Topic:  TBI on Buick V6  ODD-FIRE

This project has to do with running a Chevy 4.3 L  TBI on a Buick Odd-Fire.
This is a 1976 231 Engine with a HEI dist with a vacume advance
It has been done with Buick Even-Fire engines.

Howell  says that it cannot be done because the odd-fire.
Odd-Fire  HEI pulse confuses the ECM with its odd-interval pulses.

So I am considering getting even-interval signals off of a Crank Trigger--- 
Holley markets such a Crank Trigger and sensor for even-Fire Buick V6 
engines, to run performance ignition systems.
This  Buick V6 even-fire crank trigger fits onto an Buick V6 ODD-FIRE
and will send even pulses to ----?


Question:  How do I route/convert Crank Trigger Pulses for  the 4.3 ECM to 
run the TBI?  I think that all that is needed is a square wave or on/off 
signal at 12 volts?????  Could this be a direct connection??
or is elaborate conversion needed???
