Thread: Wideband PID

I'm running an AEM WB and got it to read through the EGR signal to the PCM. I'm using the PID [PID.2811]0.5+14. Right not HPT is telling me that I'm at 15.4 afr at WOT when the gauge is reading 10.8 so I know something is off. What PID are others using with the AEM?

Got it figures out, replace the 14 with 9.4 and it's reading properly

I'd do a search at HPT forum and copy what others have done for that wideband. Taht's how I setup my LC1 and it was right on.

Another idea is.. does it need to be free air calibrated or anything like that?

Not like the LC-1, I tried to set one up on my car and couldn't ever to get it to function properly. Them AEM calibrates inside the exhaust, MUCH simpler to setup that the LC-1.

I have a friend with the AEM and he went through the same headache, so between the forums and him I was able to figure out all that I wasn't able to get right.
