    Jerking cts v

    Got a cts v 2009 that jerks at WOT any of you guys experienced that before?

    Car has a nick williams 102mm tb, ported snout , ported heads, 227/235 cam, fogger for nitrous, huge hx, icebox, and 5 inch intake and full kooks exhaust iirc.

    Car starts jerking only when it catches traction only. Also car is on id1000s


    Maybe fouled plugs? Afr is at 11.3 when its spinning, but wideband fucked up before it caught traction so im not sure on afr. Timing is at 13 degrees.


    Any thoughts guys? Ill post the file soon.

    edit: posted the file


    might think its the TCC lockup ?

    What injectors are you running?

    Just a stab in the dark.......I would put PE Throttle, MAP enable., RPM enable and rpm hyst back to stock values, throttle is too high now and I believe you may not be going into PE correctly....lean or set MAP to 85 and throttle to 10. Concurrently, unless you have tuned the wot levels to .77 lambda (11.0 AFR) using the 1.33 EQ ratio value, set EQ Ratio to 1.27. Will be able to better state when we see a log.
