I just went over some back and forth e-mails with the tuner from back in the day, as well as pulled down the ECU to inspect the wiring.

I had been using the CPC input as a trigger from my meth injection controller (0-5v switched), as well as the wideband input into the rear o2 wire. The rear o2 wire was snipped, but is reconnected and soldered/heat shrinked.

Nothing weird on that side of things really. The float/fuel pump setup was out since the car was running is the only other thing I can think of.

Is the canister pressure sensor built into the charcoal canister which is in the rear right wheel well? I suppose swapping that out for another one would be the next move.
