Electronic Distributor Wiring Question

Hi There

I am currently doing a EFI Conversion to My Holden 6 Cyl (202)

I have brought a Haltech Elite 750 to run it all and am currently working my way through the wiring and configuration.

For the Ignition at this stage i was planning to run the original electronic distributor (reluctor based) with locked mechanical and vaccum advance.

The Distributor runs a bosch BIM024 ignition coil that triggers a standard "Dumb" coil currently.

I have seen others running a similar conversion wire up as per the following diagram.

Running this setup I believe I will need to change the coil to one with an inbuilt ignitor or incorporate a seperate module. Or is this what the Bosch module will achieve?

I am also thinking about making and running a 36-1 trigger wheel on the crank. This I think will not be required as all triggering will be run through the dissy but I will eventually change to individual coils.

Does any one have examples of this setup running and sample Configs in the Haltech software.

Thanks

Josh

Hopefully I'm missing something there, because from what you're saying, there seems to be nothing to establish TDC, nor crankshaft position, which are critical for timing the injectors, and with no load, air mass measurement, and/or throttle position sensors, etc, the ECU won't have even the most basic data for how much fuel to inject, nor what timing to use.

This is only a cutout of a larger diagram.

Have the normal sensors on the Elite for Load: TPS and MAP

The distributor has an inbuilt reluctor sensor with 6 positions to give engine position although not enough to run fully sequential injection.

I would personally do the 36-1 now and cut a few teeth (5) off the dizzy trigger wheel to give you engine position and cam phase position. The accuracy of a 6 tooth cam wheel for engine position is pretty poor.

Vacuum advance is a purely mechanical thing, I'd go to individual coils as soon as possible to gain control of the ignition system. Any alternative like an HEI or TFI system is just a side quest if you're planning to go COP anyway

Thanks for the feedback.

Ive attached a photo of the dizzy trigger for reference.
