Angry ms signal

how do you tell the incoming signal on a mega squirt. Not on a miata (my car is fine ) but i am installing a ms on a 240 with a distributor and no problems till i get to 4500rpm then the tach drops to apx. 2000 and it starts back firing. Same problem no matter what free rev or a load no difference?

Sounds like a rev limiter to me. Have you checked the rev limit settings?

Also, post an MSQ and a log.

The same problem. It has to be something in the ms or the signal because even if i am in my fuel map it also drops to the 2000 range weird.

It's definitely a problem with the RPM input - I've looked over a data log he sent me and the RPM signal gets cut in half at the point he mentioned.
