court916 Posted January 8 Report Share Posted January 8 I've been brewing up ideas on running Flex Fuel/e85 in my ej22E, but I don't have knowledge on the ecu type, and I'd like to keep the factory harness in one piece for diag reasons, and I'd like to keep the OEM functionality of the car since it's a daily driver. If anyone could direct me towards the best plug and play link ecu for the application, I'd be grateful Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 8 Report Share Posted January 8 I suspect this car would want a "V4" ecu, check that your existing ecu has the same 3 plug header as this one: https://dealers.linkecu.com/WRX4X_2 Quote Link to comment Share on other sites More sharing options...
