So I compared my AEM and LM-1 Widebands today.
I've been running the AEM UEGO Wideband in my truck since the beginning and have always trusted it. I have had no reason not to. The truck runs great and I haven't blown it up due to false A/F readings.
Well, I bought an Innovate LM-1 Wideband controller to be able to tune some other cars and decided to hook it up to the truck and see if I could get it to work. All seemed good so I decided to have the AEM hooked up at the same time to compare outputs. To my suprise the AEM seemed to read about a half point leaner and also was not nearly as steady as the LM-1. I didn't have a chance to actually drive the truck. All logging was done in the driveway.
Questions/Concerns:
1. My bung is in the 6'oclock position (upside down). I realize this is bad, but thats where it ended up. Could this be a cause for concern that the sensor for the AEM could be going bad.
2. I'm not sure which wideband I actually trust. What are ya'lls thougts?
3. When setting up the custom pid for the LM-1, I have volts set at 10 and the offset is .63 instead of the recommended .625. It idle and free rev, HPT and the handheld controller seem pretty close. Could the variance change under load and WOT?
4. Any other recommendations?
Thanks in advance for the feedback.
