92 LT5 ecu ignition program and control

[Theg]

Id like to gather info in relation to the ignition control of the LT5. I believe the crank signal goes to the ignition module and the module controls spark up to 400rpm then control of ignition is taken over by the ecu.
Id like to know what sensor signals are used by the ecu once ignition control is taken over .
In a nutshell I am trying to establish if the engine ignition would be sucessfully managed by the ecu if the fueling was added via carburettors and the injection removed . (Sounds odd I guess but this engine is in a hot rod not a corvette) . Trying to establish what sensors supply data that is used for ignition control and if injectors are bypassed would any sensors lost signals result in loss of the ecu's ignition control.
Any help greatly appreciated . Thanks to all .

Cool project.. wish I could help but there are few with info, hopefully they will see this

This pic is what I am considering trying to achieve.

Fake parts for looks on top of the motor? What is it in? Falcon XB GT?

What is it?

Its a Holden 1950 FJ ute . I chopped the back off it . Making it into a cab truck .

The carbys are real . Im going to graft onto the plenum if its doable. Sell the throttle body and modify the front of the plennum for a nice rounded look.

If I can do the carbs on the plennum or a fabricated new manifold theres a big advantage in looks for the engine bay having all ignition components hidden under the manifold .
Rod is going to have an open engine bay so would be very tidy without much visible wiring.

Do you have an FSM? What u r looking for is pretty much there.I’m assuming you don’t need to communicate w a chassis control module. That makes things easier. There’s someone in Australia that has a programmable ignition module that could work and replace the stock module.
