    some of the OS on the 411 were used for the s10. do i need to start out with a 4.3 03 tune or build of the 2.2 or flash a camaro tune?

    Do you have emission laws that say the VIN must match?

    Because in reality the VIN does not need to be correct for anything to make the engine run. I am pretty much positive that you couldn't put a S10 vin number onto a LS1 computer, not with HP Tuners anyway.

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

    We do have emission laws here in NC which I believe the OP is from. Depending on the year they do hook up and look, that being said the VIN will need to match.

    EFI Live can also change VIN. You can do all your tune in HP tuners, and when you are done, just have someone change VIN with EFI live, (you can do it with the 2 way tools.) You'll want to change it back if you need to do more tuning so you don't piss of HP Tuners.

    I can do whatever with the vin#. Just let me know. No need searching anyone out. I'm right here! I can make the v8 file and have the correct vin. No problem.
    Thanks,

    If you have the right cable VIN changing software is free.
