Does anyone know how interchangeable the ECU's are? (N350,N351,N352,N353) I've seen some people say they should all work. I have a bad N353 currently, but was going to swap in a N351. Just wanted some verification this will work fine. Thanks.

 

theres only 2 wiring harnesses for s5, turbo and non, so all the ecu's plug in.



n350 is a CA coupe

n351 is a FED coupe

n352 is a CA vert

n353 is a federal vert.
