I replaced my computer in a 97 5.7 4L60E 4x4 with a 0411 computer.
I would like to run CLSD without MAF.
I would like the computer to use B3647 for the commanded AFR and not use PE mode.
I would like the computer to use the O2 values to run closed loop when commanded 14.68 from table B3647
Am I asking too much!! I did the same thing in my 71 firebird with a 454 and MPFI and it works perfect. I have spent 30 hours now trying to make my Yukon work and it just will not. I verified both Hi and Low wires from all 4 O2 sensors to the computer. The only real difference from the firebird to the yukon is the yukon uses the CPFI, the spider injector setup.
Can someone at EFILive help me figure this out?
