    circle dirt track 2.2l ecotech

    I'd like to tune my 2004 chevy cavalier for a hornet series we run on an 3/8 mile track clay oval, and tips on where to start, what to change?

    Not really much you can change.

    Turn off any check engine codes. Lower the enable settings for power enrichment so it comes in faster and trying to command an air fuel around 12.3ish or so. I highly suggest running 91+ octane because it's going to be nothing but full throttle.

    That's pretty much all I did on the 2 different Cavaliers I'd done for a guy. Did the codes, PE stuff, maybe added 1-2 degrees of timing and turned off the VATS for him. His grandsons drove those cars for a few seasons last I heard.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
