Need TDC signal

Hello Guys,

I have a Fiat Uno Racing with standard LE-Jetronic and Microplex Igniton.
I'd like to install a MegaJolt but I have a problem.
I have a triggerwheel with 2 teeth for each TDC of the engine.
This signal is for the injection and the ignition.
When I install a 36-1 triggerwheel I don't have this signal anymore.
Is it possible that the MegaJolt make me this TDC signal?
I could get the signal from the coils but that wouldn't be at TDC.
The only otherway would be to install a 72-2 triggerwheel on the cam pulley or I modify a distributor with a 36-1 triggerwheel but this solution wouldn't be very nice.

I hope you understand what I want

Thanks for helping!

Regards, Martin

Hi !

Firstly - why do you loose the 2 teeth signal when you install MJLJ ?
Do you remove the wheel that these two teeth are on ?

If so, can't you keep it - and mount the 36-1 wheel outside it, and have both ?

If not - I have a modified distributor with a 72-2 wheel. And it works nicely. I got it started yesterday. But it seems to be doing just fine. I know there's at least one more user here - Alexander - having a modified distributor as well with a 72-2 wheel.
