I know that people have connected Hptuners to the EGR for Wideband logging, but has anyone ever done it with the AC pressure Voltage line. I dont know if this line even exist on our trucks, But there are some post ever on tech that are done on the F-bodies.

Appartly connecting it to this 5V AC source will allow you to do some WB logging.

 

TTT for my knowledge

 

Over on the HPT forum look in the advanced IO section.
I believe some guys have used the AC pressure wire.

 

I will look you know if there is a pressure wire on our trucks.

 

I haven't checked, But I'll try the PID tonight and see if it's supported.
