Didn't say it was a lazier way to do it but instead makes the TB itself lazy. Yes im well aware of the effective area table on top of the baro tables that are part of its definition.Quote:

New pedal came in and its installed, I checked the pedal wiring and throttle body wiring and its correct (gm 10379039 per PSI harness rep), replacing a leaking hydra-stop hose then ill perform a relearn and log..
OK, I spent about 30 or 40 mins on the phone with Nick tonight discussing this and other things. Basically he said for all of his gen 4 throttle bodies he has choked them off to flow the same as an LS3's tb up to just under 30% tps. For the LT's he's got them flowing the same as an LT1's tb. Above that it is the bigger tb size. For the 06 to 08 silver blades he said you will probably need to use something in the 3000 to 3500 range for the etc scaler and to not open any more than the 95% as mentioned. I think he was basically tired of people not setting the tunes up correctly and emailing him, so he went this route. He does make tb's for several companies now, so probably best to keep that in mind when dealing with other brands and to correct my earlier statement, he had switched to using an LT's motor in the past, but has since switched to something custom with better windings and even better at handling the constant amperage demand. He said he hasn't seen throttle flop issues in a long time thanks to that ;) He also said if it were to require more than 20% throttle to idle you might want to figure out another way to introduce airflow as it can start flirting with that fine line at going to the large tb area. Anyway, just relaying the info...
New pedal installed and performed idle relearn. Went for a drive and same thing 3200-3500 rpm power reduction mode bucking then it gets worse as you keep driving. Swapping the 112mm to 102mm TB I have off of my nova (I know this one works) once coupling comes in ill try again.:(
The blade is most likely hitting something causing it to not open for it to just stick around 30%. I would open and close it with the key on engine off via scanner controls to confirm then start taking things apart to see what's going on. If the inlet to the tb is too small or the blower inlet too small, either will cause it to bind.
ok ill try that now
The TPS starts at 28% and stops at 80%, is that normal.?
here is pedal log with the NW 102mm TPS starts at 26.3%.. idk
Are you getting the same code in REP mode? What is the code?Quote:
