AEM AC pressure question
AEM AC pressure question I hooked up my wideband today via a/c pressure sensor, and my readings are off in the scanner.
Aem read 15.1
scanner reads 16.1
I am getting power from a fuse in the fues box and it is grounded behind drivers side kick panel.
Let me know if i did somthing wrong.

I'm curious about this too. You can adjust your calculation that changes the voltage into an AFR, but that is going against what the manufacturer recommends for their product and all it does is make the HP Tuner software match the widebands' reading. The question is, which reading is correct? I would tend to agree with the wideband reading, but you never know.
I wonder if the wire to the wideband gauge and the 0-5v output that you ran to the A/C switch are connected to each other internally in the wideband hardware. If not, could the voltage readings on them differ by a tenth of a volt or so? Just thinking out loud.

How accurate is it now?
