83% throttle at WOT
83% throttle at WOT Anyone know why my LS2 is only going to 83% max at WOT?? Tq management is all turned off (I think).
Also at .68 g/cyl, my spark advance hits 0* for about 200 rpm from 1400-1600

Pull the inlet tract into the throttle body so that you can see the throttle blade. Have someone go in and push the throttle to the floor and make sure the blade is open all of the way and that the throttle body cam is sitting on the stop.
If it is not make sure the floor mat is out of the way and that there is nothing binding the cable or throttle cam. If everything is clear then check the TPS sensor and make sure it on correctly. The computer gets it % reading directly from this sensor, if it is bad it could cause a false reading to the ECM.

Depending on which software your using GM decided to change the PID used for throttle position...if your using HP Tuners just log ETC Desired Position % rather than the old Throttle position SAE.

Same deal with mine. You need to look at ETC.. thats the real deal.. Never seen above 84 on TPS.. Usually 83 and then briefly to 84 and back down to 83. However, I have a problem with my trans temps showing up as 32 degrees. Whats with that?

Your kidding right? On ETC cars that is a stop so the peddle doesn't go to far.

This is a 2001 camaro ss m6. Just put ls6 conversion heads and cam. I noticed 80% on efi live and started to investigate. The throttle does not hit the stop, and i saw the stopper on the pedal. ETC is fly by wire, right? I have an actual cable.
I had a similiar problem. I was getting around 90ish% and my problem ended up being the throttle cable needed to be adjusted. For those that don't know...you can't actually adjust the cable by the plactic connector thing halfway up the cable.
