Hey guys playing around with my 95RMS tune and I go it pretty dialed in, but the IAC counts are really pretty low, as in it is almost like someone, i.e. previous owner turned the throttle stop screw a bit, from previous knowledge and my other car, idle should be between 30 and 40 IAC counts, but my RMS is at about 10 at idle. I think that it may be causing a BLM split in these areas, as in the left BLM is always about 6 higher than the right, I have read that the IAC can cause this, but just curious on your guys thoughts. once the IAC follower reached about 40 or so the BLMS even out. Now there is no exhaust leaks or anything like that, and I know that individual fuel trim multiplier can cause this as well. As well as if you put the trans in gear the engine will bog, as well as any load on the motor. I am going to go out and play with it a little today, just curious on your guys thoughts for this.
For the speedo it is weird, the gauge is 2 miles an hour high and the scan tool gauge in free scan or datamaster is about 2 mph low, 225/70/15 tires with 2.56 gear. I have used the tool in tuner cat, which is based on an excel spreadsheet that I got from Alex and Anthony at PCMperformance, but the values between the two don't match. When I did the tune with the tuner cat speedo calc, the speedo was 5 mph off, but with spreadsheet it was only 2 mph off, any thoughts on this?
