Started Programing about a month or so ago. Started with "easy F-body Tuning" and adjusted Trans to shift and speedometer. Simple stuff, have been trying to get on this forum for weeks "mostly my fault - started with adding old E-mail" but have been messing with it trying to learn myself from reading forums from here and other sites. Have done small AFR and Timing adjustments. Messed with trans shift pressures and points a good bit but have gone back and forth with it.

So it runs good, strong but think i should be getting more out of it in higher RPM's.
Trans feels real good but would like to calm 1<2 shift a little more on lighter throttle.

Biggest problem at this point is somewhere in trans programing I have lost the 1st gear command for coming to stops. Doesn't down shift coming to stop, touch throttle and commands first gear and is perfect till next stop. NO SLIPPAGE at all, just not commanding the shift. I can't figure out why. Have made numerus adjustments since and can't figure parameter that I might have changed.

Will try to down load Bin I'm running currently.

Another Question I have is in EEHACK I cant read certain things data-logging. Like, for me the biggest is the Trans info; which is what I really want to learn for my small Tranny Shop "ZT Performance".

Should I have left stock (96 Buick ECM) in instead of switching to new(95 Impala SS)
What difference would it make? Pro's and Con's of each?
Truthfully I tried doing this yrs ago on my 95 Z28 and was having communication problems which I found out my nemesis back then and at beginning of this try with the Buick came down to Laptop I was using... have new one now. And as any older FART I am not very computer literate.
But at time of starting this process with Buick I didn't do my research again, after all I did that yrs ago, and I didn't realize the huge steps that has been made with these programs for OBD2 systems and first thing i did was get me a 95 ECM. If the OBD2 is a better way to go I will gladly go back. Haven't really looked into any of the OBD2 programing because of what I'm Running right now and trying to learn this has been a ordeal for me but I am studying and learning I think, but as in anything I might be Learning bad practices. But I will be looking into OBD2 programing so I can get into changing programs for tranny's I build.

Thankyou in advanced.
And thanks to Stevo and everyone else that has made all this possible. It was one of Stevo's posts in a F-Body forum that made me look into this yrs ago for my 95 Z28
