I am doing VE tuning with HPT and AEM Wideband and I noticed something odd...HPT has a preset config PID for "AEM WIdeband" so I use that while tuing and it takes the AFR parameter.

While tuning, the AFR displayed on the Wideband Guage is clearly always about .5 lower than what is shown in the Scanner.

Anyone have any ideas on this???

I have watched them side by side and verified it. Which one is wrong?

I would assume that the wideband Guage from AEM is correct...(I'm assuming you mean the AEM Guage)... I would post on HPT web forum and ask them directly about that problem.

I actually looked in the manual and did some calculations and the preset AEM foruma in HPT Scanner is right on. Not sure why its doing this.

Next I am going to log AFR vs. Wideband Voltage and see if it matches.
