Problems loging AFR using AC switch Wrong PIN maybe? I posted this over on the HPT forum but not much help. Can somebody tell me what I'm doing wrong? I'm trying to log AFR using my AC pressure switch. The is the formula that I'm using and the error that I keep getting in the primary table [PID.7101]/.5+10 "unsupported parameter"
I have looked at the demo for setting up custom PID, Histogram etc and still no luck. PLEASE HELP!!!
Is the correct wire on the PCM that I should be wired to Red14? I think was going to the wrong spot at first but I'm still not having any luck

I think I figured it out. I had three problems.
1. I had to add the PID for AC pressure to my main table to see and voltage.
2. Because I made this harness myself the AC pressure circuit had been removed. Originally I had the wrong wire coming out of my PCM. I was trying to use the 5V ref. instead of the pressure signal wire.
3. Added my custom PID to the main table and it all seems to work now. I hope this helps the othe newbies.
