Hi
With lumpy cams as I did here:
http://www.hptuners.com/forum/showth...ight=ford+idle
was quite good. But with turbo in addition it was not so easy, everything has to be on spot, otherwise idle are getting crazy.
Finally I have very good idle and drivability, but...
Transition from dashpot to rpm control while stopping. Sometimes this transition is fast and car slowing down at 1k rpm with clutch on and when stopped slowing down to 800. But sometimes he jacks RPM's to 1200-1300 when stopped and after it goes to 800. Idle air is on spot, idle air integrator is in +-0.3 range , idle comes quite quick to 1000, also when driving. No bouncing or so.
If I make that he will not jack up rpms on stop, then when driving RPM's fall off too much with clutch on.
I tried to modify speed when it comes from dashpot to idle control, but when it's high, drivability sucks, but idle while stopping are ideal.
It has DBX MAF in blow thru config, close to GT500 TB.
I have no such problems on same setup but without cams, even exact calibration ID.
Any ideas where to look?
