ECM:
Wiring harness for the ECM was pulled from a 1987 trans am, the ECM is from a 1991 so that it can pass the inspection to get street legal, there are a few wires that needed to be wired in the connectors to make this work, documented well on thirdgen.org for reference. The ECM has a Moates.net chip adapter and is running a modified bin, the computer I left with you has the bin itself on there with the tuning software (TunerProRT) and the maps/bins used. Distributor is set to 12 degrees and any change to that needs to be adjusted in the bin as well.
The Moates.net APU1 autoprom I left in the car can be used to connect the ECU to the computer to tune, do emulation and realtime adjustments, also can flash and burn new chips.

The parking break cables need to be replaced and shielded for heat from the exhaust. The outside protective layer got melted and made them not work properly, I disconnected them so the wheels would turn and they are tucked in to control arms so I could move the car, probably not safe to drive till these are replaced reattached.

Also has Dart Pro Aluminum 200cc heads that were customized to have 74cc chambers to reduce compression for a turbo/supercharger setup.
