What can be changed/adjusted on a 95GT AODE?
I know about the AODE line pressure, turn the fan on at a lower temp, tip in retard, A/F ratio, and I'm sure there's more I forgtten to list.

What's everyone had done during their session? :D Thanx, :D
 
A/F and timing at idle, cold start, part throttle and WOT. Idle speed, rev limiter, 02 transport delay, EGR, thermactor pump, part throttle and WOT shift points, auto trans gear ratio and converter lock. Adaptive learning, chroniometric items, coasting fuel shut off, dashpot, fan control, fuel injector, MAF curve, MAF voltage limits, ISC functions, BP values, open/closed loop control, crank fuel and a bunch of other things - and for each of the items I mentioned there are a TON of prameters to adjust. Modern ECUs (even not so modern like '95's) are really sophisticated.
 
You "can" adjust just about everything that the computer controls.

However, you the things listed are the most common..

AFR and Idle RPM for Driveability and smoothness.

EGR/Smog pump on/off depending if they are still on the car.

Fan settings

TRanny line pressures and shift points for AODE

Injector size if you change the injectors and not your MAM calibration.

Spark tables/Timing.

Those are the main goodies.

How much should a tune cost, about? I just set up an appointment today for the 27th to have mine SCT tuned with a two position chip for $700. Sounds high to me, but then again I know nothing about tuning and everything in my area is expensive. Sorry to kinda jack the thread.
