I got tunercat working on my laptop with benchtop harness and 12 volt invertor. I cant figure out how to change my tuning for my 94 LT1 with 4l60E. Its going in a 68 Camaro. This is what i am doing:

1) Cats removal

2) headers

3) EGR removal

4) AIR pump removal

5) 2200-2400 stall convertor

6) Charcoal canister removal

7) lower primary fan turn on to 160 (for Mark 8 fan)

8) change gear ratio (I figured that one out)

9) LT4 knock module

Any help would be appreciated

 

Go into the switch table and just turn off all that stuff that you won't be using. There's a table for the fan - set that to whatever you want. Some of the other stuff is more subtle and no one is going to tell you exactly how to adjust for it. Obviously, you can adjust shift points and mixture at WOT, but if you don't know how to do that stuff, then sarch some of the LT1 runing tutorials or get someone else to do it for you, or take it to a dyno tuner.
