I swapped a 05 LS2 GTO motor and Auto trans into a 86 monte Carlo in which I used the 04 LQ4 ECM with vette tach and pedal.
Main purpose to go this route was for ease of old stock style cruise control function using ETC that without this configuration would otherwise be controled through the BCM on a GTO.
Problem Im having is a major lag in full throttle from a dead stop. Idle and starts fine. Part to mid throttle is great with no issues. WOT seems to have issues at high speeds but this may be a need to increase rev. limit?
Wondering if I have either a traction control and or torque management issue. Attached is my current tune. Any advise or direction on if its set properly is appreciated.
Thanks.
