    03 Bonneville tune?

    Does anyone have a 03 Bonneville stock tune?

    A friend of mine wants to see the DFCO settings. I don't have HPT, so I would need some screen shots.

    He hates how the lack of DFCO is on this car and wonders what the settings are like.

    Thanks!

    i don't have any late model bonneville tunes but I've got tons of other V6 stock tunes that I can show you the Decel tables for. Unfortunatly theres a bunch of them so you'll have to give me a few days to get all the screenshots for you.

    His dad has a 2000 3800 LeSebre and he has a 03 Bonneville 3800, and the closed throttle decel is VERY different. The 03 car coasts on like crazy, almost like you left the throttle open. Disconnecting the IAC at low idle and then drive makes a significant difference. So we feel that GM must have gone goofy with the DFCO/Throttle Follower settings.

    If you could find some I would like to see what they are like.

    Thanks!

    Not sure what all the settings are, my LT1 is quite different. The LT1 PCM definition seems very logical and straightforward, the newer PCM's/VCM's seems strange in comparisson.

    every computer is completely different...I've seen LT1 obd2 cals & I would venture to say they arent nearly as strait forward as LS1's

    I haven't got to look at a LT1 OBD2 PCM, yet.....

    Any plans on HPT to support 96-97 LT1's?

    Personally I would just convert it to OBD1 and call it done, but if you need emissions blessings, you can't get away with that in most places.

    If they add LT1 support it won't be for a long while.
