PCM and Stall question
PCM and Stall question So two quick questions, the tune i have in the 94 Z28 is tuned for a 503 cam, we just put a motor in and she has LT's, Underdrive, AC delete and of course a 2800-3200 stall. I was wondering how rich or how bad the tune is going to be cause of the 503 tune that was tuned for the same exact except mid's. Also, is the vats in the PCM? Say I use a PCM from another car, will it work or will it not even start cause of the VATS?
Second, the stall in the car starts to move at around 1,500-2k. I don't remember it being like that in the formula, it would just move it as soon as i put my foot down. I was wondering if it needs more transmission fluid or maybe check the stall out and see if there is a problem with it or what?
All help is appreciated! Thanks!!

Motor we put in has a stock cam. He is also wondering if the resistance reading for the VATS is in the PCM or not. We have what I think is a stock PCM sitting here, didn't know if it would work for the time being if we sent the 503 tuned PCM out for a retune.

I'd be checking the fluid before driving it anywhere. Thats how they act if there low enough on fluid.

ok yea the pcm is for the same exact year and same options? if not I would not but thats just me. Running the 503 PCM could cause wash down and at worst cause a hydro lock on the rings, would not even idel on that. if you have check the oil and if it smells like gas change it. As for the trans um It sounds like what robs said in that there may not be enough fluid. If you know its full then It sounds like something is binding up. If you want a trans guy to look at it or talk to them, Monster transmissions is right there in spring hill. I bought my 4l60e from them. Curt is the head tech there. On a side not I live just down the road in Holiday south of NPR. lol small world.
What brand of stall is it?
I belive the VATS is in the BCM not 100% on that. you should be able to bypass it in the steering column.

Car is running fine on the 503 tune, but yeah I figure it would run rich if anything? I wouldn't think the options would matter in regards to the PCM, maybe we will send the Formula's PCM out for the reflash then instead of the mystery PCM that we assume has a factory tune in it.
We should have a Pasco/Hernando meet, the one guy from Monster was actually trying to set one up at Beef O Brady's, there really wasn't too much interest though I guess.....

since you bought it from them I would call or stop by and talk to curt (if he is still there) He might be able to point you in the right direction. I had a problem with the trans I got from them and took moths to figure out. I actually took the car up there and had curt drive it to figure it out. Ended up being a defective sunshell. It had a fracture in it that would cause 1st gear to not engage all the way.
