WTF is up with this 2001 camaro speed density Going speed density on a 2001 camaro...So i set MAF fail frequency to zero, then deleted codes.. With fail frequency to zero car ran great UNTIL we unplugged the maf... Now the computer should have ignored the maf with the fail freq at 0 correct? MAF error codes did show up until i deleted them with a reflash.
I then put an old tune back into the car with normal maf freq and codes and it runs fine with maf unplugged.
So WTF is going on here... I have compared both files and the only differences are some timing i added, idle air changes, fail freq and the codes. That appears to be it.... how can this happen?? The car on the modded tune runs so lean at idle its off of the widebands range (its not the idle air either very minor changes to help new cam idol 1.5 g/sec across the board). The car with the other tune would go so lean that if you tried to rev it it would die. Now funny thing is i was sitting there watching injectors and as the car was leaning out and dieing the injectors were supposedly opening and read as high as 6ms at idle. Didnt save logs unfortunetly. But injectors went up as car leaned out. Doesnt make any sense....
seriously wtf....
