No tach signal - MS + DYNA2000 on bike

[KAWA 900 TURBO]

Hello

I am connecting a MicroSquirt V3, along with a DYNA2000 on my Kawasaki Z1 Turbo.

All signals works fine, but i cannot find out how and where to connect MS to get a tach signal.

The DYNA2000 is a Inductive type system. Not a CDI.

The DYNA2000 has separate Tach signals that provides a squared signal with 1 pulse/rev.
This pulse is 1-12volts dep on rev.

The negative wire to each coil is also providing a 12-14volt squared signal.

I tried to connect the DYNA2000 tach signal to OPTION+ pin 30, and OPTION- pin31 to the ground, but i get no tach signal.

Can someone please help me how to proceed, i have found a lot of topics in this forum regarding the same tach signal problem, but i cannot find the answer that helps me.

Best regards

Do you have a link to the documentation for this particular ignition?

Not sure if this will help you or not but I sell an optical ignition system that has been integrated to MS successfully.

Initially we had the same issue, no tach response, but on the bench and on the bike we had a signal with an analog gauge.
The fix was the the tach out from my controller to Pin #32 ans jumping ground to Pin #33.

I use Dyna 2000 with microsquirt V3 with no problems, fuel only.
Use yellow tach wire (5V square wave) to pin 30, and pin 31 to earth. Ignition settings - Rising edge, Trigger rise, Trigger wheel teeth = 0. That should cover it.
