s5 efi on s4 ???
i searched and found nothing, if you know where i can get info on this send me that way if not than, what is invloved in switching the efi, putting the s5 (two tps's..better flow of air) intake on the s4 motor? i have a safcII and read it works better with s5 because of the narrow range of the s4 or the pessure sensor or something? i just bought a complete s5 intake for 25.00$ minus the injectors
do you have to use the s5 afm? get a s5 ecu? please help thanks

No, you cannot use the Kouki NA ECU unless you use the matching main engine harness.
The harnesses / ECU cannot swap due to the different pin alignments.
You can swap the intake manifolds, but keep all the other stuff (AFM, TPS, ECU, harness, fuel injectors) original.
It's a myth that the Kouki AFM flows better - it might look like that but that hasn't been proven yet.
