what changes(tunercat)

i have been playing with tunercat and pcmcomm. i am using the $EE for my obd1 94 vette. i have a few questions to throw out to see if i can get some clarification.
1. when i set my closed loop temps(min temp for closed loop) way up my car will start cold or warm . if i set them where they should be it will not start when warm.

2. in pcmcomm i get "learn disabled" even when in closed loop.

3. what would cause me to have to double the maf tables to get my car to run. i have looked at several others who run the same set up as me. and their maf tables are about 1/2 what mine are set for. injector constant is correct and fuel pressure is set correctly.

still looking for light at the end of the tunnel.

as for question #3, but my understanding is the higher the MAF, the more fuel going in because the computer thinks more air is going in, are you running rich? Or is it running correctly?

Its impossible for your car to start warm... What it will do is go into close loop after it has reached the temp you set.

You should get learn disabled only when it WOT.. if you have learned disable something is not set up correctly...
