Want to install a GM LS2 12570790 / 19420034 silver blade or LS3 12605109/19420707 gold blade 90mm throttle body onto a North American LS1 or LS6 car? Or onto an electronic throttle 2000-2002 GM V8 truck?
*Notes: For faster idle learning after a calibration re-flash or battery disconnect, you can correct the throttle size in the vehicle calibration. For a 90mm throttle size we use an "ETC Area Scalar" value of 0.0158.
LS3 throttle body may require reducing the maximum throttle opening in the vehicle calibration. For example, if the throttle blade hits the wide open stop at 98%, reduce the maximum position to 98 - 5 = 93%.
