58MM TB Tuning Question
I just ordered LT1 Edit so I can program my computer. I saw in another post that if you have a 58MM throttle body that you have to go into the Transmission tables and do something. Can anyone help me out? I ordered the "expert" edition of LT1 Edit.
Basically I am going to start slow with the programming and then eventually take it to a dyno and go all out. For now I want to do some basic stuff like:
adjusting the idle, setting the engine size (383 now) etc. Please look at my sig for the mods that I have.
Thanks!
Tim

Re: 58MM TB Tuning Question (I_HATE_Mustangs)
Ok, I found a file out here: http://www.bfranker.badz28.com/LT1Edit/LT1files.htm
It was a file for a Z28 with a 58mm and modified trans tables. I copied the trans tables and loaded them into my car.
Result (so far): shifts are much firmer at WOT yet silky smooth with regular driving. I have to tell you that I was skeptical about copying the table because he jumped from 90si to 112psi on WOT. I only bumped mine to 110 just to test the waters. Does anyone know if this is too extreme? Hopefully I won't blow up my tranny :nono:
Can someone please chime in?

Good site.. I was able to find a stock '94 auto vette with 3.07 gears on there (.bin). I'm hoping it hasn't been modified. My computer has already been modified, and I'd like to try modifying my already modified one.. as well as starting from scratch to see how well I can get it setup.
