Hi guys I am new to Subaru I work on Honda a lot I do reprogramming for the cl7 and cl9 with k engine series but recently I start working on Subaru I have an ej20R twin turbo the head stamps are RH B2 LH B2 with yellow injectors and orange fuel rails .I convert it to a single turbo , now my problem is sourcing an ecu , I know I need an Sti v3/4 ecu ,, but the one I brought has an AVCS and my engine doesn’t have one anyone can help me regarding the ecu code or part number and harness is it possible to use the v3/4 harness ? Thanks
