Ok here is the Deal I got a 1996 Nissan 200sx with a BB DET swap... Of course using stock DE ECU and Harness, 370's stock maf. Fellow forum member is selling a JWT for a b14 with this specs ( JWT ECU(3bar, 370cc, turbo program, stock maf, 9.5:1 compression(stock de). Now I don't have a FPR so its not set at 3 bar and as you all know the BB has 8.5 compression. Can I use this JWT ecu? so is the 3 bar and compression an issue?
