAFELY COMPLETE THIS INSTALLATION, YOU MAY WANT TO CONSIDER BRINGING THE VEHICLE TO A PROFESSIONAL OR CONTACT US FOR FURTHER ASSISTANCE.

This aluminum valve cover will not melt like the plastic ones, and will allow the valve cover to Powder Coated!
This is the OEM valve cover on from the 2008 Evo X which Mitsubishi later changed to plastic in order to cut costs. It is compatible with all Evo Xs.
Includes Valve Cover Gasket as well as spark plug gaskets.
These are brand new valve covers, and if you decide to have us powder coat them, we DO NOT sandblast them like some other shops do. They are simply prepped and then powder coated.
We also recommend one of our spark covers to keep heat away from your coil packs, and to give the valve cover a nice, complete look.
Please note that valve covers are powder coated to order, so please allow time for this.
Optionally, you can replace your crusty old valve cover bolts with out Valve Cover Bolt Kit!
Powder coated valve covers are not returnable or refundable, as they are considered to be custom.
If you're making over 400whp, you'll want these upgraded pulleys to keep your serpentine belt intact! The Mitsubishi OEM pulleys are made from plastic and will permanently distort with big power, causing your belt to walk and shred time and time again. Don't leave yourself stranded and constantly in need of a new belt. Fix the problem by installing these steel pulleys.
Note: The pulley that goes onto the OEM belt tensioner will require the use of the provided washers to ensure proper the clearance for the pulley to fit.
XXL firewall heat shield helps prevent heat and fire damage.
Benefits and features include:
New XXL version designed to fit with large turbo setups, even those with large external wastegates such as the Full Race and ETS turbo kits.
Designed to help prevent any firewall fires
Constructed from stainless steel with a mirror finish
TIG Welded for superior strength
Install in minutes thanks to outstanding fitment
Protects critical components such as wiring, ABS system, AC system, and more
Please note: The XXL version requires you to remove two small 6mm studs on the firewall, in addition to a square rubber grommet. Installation guide to come. With some turbo kits, trimming of the bottom left of the shield by a few inches may be necessary for downpipe clearance. The last image will show the measurements required to trim the shield for the ETS Turbo kit.
Instructions to trim this are as follows:
From the horizontal break, measure down on the left side of the piece 7" and place a dot.
From the horizontal break, measure down on the first bend 5" and place a dot.
From the horizontal break, measure down on the second bend 7" and place a dot.
From the previous dot, measure to the left 1.5" and place a dot.
Connect all of the dots from left to right as shown in the photo.
Cut on the line you created. This will allow space for the ETS downpipe to clear while still protecting the lines behind the shield.
If you plan on running this shield with a large turbo kit, it may be necessary to install this before the turbo kit.

How it works
Purchase this item. In the comments field, list the year and trim of your Evo X, along with every modification to the car which could effect performance. This includes, but is not limited to engine modifications, wheels, tires, intake, exhaust, weight reduction, fuel system, etc.
Depending on the extent of your modifications, you may be required to pay additional fees for your tune. Items such as upgraded fuel systems, turbos, larger MAF housings, and so on will require much more time and calibration, hence, added cost.
You will be emailed a starter tune. You will be asked to download this tune to your ECU and log certain parameters in certain conditions.
Email us the logs, and you will receive an updated tune. The process of logging and updating your tune will continue until the tune is complete. An entry level tune will have a maximum of 15 versions for the above price.
Note: The tunes are the intellectual property of SpeedCircuit, and may not be shared with anyone without written consent. Furthermore, it is the responsibility of the owner to ensure that the car is mechanically sound. SpeedCircuit is not liable for any damages that may occur to your car. E-Tunes are done at your risk.
Requirements
Laptop Computer
Tactrix OpenPort 2.0 Cable w/ EvoScan OR a Cobb Accessport
If you wish to use the ECUFlash method of tuning but do not have a Tactrix 2.0 cable, you can purchase one here.
A knowledge and understanding of how a car works mechanically, in order to be able to track down potential issues.
If it is suspected that your car has mechanical issues, you will be asked to address them or have a professional do so. If you do not look into suspected mechanical issues, we will not be able to resume tuning your car until you do. It is not the responsibility of the tuner to diagnose any mechanical issues.
Recommended
An Innovate or AEM Wideband O2 gauge with logging cable (required for all non-stock turbo tunes). If logging with a serial cable, we recommend a plugable USB to serial adapter which is available on amazon. If you are going to log via an analog connection, which is the only current way to log via Cobb AccessPort, see here for wiring instructions.
