I used this write up to try and use my lc1 through the egr 5v on my '98 camaro.

However when I begin to scan, the PID grays out and changes to "unsupported parameter".

Does anyone know why? I actually pinned the wire to the pcm EGR pintle position pin (blue connector number 9 pin), since I was doing another project where I needed to repin a few things. EGR is enabled too on my tune.

Did you ever get this figured out?

Ya, I wasn't scanning egr voltage. Gotta scan egr pintle position voltage as well, so the formula for the custom pid will work.
