that's funny. on the first tune, it's barely making more than some S54s are putting down N/A.

Retuned an earlier AASC Z3 coupe we did. Still 100% stock motor, original headgasket on 2.8L. Added 80lb injectors and e85. Same ~12.5psi boost level.
Tuned a random E46 M3, has headers, stock airbox, stock plenum, etc.

Generally speaking A cammed, M50 manifold, headers, nice Exhaust S52 will max stock MAF at around ~6400. Ive seen the occasional non cammed one also max MAF.

Originally posted by Joe Stock View PostCould it be that 4.89V is the highest voltage set in the MAF scaling from the factory? Some Ford EEC computers only go up to 4.7V in the MAF transfer function even though the MAF can output all the way to 5V. If airflow pushes the output voltage higher than 4.7v, the EEC does weird things too. Most, if not all, real performance tunes for them have transfers that go to 5v with more data points for finer tuning. I'm not sure if the same could be done in the BMW system. Just a thought.
Originally posted by The Dark Side of Will View PostGM MAF's output a frequency proportional to airflow, giving them *FAR* better resolution and range than a 0-5V signal... switch to that system?
