Please help, PID not working. I have read all the threads i could find and I wired up my lm-1 to the brown wire and then in the scanner i went to pid's and checked to see if hpt was geting the signal by selecting the egr postion (v) and it has the correct volts but when i go and try to create my custom pid ([PID.2811]/.53)+10, it doesnt work, so i dont know if its the software or somthing im doing. any idea? thanks

Mine works fine through EGR
My lm-1 setup 0=10:1
5=18:1
1/12 rate
now in hptuners go to conf hist.
at top right click pid
go to user defined........ config user defined
pick an undefined number
name it
go to bottom under funtion
and type in your formula mine is [PID.2811]/.625+10
close custom pid window and make sure you click save(commit changes)before you close config window(thats got me more than once)
Af ratio error pid is 100*(([PID.2811]/.625+10)-[SENS.121])/[SENS.121]
hope that helps i had a terrible time with it but finnally figured it out.

Ahh.. success, i got it to work, it was somthing so simple it makes me feel stupid, anyway yes i was looking at egr postion in volts, in the table display, and i had a signal, thats y i knew it wasnt hardware, but anyway if you go to histogram configuration and click on 6. VE-wideband 02 and then look at Plot Value, the 2 to choose from are grayed out, all you have to do it click on it and setup your pid, i saw the first one (sensor i just didnt see the other one to the right (PID and thats where my problem was, clicked on PID: set it up and bam, it worked. anyways thanks for your help guys.
