im clueless when it comes to moding the code
I think I'd rather kill fuel than fire, but as pointed out depending on circumstances leaning out could be an issue.
Just a theory, but I wonder if you can't power the coil with two alternative sources, a 12 volt and a much weaker voltage say 4-6 volt. Have a switching relay setup that when your shift light is triggered it kills the 12 volt source but activates the lower volt source. My thinking is that it should still fire to prevent loading, but with much less voltage maybe even enough to keep the engine from raising RPMS. Another theory..lol, I have lots.. is maybe using an flasher relay (turn signals) or similar that quickly switches on/off coil voltage during times when the shift light is active.
Sounds like it's time to add a 6AL, and have a proven limiter.

Stock RPM/Speed limiters kill fuel so I don't see killing fuel as overly harmful.Originally Posted by Six_Shooter
Nothing wrong with killing fuel, provided it's the ECM doing it, so that the entire injection event is killed and not cut off part way through an injection event causing a lean condition.
My suggestion was based more on the "add this" and "add that" posts and ideas that were starting to creep into the discussion. The 6AL is a proven and reliable soft touch rev limiter that prevents fuel loading up, due to the way the cylinders are dropped out.

You can't ensure the fuel is present at the right ratio for one combustion cycle and then cut-off the next when using a TBI, no matter how good the PCM is.
