Working on an 04 Vette, reflashed the PCM and now out of the blue the MAF will not fail causing the car to not enter SD........
Any ideas whatsoever?
I have turned codes 101-103 on and off 10 times, but the car will not even check to see if the MAF is working or not.
MAF Fail = 0hz
P0101-P0103
-SES Checked
-MIL on first error.

Have you tried unplugging it? Do you still not get a MAF fail?
2004 Pulse Red M6
Engine:
Patriot Stage 2 59cc heads, TSP 228R 112 LSA, Lucas 42# Injectors, K&N CAI, SLP Throttle Body, Catted SLP Mid-Length Headers, ASP underdrive, Magnaflow exhaust, HP tuned by me
Drivetrain:
B&M Ripper, LS7 Clutch
Other goodies:
BMR Drag Bags, Nitto 275 DRs, Pedders front radius rod bushings, Dual Aeroforce gauges, Cross drilled and slotted rotors, Factory chrome wheels
unplugged or plugged in, still won't fail
How are you verifying that it is not entering SD mode? Unplugging will cause it to, even if it is active in the calibration. Have you tried to zero out the MAF table?
if MAF is disconnected, it pretty much has to run SD
I know the car isn't entering SD because the car is dying 4 seconds after startup(going lean). with the maf plugged in, car runs fine. even with the maf unplugged, the car isn't setting any trouble codes.......

If it is dieing due to going lean, richen up the VE table by a certain amount. Just because the car won't run doesn't mean it is not in SD mode ... that is the default method of fueling and why I always tune both the VE and MAF. It is dieing because your VE table (SD Mode) can't supply the needed fuel to keep the car running. Post the log of the car dieing and we can help better with your situation.
Make sure that the Maf codes are set to no mil light, not no error.Originally Posted by DTM.Eric

yup, if you post your file its usually easier to see whats going on as well
It doesn't have to be perfect, it just needs to be done in two weeks...
