92 LT5 ecu ignition program and control - ZR-1 Net Registry Forums

Theg · 01-30-2018

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 .
