Is it possible to have an automatic eprom in a 6 speed car and still have it run? It is a 92 LT1 vette, and watching a scan of it, the computer is telling the car to idle at 650 rpm, which is correct for an automatic car, but mine is a 6 speed. I am having some weird idle issues and running rich issues and wonder if this might be ppart of the problem. I thought all 6 speed cars were programmed to idle at 800? I know my 96Z was set to 800.

 

When an auto computer went in my 6 speed car.......... reverse was locked out and I could only go in 1st and 4th The lockouts are pcm controlled so don't do it

 

Depends on the year. Not sure with OBD-I & OBD-II units, but the 93 Fbodies only needed a 6-speed chip from GM to replace the auto one...

 

mine is obd1 and would be the same as a 93Z with the removable chip.
i am not looking to put an auto chip in my car, just wondering if it had one in it because the computer is programmed to idle at 650.

 

Good point...... Do the 93s even have skip shift and reverse lockout???

 

I actually had a guy load an auto program into my 96z and noticed the same problems that Hootiez28 had. however, the vette uses a ZF transmission which has a reverse lockout on the gearshfit lever, not in the transmission.

 

Anyone else????