A boost gauge
Det cans to hear potential knock with.
What to log
Wideband (only if you have a wideband O2 gauge installed)
Throttle Position (TPS)
RPM
Load
Boost
Baro (if required by boost)
Knocksum
Timing Advance (ignition)
Active WGDC Correction
Odd Clutch Slip Speed (if tuning SST)
You may be asked to log more items as the tune progresses.
Please be sure to only do one full throttle pull per log. The pull should be from 3200-7000rpm unless specified otherwise.
Warning: E-Tuning requires that the driver of the car be aware of potential issues that may arise during tuning. This may include the car running lean, overboosting, detonating, or any other mechanical issues. If something doesn't feel right, take your foot off the throttle immediately and end the pull. SpeedCircuit, LLC is not responsible for any damages your car may incur! If you are not comfortable with this, please visit us for an in-person tune.
Expect an average of one new tune file per week. This will vary based on both our schedule and how quickly you can provide logs for the most recent update to your tune. There may be times where we may be unavailable, so on occasion there may be weeks where we are not available for e-tuning.
If you're not familiar with how to set up your car or computer to log or flash tunes on your car, or you need help with diagnostics, please check the Phone Support option.
Note: Once an initial base map has been sent to you, there are no refunds.
Titanium Steel spark plug cover for the Evo X, Ralliart, and Lancer.
Designed for optimum fitment with the oem aluminum valve cover, this spark cover not only looks great, but isolates the coil packs from the heat of the exhaust manifold and turbo. Bolts on in seconds. Includes stainless steel hardware.
CAD Designed and 3D Printed ABS Plastic gauge pod for your Evo X.
This 52mm pod can be added to the left side of your OEM gauge surround. It requires you to drill three small mounting holes to affix the pod to the stock plastics, as well as one larger hole to run the wiring through.
With these pods there is no more waiting for months to get a custom pod made only to have it crack.
Replace your fragile, rusted stock valve cover bolts with this beautiful stainless steel bolt kit! Includes all stainless bolts and cup washers in a variety of colors.
18 x Colored Cups
18 x Long Bolts
16 x Threaded Standoffs (two long bolts do not use a threaded standoff)
These manifolds flow well and are built to last with zero failures to date!
P.E.P. manifolds are 304SS throughout! Never worry about rust or failed coatings.
Utilizes 1/2″ flanges 4 mm thick walls to ensure strength with a low weight
Positions the turbo in the stock location and is flanged for all T2 turbos (including but not limited to the stock turbo)
All Manifolds include:
An O2 bung in the collector for the stock primary O2 Sensor
An EGR fitting which is positioned so that you can reuse your stock EGR tube, but the tube may need some slight adjustments in position for a perfect fit.
8 x black oxide socket cap bolts to replace the factory manifold bolts or optional upgraded stainless bolts or ARP stainless studs and nuts
Installation tips:
Use Anti-seize on all exhaust hardware
Use optional studs wherever possible
Cut the short end of an allen wrench down to about 0.75″ in total length so it can fit into some of the tighter spaces (such as the center bolts)
Ball end allen wrenches will be very helpful throughout the install.
The M20 threads on the EGR fitting can be very difficult to start especially if the alignment isn’t perfect. To make things easier loosen the EGR tube support bracket near the water neck and the nut at the intake manifold. With these loose, it becomes very simple to get the EGR fitting started at the exhaust manifold. Snug everything down once all threads are started.
Stainless steel heat shield for your exhaust cam sensor. Designed to protect your cam sensor from damage, especially when running tubular manifolds where the runner is very close to the sensor. Fits any manifold we've tried so far, even the Full Race!
CAD Designed and 3D Printed ABS Plastic gauge pod for your Evo X.
This 52mm pod can be added to the left side of your OEM gauge surround. It requires you to drill three small mounting holes to affix the pod to the stock plastics, as well as one larger hole to run the wiring through.
With these pods there is no more waiting for months to get a custom pod made only to have it crack.
The SpeedCircuit Hotpipe (Upper Intercooler Pipe) is a single piece 2.5" mandrel bent stainless steel pipe (instead of cheap steel that some competitors use to save money). Rather than slimming down the diameter halfway through the pipe like the factory part, our part remains at 2.5" the whole length of the pipe!
Benefits and features of this pipe include:
Improved throttle response
Small power gain
No more stock hotpipe expanding and popping off under boost
Smoother power at the top of the RPM range
Engraved SpeedCircuit logo
Replacement of stock rubber hose which allows you to mount BOV flanges and other accessories and bungs.
