lt1 and optispark

Postby krillian » Mon Jul 13, 2020 10:16 am

Hey.

Did a search but was not sure of the outcome..So..

What magic do i need to have and make my S80 pro work with Gm lt1 optispark ignition?

I know it is 360 tooth with no missing and inner circle is 4 different length slots.

Do you have any links to an image of the trigger?

or get rid of it

MS gives wiring details.

Although some posts online suggest people simply make a new trigger wheel to suit whatever it is they're doing. If you could get someone to laser cut or waterjet something out with bigger and fewer teeth in a more typical or known pattern

No i have not. Still not hooked up to engine.

Is power to DTA and just trigger sensor input enough to make it work for test/oscilloscope pic?

People make more user friendly wheels for the likes of the Nissan. If they were a similar diameter, they might be an option ?

What diameter is your wheel ?

From stevieturbo's post above, it looks like a variation on the Nissan CAS system. This particular one is not supported.
You would need to get a new one cut/fitted. If you don't want sequential anything, then simply use a 24-2-2 CAS trigger, giving the ECU a 12-2 crank signal.

Yes, that's all that's needed.
