Do I need an s5 AFM for my s5 j-spec turbo swap? My car is an s4 turbo 2. Am still using the s4 harness/ecu to. Currently, the car starts, runs smooth above 1,500 rpm and stalls if I let off the gas pedal. I can keep the car running below 1,500 rpm but it runs really really rich. After doing the un-flooding procedure, it does the same thing. What do you think?

no the s4 one is the only one calibrated correctly for a s4 ecu... i was just wondering if that might of been the problem... do you have any vacume leaks?? do u have a boost gauge whats your vacume when your tring to get it to idle as low as u can??

ohh yeah does the car drive ok? besides no iulding like could u drive around the block??

TPS
if it is too rich, maybe it isnt fuel cutting like it should

Yes, the car does drive down the street but the boost guage doesn't work. the vaccume line comming from it is not hooked up.

been following this a bit,good info ..at least elimination of the obvious can get to the heart of the problem..i was wonderin about the AFM also..so I quickly side-step(thanks guys)and let the original thread starter get his answer..

Well, the TPS is fine, and the AFM is an S4. I just don't have the vaccume on the boost sensor hooked up.
