Does AEM EMS4 use these?
 

I have a non VVT 99 engine with TSE 12+1 Trigger wheel (99 Crank sensor) and Flyin Miata adjustable Intake cam gear with the two set of bumps (99 Cam sensor).

What does the additional tooth on the TSE 12+1 Trigger wheel do? Does EMS4 use that extra tooth on a non-vvt miata?

What do the second set of bumps on the Intake cam gear do? Does EMS4 use the second set of bumps or does it ignore it?


Thanks

The EMS-4 uses the extra tooth to determine TDC. It uses the cam triggers to determine phasing. If you're using the pickup settings we developed for the EMS-4, you need all three triggers on the intake cam.
