Do you get an immediate MAF DTC (i.e. either of: P0101, P0102, P0103)...?
Do you get an immediate MAF DTC (i.e. either of: P0101, P0102, P0103)...?
It does start but instantly shutdown, no martter if I give a little gas thru the pedal. But once I plug the MAF, It starts with no problem.
Yes I get P0101 and P0103, but I´m not sure if it was for the first attempts of starting the engine with the maf unplugged, because I scann the pcm once I plug the maf and start the engine.
What I note was that the engine did go to CL and LTFT are disable. I can go with the Log in this way or really the MAF has to be unplugged?
MAF has to be failed in order tpo tune VE...
sounds like something is wrong with your VE table... what mods do you have...?
Try this: copy B0101 VE table from a stock 2002 Camaro into your VE, and depending on mods increase it 5%-10%, and see if engine would now run.
Also, in C6001, set P0101,2,3 to A:1-Trip.
I got that Ve Table from Cal. Vet tunning.
My mods are:
6.0l Ironblock bored to 6.2l
243 ported cylinders heads 302 Int/ 290 exhaust
Custom camshafth 230/236 .612”/.607” 111LSA +4 advance
LT Headers, dual exhaust, torque converter TCI 3600 stall, 3.90 gears
Rigth now running the quarter mile at 11.45 seconds
In some cases Calc.VET does not get the VE right (especially if IFR is not correct, but sometimes we don't really know why).
So try this: remove the MAF, set VE back to stock and increase it by about 12%, and see if it runs... if it does, then you can do AutoVE on it.
Is your engine making around 450 FWHP...?
What injectors do you have...?
Do you have any logs of the injector duty cycle (need to log GM.IBPW1, GM.IBPW2, CALC.INJDC1, CALC.INJDC2)...?

For the elapsed times I figure it out that it must have more than 400 rwhp
I have the small 28.8 lbs injectors, here is a log of 11.6 seconds.
