fell on its face

just as the title states. At around 2600rpm when i give it a full-on pedal stab, it packed its lunch and went home! now i can give it a quick half throttle stab and it does ok. im thinking that it may be timing related. With that said, im not sure that my Spark Retard histogram is set up correctly. If so, how should i view it in order to copy and paste? average? counts? + or -? what is the best way to go about tuning the gen 4 timing tables High/Low Octane, and Idle Spark Advance?WOTcutoutmaf.hplnew tq tablesfafm.hpt1.hpt

Disable your tip in limiting for etc. The only obvious place I saw in the log where you went full pedal, throttle went full throttle and then cut to 70%. I originally thought traction control, but you have that all off in the tune then saw your tip in limiting was still the only thing really stock other than some other trans parameters which you might also want to change. The 6 on/off torque switches above the transmission torque settings you might want to put back to stock. They can on occasion cause side effects. Also under spark retard - you tip in settings there too - 0 out v8 mode...

Ok. disabled tip in limit for ETC, put the 1-6 Max torque settings back stock. im not finding v8 mode under Spark-Retard
