would it work to put a s4 t2 ecu on an s4 n/a?

diffrent boost sensors would throw the ecu off.

im just wondering if they use the same wiring harness

they use the same ECU PLUGS, i am running a t2 ecu on the NA harness



how ever there are a few wires that differ between NA and T2, being the t2 knocksensor, and a couple emisisions control devices, and twin scroll.... not entirly sure which emission things those are..... but if you get the ecu wiring diagram from the factory service manuala nd compair the wires u will know exactly which ones im talkin about.



doing fullemissions/rats nest removal, removal twin scroll removal, and running no knock sensor i didnt have to change any wires at the ECU.



i must note if u are using t2 manifolds and sensors, u will have to extend the BAC and tps wires, as the bac is on the oposite side on the NA, and the tps wouldnt quite reach....
