Tonyrodz's Tahoe Build Thread

PE is only active when you have it floored some of these trucks are set to a few seconds of delay and min of 90% throttle. in the tune you can change what tp% you enter pe mode. i set mine to 30%. stock was 90%. with your tune who knows if he made them settings lower and took off the delay.

if you can scan commanded air fuel ratio when you floor it it should drop to 12's vs 14.7 idle and normal driving. the commanded afr changing is the pe is doing its thing. so if commanded drops when you go wot the pe is working.

this pic shows the afr commanded and the wide band bottom row left bottom box. higher up you see rpm, speed, o2 sensor in mv tp%, gear, ect, ect. important part is the afr from the wb matching the commanded. this is from when i was tuning my 3800 with blower and meth injection. its almost spot on for what my goals were. 11.4 commanded and actual 11.4 on the wb. it needed a bit more tweaking form here, then the timing got turned up.

decel is when your coasting off the gas. it turns of the fuel as to not waste it. messing with that is how you get the snap crackle pop tune working when yo down shift, works best on a manual car tho lol

I'll have to try it later, thx for all the help guys. I think when it comes down to it--it needs to be tuned by someone who knows what the hell they're doing! Black Bear Performance!!!
