I just finished my aldl cable and hooked it up. The program I am using is winALDL. Here's my problem: I went for a short trip and monitored my readings during the drive. I am confused because my BLM's are reading at 108-118 below 2000 RPM's, which would indicate a rich condition. I also had my o2 sensor voltage pulled up, and that was reading any where from .526-.789, which indicates a lean condition. I am very new at this computer monitoring and chip burning, so any insight would be much appreciated.

Thanks,
Matt

 

In Closed Loop, the ecm tries to AVERAGE 14.7:1 AFR, so it runs rich for a moment the lean for a moment so you see the O2 over .44 and then under it.
