Thread: car is a turd off the line

  1. #1

    car is a turd off the line

    09 g8 gt with lsa swap, baby cam, full exhaust, 4" intake, and stock 6l80 with zl1 converter. Tuned on MAF only

    i have 80lb injectors with adjustable aeromotive fpr running at 60psi and dual walbro 450's.

    Trying to figure out why it pulls a bunch of timing when i launch at the light.

    Which Torque management are you hitting? Most likely Launch. If that's the case, you can reduce the effect by upping your Spark Minimum - TqMgt to a positive value - like positive 10-14*.

    Try and log Spark Torque Management Type

    Here's what i came up with. New tune file to take out every bit of traction control and the log after flashing.

    Well in that log it appears that the car is actually reporting knock and the spark torque management type never changes, so I don't have faith that it is torque mgt. Is it possible you've got some exhaust hitting somewhere on the car or anything like that? I would add every channel with the words "advance" and "retard" that were available for your vehicle to see if you can see what's happening, but the car seems to be logging "knock retard" itself and alot of it at that.

    The exhaust is tight. I feel like there is some noise the engine is picking up from the SC. I have a solid isolater but i have a feeling some noise is coming from there. Anyone ever encounter this issue? how did you fix it?
