1st Gen Legacy/SVX SpeedyEFI Plug and Play ECU

PLEASE DOUBLE CHECK THE MODEL LIST BELOW!!!

Here we have our 1st Gen Legacy/SVX SpeedyEFI Plug and Play ECU kit! That's right! This ECU is suitable for both Legacy's, as well as SVX's! The pinouts are nearly the same, with only a few differing pins. The small black cards pictured are what determine whether this ECU is for a Legacy or an SVX. They essentially rewire the differing pins to match the application. These ECUs will come in a custom designed, 3D printed case that fits in the factory mounting location, and plugs into the factory wiring. We've included screw terminals for the O2 controller and launch control connections, spare inputs, and more! Any pin not being used is available as a breakout on the board. As always, all of our kits come pre-wired for boost control and flex fuel. These ECUs are capable of running an SVX, and can run a Turbo or N/A Legacy, with a coil pack or COP, with a stock engine or an H6 swap.

As a legal disclaimer, this product is intended for off-road/race use only. We do not provide any form of tuning aside from a base map. A base map is solely intended to allow you to start the car. This will need tuned via TunerStudio. Please note, this ECU will eliminate the OBD2 system, which means your vehicle will not pass emissions in states/counties that require testing. Use at your own risk!

This ECU is good for the following USDM models only:

1990-1994 Legacy N/A

1990-1994 Legacy Turbo

1992-1996 SVX (OBD1 only)

If your vehicle is not in the list, this ECU will not work in your vehicle. The H6 option is higher priced as it will also require an engine harness adapter. If swapping a different H4 into your vehicle, select the H6 option, and email us with info on which engine you're using so we can build the appropriate engine harness adapter. This ECU works for non VVT/VVL engines only. Current build time is 1-2 months. As we continue to work towards building our inventory, build times will steadily get shorter. If you have any questions, feel free to reach out!

P.S.-Better photos will be uploaded soon!
