s5 n/a auto ECU for spark only?
I am not sure what all the ECU requires to run normally and not on limp mode.
I want to use an S5 N/A auto tranny computer for SPARK ONLY. I want to use it on an S4 turbo engine. Do you guys think this will work?

The timing is supposed to be retarded under boost via the boost sensor. So....probably wouldnt be able to do that unless your willing to run without boost timing retard. but keep in mind most people trick the ecu into only thinking that there is 6psi anyways with an fcd so the amount of timing retard that actually takes place?.....who knows?
