I have a friend that just bought a '93 LT1 Camaro and was wondering if I could tune a '93... I have never even looked at a '93 PCM, but tuning is similar if I have the right equip..

Anyway, my question is, on '93 is the PCM flashable like 94-95s or is it a chip that must be physically removed and placed in a burner?
If flashable, is the same ALDL connector as the '94 used?

Thanks

 

1993s have ECMs and uses replaceable chips, not flash programming like 1994 and up.

 

As Shoebox pointed out, its an ECM because it only controls the Engine, not the Powertrain.

The ALDL connector is a 12-pin OBD-I connector, same as a 94.

The engine control strategy is virtually identical to the 94 and later PCM's, except for the fact it runs in speed-density, rather than mass-air, and uses batch-fired injectors, not sequential. It is also unique in the it is the last year you can flash the DTC codes on the SES light, by shorting the correct ALDL pins.

And its got a removable "chip", as Shoebox pointed out.

 

Thx, sounds like its basically the same as the TPI chip burning I used to do.
Do either of you know if the ALDL connector is the same as for a '90-'92 TPI motor for scanning?

 

Same AFAIK.

 

2QUICK6 let us know how you make out!

 

Will do, but I have no idea when he wants me to try anything with his car, he's not even sure he's going to keep the motor that in it...maybe a month or 2 knowing him.
