Calibrate AFR not working?

Post by Paul_VR6 »

Posted this in my Beta thread but figured I'd toss it here too. Running the latest beta (2nd to most recent files posted) and I set Innovate LC1 default and write the table and while running it doesn't match my LC1/XD1 gauge, reads about 6pts rich or so.

I'm going to check things on the bench tonight or this morning for volts vs afr to see what's up on the stim.

It has never not worked for me. I would suspect a voltage offset.

Hm, I thought I did have it working at one point on an older code though. I will check the wiring in any case.

Let me know what you see on the bench... That should be working fine. I will check it out on the latest firmwares.

I just used it this morning with the CVS firmware with no issues.

Something is up.. looking at some logs I was idling around 12:1 on the older ones and reporting ~7:1 now with similar VE. I'll be sure to get on the bench with it tonight.

Check and see if you have similar pw and corrections to match the similar ve.

Works totally fine on the stim. Not sure what's going on in the car. I'll try and toss it back in later today and do some checking. Maybe at some point the wire got grounded.

Got it, somehow my LC1 output 1 reset to narrowband after sitting. It's never the MS, never, even a new board with alpha code :?
