    I have all the programs and I think I have the libraries for it. MED stopped by today so I took a look at what I could find out on GM's side. I can down load all the files still from GM.
    Some of the aftermarket programing program I have work with OBD I and MEMCAL's. Hmmmmmmmmm

    I just have not seen the light.
    I just don't think I should jump into a market that has programmers already.

    MED talked me into looking at least. Hmmmmmmmmmmmmmmmm

    I have everything and I can do a lot with them with no effort.

    The leaded tunes are EXPORTS, but not all exports are leaded. They have a more aggressive tune to them.

    I am at home so I can dig through all the old programs that I have.


    BTW ever seen a Northstar with a manual? Allante?

    Talking Re: 93 to 95 Northstar Tuning

    OK I have some new pictures.

    The first is a snapshot of a WOT from a dead stop with a stock DHS program
    look at how much the PCM allows for max power/torque on this run



    This WOT run is at a dead stop with a tuned PCM
    99% torque Hmmmmmmmmmmmmmm
    of course this is mine!!!!

    AJ,

    That's great news. I want what you have. I hope other OBD-1 owners are interested too. Thanks for the ride in the "Turd".

    Re: 93 to 95 Northstar Tuning

    AJ,
    In my testing of my 98 STS motor with 95 pcm, what I thought was 2nd gear starts was really the torque
    management killing the power. It seems to be related to a timer off the brake circuit cause I can downshift
    from 3/2/1 and then go wot WITHOUT touching brakes and I get a good launch but if you hold brakes and try to launch in either D or 1st, you get torque management and a poor, low power, launch.

    If you can fix this, I will be your 1st customer and be very gratefull!!

    Aj I agree making a buck is a good thing, The problem your have is the same as everone else has selling a product.

    Everyone is looking for number's Dyno stuff to back up your charts and personal work. Can you do better than FastChips? Have you Dynoed your own Northstar? I don't mean to question your work but I think if your going to sell a product you got to back it up with some real number. I think thats what happened with the guy that have Fastchips also.

    What I want to know is the same question I have been asking. Can you build a total package? IE CHRFAB has some nice parts I want to use so I will ask you the same question I ask Wester can you tune for the cams head work and so on?

    I have not seen any thing good from chrfab except the valve covers. Don't take that the wrong way I am sure that they have done great work. $1200 bill for head work that I could do blind folded. Wait I saw a blind guy porting heads once. I had an ECU on a sand rail that was programed twice and took a third time to make it right.

    Let me ask you
    If your PCM is limiting you to XXX ft lbs torque and you build the motor to make 5000 ft lbs how much torque will the PCM allow?

    next question
    If you make 100 hp at 2000 rpm and 275hp at 6000 stock Y engine SAE report
    If I can make 130 to 150 hp at 2000 and 275 at 6000 does it make more power?

    next
    If you make 80hp @ 200 and 292 @ 6300 Stock 9 engine SAE report
    If I make 130hp to 150 hp @ 2000 and 275hp @ 6300 does mine make less power?

    If a quarter mile calculator says bert's aka Highline cady's DHS is producing 320HP out of a VIN Y 275 hp motor on my tune is it correct?

    So do we have any stock 03 STS or DTS dyno runs?
    I will put $500 down saying that my 00 to 03 program will produce more power. It may not be peak, it may not be HP but it will make more power or torque. $500 says it will. I think a VIN would be the best way to tell.

    Yes I can get Cams.
