Finally got around to hooking up MAF sensor today and burnt a chip based off of $od_maf-experiment.BIN, this is for the truck in my signature. Truck fired right up idle smoothed out, actually smoothest it has ever idled. I have not got VSS hooked up at this time. Looked at TunerPro and saw that the O2 sensor was not showing up on dash or list, stays at 0mv. I have an A/F monitor and it is tracking along with O2 sensor. Also, I am getting MAF flowrate, but not seeing MAF signal, stays at 0hz. I double checked wiring, it was all ok. I then put my non MAF tune back in and unplugged MAF sensor and O2 sensor was showing up just fine with this tune on TP. Any ideas on what I am missing? I tried doing a search with no luck about these issues. Took it for a test drive, with MAF tune and it runs ok, is drivable, but seems like it is running lean. Thanks for any help.
