TFI module running off duraspark dizzy?

[Lazy JW]

In terms of making the DSII output into a square wave for TFI, by using a zener diode that is slightly lower than your peak voltage, you can flatten the top of the sine wave...

Yup, it should work. A square wave is really just a sine wave that rises VERY quickly and has the top chopped off.

This has been very enlightening, thanks 8) I'm thinking of Volkswagen breaker point ignition triggering an HEI module

well I sorta have it working....

well it is just a TFI distributor with a EEC4 coil. no duraspark but it is RUNNING!!! EFI here we come!!
