Wiring Diagram has no provision for it.

The original stock ECM/ PM is a (Speed Density based EFI system). Pretty crude, but worked simply by tables and on/off flag settings. The ECM coding at the time was never released per EPA regulations and nobody ever was able to burn performance chips for them as only the rebuilders had access. (I did get a look at a later 85 model turbo one that was hacked but just the tables could be viewed via a custom cable plugged into the diagnostic connector allowed access to change a few flags. A preset safety of the 84 TBI shuts off the injector at 4800 rpm in low gear only that I now know is triggered by the existing MAP sensor it a major limitation. I had a higher lift al lot of overlap and duration Reed cam in the car a year ago, that would have zero vacuum until 3,000 rpm where it just started building any vacuum allowed the engine to bypass that safety (no vacuum for the MAP sensor to trigger the ECM, and in low on an 1/8th mile legal street track setup allowed it to scream right up to 7K rpm in low gear. That cam was pulled out. But, getting rid of that safety w/ the Holley Term. X is the key. Currently short shifting 4,600/6,200 in D, to stay away from that injector cutoff safety that leads to a lean pop condition and massive loss of et if you get anywhere near exceeding 4,800 rpm in low gear only. That cure is what I need to finish installing. It runs great at sea level, at elevation tracks it is very rich, and Currently no provision or tuning capabilities to lean it out any further at elevation.

Ty for any input you may have on the ignition, IAC, and WBO2...and anything else I noted above. And if you need any other info I can provide it ASAP.

Thanks again Robin I appreciate any input or help you can provide in helping me with the completion and any other suggestions you may have to get the best options installed.
