I recently put a new cam in my camaro, had some light headwork done, and put headers on and I bought tunercat to tune it up. The only problem is that I do not really know what I need to change. I have played around with the program and have done a lot of research on it, but have not really found any good information about what to change and how to change it. Any help would be VERY appreciated. Thank you.

 

No one?

 

Year and Engine might help..

 

To start with, you should get a wide band O2 meter and see what the fuel mixture is at different load and RPM conditions before changing anything. In most cases the only thing you will need to do is to make changes for the WOT (open loop) state, the part throttle stuff will probably self adjust.

 

It is a 1994 LT1 5.7 liter. It has a 268 grind cam I think from comp cams. The problem with an O2 meter is that they are pretty expensive from what little I have looked for them.
