EGR to AFR with HP Tuners

2000 Trans Am
Trying to make my innovate lc2 wideband read AFR on my HP tuners through the EGR.

I have the output 1 going to the gauge on the wideband and it works perfect. I have output 2 going to the egr + on the pcm and it wont read on my HP tuners. My tuner setup the config on hp tuners so that is all good. Just trying to figure out what im missing. Do I need to ground a wire or something? I might have it connected to the wrong wire on the pcm. Which one is the egr on the pcm?

Thanks for the help.

What does it say in the scanner? will it log anything at all?

Your custom PID should be 100*((([PID.2811]/.332)+7.5)-[SENS.121])/[SENS.121]

EGR is pin 55 on the blue connector. Also make sure EGR is enabled in the tune and you are also logging EGR on your table display.

Good information right here. Totally forgot to make sure the EGR was enabled on mine. Good luck OP.

Thanks was on the wrong wire.