T-Bolt clamps for a superior clamping strength.
A show-quality piece to set your engine bay apart from the crowd.
A part that will last the lifetime of the car.
Reinforced silicone hose couplers
Additional options include:
Weld-on BOV flanges for Greddy Type S/RS and HKS SSQ-V
Specialty Powder Coating - You can also choose to do multiple types of finishes.
For example, you could do a polished finish, and on top we can do a black chrome powder coat over it which will tint the polished pipe black. We also have wrinkle and high temp powder coats available as well. Many options are available for finishing, so feel free to ask us about your custom idea!
The SpeedCircuit Automated Super Sport will automatically make your Evo X MR or SE start up with the SST transmission in Super Sport Mode. SST cars which are making significantly more than factory torque should always be run in Super Sport Mode, due to it's increased clamping pressure. Failure to do so will result in excess clutch slippage and short clutch life.
Avoid the hassle of manually putting your car into Super Sport Mode! The factory transmission mode switch will still retain all functionality and will allow you to choose Sport and Normal modes if desired.
Compatibility: This device is made for the Evo X MR and Evo X SE. It will also work with a Lancer Ralliart that has been converted to have Super Sport mode.
Tired of your lower coolant hose and thermostat outlet always getting in the way of your hopes for a nice big downpipe or intercooler piping? Finally, we have your solution.
This kit contains a purpose built silicon hose and straight water outlet neck to route things safely out of the way.
Our wiring trays are 2-3/4" deeper than the original trays available from Exomotive, for a total of 5" deep. This is the maximum tray depth you can have before running into fitment issues. If you plan on putting a lot into your wiring tray, especially if you're using an ECU which is taller than the Miata ECU, this is a must have.
Our trays are laser cut and bent by a computer controlled bender. The lid is included, as will free shipping within the lower 48 states!
After listening to customer suggestions and with help from Dino at SpeedCircuit, SSP has come up with the most comprehensive solution for replacing the oem plastic under panel currently available. Not only did they address the issue regarding the high shipping costs by making this a two piece unit, but they have also managed to incorporate a front jack point location. All this while maintaining the structural integrity and level of protection you would expect from a SSP Under Panel.
Specs:
14.0 lbs total weight!!
6061 Billet ALUMINUM CONSTRUCTION (2.2mm thick)
Powder Coated (Black ONLY)
Oil filter/Oil Drain plug access panels
All New Front Jack Point Location
All New 2 Piece Construction for lower shipping costs
Form meets function with these track tested fenders for your Exocet! #deathmachine tested and approved!
These are made to order, so expect a 2-4 week lead time on average.
Specs and Info:
The mounts are made from 1/2" steel rod with plate steel flanges. They are fully bolt-on, front and rear
The mounts are suspension mounted, and move with the wheel
This kit can accommodate anything from a +25 offset wheel with 205mm tire on them all the way to a 275+ mm tire with a negative offset. For more information on fitment, see our fitment list below.
The fenders pictured are 11.5" wide, which were an optional upgrade from the standard 9.5" wide fender. Neither of these sizes are available anymore. They have been replaced by 8.5" and 10" options, to better suit most people's needs.
The fenders are 1/8" thick aluminum
By default, they will cover a stock NA/NB Miata tire diameter of 22.7". This will work well for a variety of sizes, for example a 245/40/15. To check your tire diameter, you can either check with your tire manufacturer, or use this calculator for an estimate.
f your wheel diameter is significantly different from the stock 22.7" diameter, you may want to use the DIY option, which will allow you to customize your bracket height. This will require welding and a lot of time to set up properly.
Please watch the video below for installation instructions:
Fitment List:
While we cannot guarantee fitment with this kit and the unlimited combinations of wheels, tires, spacers, and suspension, we will try to occasionally update this list of known examples regarding fitment. If the brackets do not fit your wheel setup, it can mostly likely be fixed by using a spacer and extended wheel studs. Alternately, you can return the kit, but you will be subject to a restocking fee.
Modification is required to the rear bracket in order to fit an NA miata donor. The bracket must be ground down to fit.
Fits (YMMV):
Japan Racing JR19 wheels, 15x10.5 ET-32, Hoosier A7 275/35/15, front and rear shock spacers - Plenty of clearance to the bottom of the fender and to the bracket.
