    CASTOR TROY has #1
    I have done a few for myself, but he has #1 and #2.
    #2 did not start, But that was why I sent 2.
    I only have my 99 VIN Y Powered Fiero to play with. I needed a VIN 9 to try a different program.

    We will have some result on this in a week or so. True numbers from the track

    I am at a loss. I thought it was because of K29 RPO. I am running a K29 in my Fiero. The PCM I sent that did not start. Does it have a white sticker on it? I would like to know the 4 letters on it. example: CHTS, CPYK, CABY.

    Would this thread include '98 Aurora?

    I bought a ECU from ebay that's from a '99 Aurora; says it fits 96-99 Aurrora, 96 Deville, 97-99 Deville, 96-99 Seville, and 96-99 Eldo

    Tag on unit:

    I am taking a step back and just doing the 00+ and 98 and 99 Seville's.
    The one 96 eldo ate too much of my time. I am going to personally install it this weekend.
    You stated that you want to do many mods to your car. I think after you get it all done I should work on a program. You talked about injector changes, T-body. I think that after you are done I should run the #s for the different injectors.

    I need a PCM #16214848
    I am running short on them. I had some, but killed two, sent two out (NO PAY & NO RETURN ON THE SECOND ONE). I have two currently, but they are spoken for. The last two I purchased ran $50 each.

    This PCM fits 96 to 99 Northstar's and Old's Aurora

    I am working on some new programs. The ones done are great. The next step are going to be a PCM that I would not suggest running for more than a few hours at a time. It will foul the plugs out, but it makes loads of power.
