Update - I did speak with the owner of Torqhead and he had real good reasons for not continuing to use the optispark in any form, though he didn't think what I proposed was beyond possible. EFI connection did not provide any information but given the quality of his products, I'm sure he chose not do use the trigger wheel for a valid reason.

I did get my first project car back on its feet yesterday; time to work on the next one, then I have time to play with this more.PXL_20210123_204803175.jpg
