    GM - cheapest way to delete emissions codes and VATS

    7.9.10 The PCM may be reprogramed to eliminate anti-theft/PATS/VATS as well as to eliminate emissions
    controls such as rear O2 sensors, EGR, Evap, etc. Performance parameters of the tune such as ignition
    and fuel maps may not be altered.
    Eventually, I planning on leveraging the new allowance to permanently remove emissions/nuisance codes and delete VATS, and then have a usable check engine light.

    What's the cheapest/safest way to achieve this?

    That works for GM? Find a tuner and have him remove it, I'd find it impossible to believe they wouldn't do it for far less than $400. There's no thought involved, he'd be done in all of 10 minutes. I have the software to do it to LS1s.

    I guess I could, but then I'd have to put the car on a trailer and tow it there.

    Had a brainfart and should've thought to get it done at the dyno day...

    Maybe the PST guys can do it for cheap at Cresson...

    Should work as long as its 96-newer. I'm sure you could find someone to do it for you but it might be challenging finding someone with a computer that has that vehicles software on it.

    Yeah, I neglected to mention it is in fact an OBDII setup...

    Anything LT1 tuning wise is few and far between. Best bet is to mail the pcm off.
    Expect to pay $100 plus.

    I'll ask Sean the LT1 Whisperer to chime in. I think he used these guys for his LT1 test stand PCM.

    Our OBDII/CAN controller is read-only right now - well other than clearing ad hoc codes that is.
    Depending on when "eventually" is for you we can probably help you there. Unlike Cadillac I don't think GM put that stuff behind a gateway so I think we can get to it - if there is a gateway, that'll be more work but doable. L
    Let's talk at Cresson...I probably won't have time to hack it that weekend but this is something we plan to address near term.

    $75

    *Edit* I really am estatic about this new rule. My check engine light came on sitting in grid before R1 at MSRH. Took it somewhat easy shortshifting and whatnot. Post race, pulled codes, both banks lean, found a vaccuum cap had popped off. With the old 'constant on' CEL, I'm positive I'd have ignored it at least til the end of the weekend and caused some damage. Already blown up one LT1 too many.
