Watched it with dual widebands yesterday and it is around 14.7 afrs most of the time in normal driving with one bank going slighly lean, its close but the main problem is the refusal to idle down when the clutch is put in until it comes to a stop. I think its in the iac steps as they show only 5 in the step down counts from 60 mph to 0 with the final step at 30. Hopefull I will get TunerPro set up on my non serial laptop tomorrow so I can watch what calibration cells are active. Finally got a decent *.adx file so I can link it to the actual *.bin the motor is running on. The *.xdf file is complete hack from the an ORIGINAL GM calibration document that I have had for a while. I give credit for the *.xdf hack to Tod P who had most of it done when I sent him the document. He also did the *.ads file which has been converted to *.adx to work with the most recient version of TunerPro. I ain't no pro but I been around long enough (1997) to know what works.

PS I have one of the first MegaSquirts so know quite a bit about that too.

OK! I have no idea what he just said sad on my part. Glad there are brothers that do

Tyler,

Why don't you download and send me your bin file? I'll take look at it if you'd like.

Where can one access the ADX? I have one that worked with my 89 L98 that I re-worked for the 90 Z but would like to see what I might have missed

Tyler sounds like Your Z drives just fine that is the way the factory did it to resolve other issues.

If you want this done right you need to take/bring the whole car,otherwise you will have other issues if you only make this one adjustment to the chip program.

Trust me i know this issue very well, i run Stage III cams in my 350ci