Team Dynamics wheels, 15x8 ET25 with 10mm spacers, 205/50/15 tires
JNC 003 wheels, 15x9 ET0,245/x/15 with 5mm spacer - clears fine, spacer was required to clear rear brake calipers
OZ wheels, 16x7 ET36 with 25mm spacer in the rear and a smaller spacer in front, 2015/x/16 Hoosier R7 tires
215/40/17 tires are a close fit
Does not fit:
Custom wheels, 15x11 ET0, 295/35/15 - The inside of the tires rub the fender brackets. They should clear with a 15mm spacer.
6UL wheels, 15x9 ET12 - The inside of the tires rub the fender brackets. They should clear with a 15mm spacer.
SpeedCircuit OTS Tune for bolt on cars, running stock injectors, and pump gas.
**NOTE** This is NOT a custom tune. This is our proprietary canned tune that we feel provides the best bang for your buck if you're looking for a bit more oomph out of your car, but can't necessarily go for a full custom tune. If you do choose our OTS tune, you will be able to upgrade to a custom tune for a small fee.
For all of our customers that have been asking for a cheaper and quicker solution, this is it! We all know that "other" OTS solutions don't offer the safety, power, or reliability that something more "custom" does, but the price is hard to ignore. What if there was option that could give you a good bit more power, without the cost of a full tune? You now have it with the SpeedCircuit OTS Tune! If you plan on staying stock turbo and just going with a FBO while saving money for a full tune this is for you.
Note: The tunes are the intellectual property of SpeedCircuit, and may not be shared with anyone without written consent. Furthermore, it is the responsibility of the owner to ensure that the car is mechanically sound. SpeedCircuit is not liable for any damages that may occur to your car. This is done at your risk. Also, no two cars are exactly the same. If the OTS tune does not run optimally on your car, you may be required to upgrade to an e-tune for better results.
Note: Once an OTS tune been sent to you, there are no refunds.
3″ Downpipe to replace the stock “S” and “J” pipes.
Order your PEP MSP Downpipe kit today!
PEP downpipes are 304SS throughout which includes the casting, tube, flange, and flex.
Replaces the “S” and “J” pipes with a one piece design
Very robust design and construction
Bolts to the midpipe in the stock location using a generic 2 bolt flange.
4.5 mm wall thickness on the casting so it is very strong!
The only required modification to the car is removal of the tab on the AC compressor.
All PEP downpipes include the following additional parts:
Hardware Kit – Includes a 3″ exhaust gasket and 5 x 8x1.25x25mm bolts.
Thermostat Spacer – this is an aluminum 1/2″ thick spacer to space out the water neck. Allows the use of the stock lower radiator hose and comes with gaskets and hardware. Alternately, you can choose to upgrade to the SpeedCircuit Thermostat Outlet kit at a discounted price. This is a more elegant solution, and includes a new silicon radiator hose.
The pipe is a tight fit and has the minimum clearance to just about anything and everything. Installing this downpipe with a stock midpipe can be done, but is not recommended as it will most likely leak and can be overly difficult to install.
Pipes are made to order and are generally welded and generally shipped the Saturday after the order is placed.
Installation tips
Remove the radiator and thermostat housing – this isn’t 100% required, but will make the job much simpler
Remove the manifold, turbo, and stock s and j pipes as a unit. Leave the oil return fitting attached to the main bearing support plate – to accomplish this remove the flexible line at either the turbo or fitting.
Remove the s and j pipes from the turbo and also remove the top two turbo to downpipe studs.
Install the PEP downpipe to the turbo – use the provided socket cap bolts and spacers in the upper bolt locations. The hole locations on the downpipe do not allow it to wiggle on the turbo. They will allow it to bolt on, but do not allow for any movement.
Reinstall the manifold, turbo, and downpipe combo and the associated oil and coolant lines.
Install the thermostat spacer. Use the provided gaskets and hardware to ensure a leak free connection
Attach the midpipe using the provided gasket and hardware. In extremely rare cases, there may be leaks at the downpipe to midpipe connection. Should you experience this it is useful to loosen up the rest of the flanges throughout the exhaust and tighten things from the front to the back. This will eliminate some stress that can exist when the downpipe and midpipe are not perfectly aligned and will take care of leaks.
Reinstall the radiator, intercooler, pipes, and hoses.
Take a gentle test drive to ensure that everything is tip top. This pipe flows much more air than stock and depending on the routing of your vacuum system you may experience boost spikes. This is a function of the turbo building boost faster than the signal is telling the wastegate to open. Rerouting of the vacuum lines can easily solve the problem if you experience it. Also be sure to make sure that the swing valve isn't contacting the downpipe. If it is, you may need to port the downpipe inlet to make room.
