I'm swapping a 5.3L L33 into a '87 RX7 and after getting it all wired up and plugged in I got a surprise: I hooked up to the ecu and found it shows it's from a '03 Tahoe. It starts and runs just fine but when checking throttle pedal the input shows 150% at wide open. I can't find a table to change this, am I missing something or do I need to reflash the ecu to a '05 pickup with the L33? I have a pedal and TAC module from the '05 L33, or at least they're supposed to be correct, not sure how to check them.

The only other issue I have is that the passenger side O2 sensor doesn't read properly but I'm tracking that down. Any help is appreciated.
