AFR Error Histogram Is there a thread anywhere that tells how to get this histogram to work properly. I've tried the demos, googled, searched, etc and no matter what I do I get unsupported parameter when I try to use it. What am I missing?

I have the standard version so I'm running it thru my AC pressure switch. I was able to play around with a custom PID and revised the formula and it seems to be working now. I feel sorry for anybody trying to figure this stuff out alone!! geesh!!

I don't have my laptop with me at the moment but if you PM later on I’ll share with you what I did to get mine to work. But basically you have to look at the current formula in the AFR error histogram and replace the sensor/formula with your EGR sensor & formula.
I also just stumbled into this. It basically takes you through all of the steps.
