You need the Boundary dwell control box- LINK does not have user control for the dwell.

I've got one sitting in my toolbox waiting to go into the car. I'm lazy, need to re-do my entire harness.

If you wish, you can build a dwell reducer circuit yourself: https://www.miataturbo.net/forum/t19780/

There are so many of my parts that end up like that. Paperweights! ARG

It will work with any ECU, on any car, that outputs a +5 active-high trigger.

The reference to OBD2 cars is due to the fact that the timing constant was optimized for those cars in the original design. The Toyo COPs like to see about 2 to 2.5ms running dwell, and the '96+ cars run just over 3.5ms dwell, so the board was designed to knock 1.4ms off the dwell time. (I run mine at 2.5, which is a bit more than Jason designed the circuit for).

The only difference is that the early cars dwell for a bit longer: 5ms by my own observation on a '92. You can tune the amount of dwell reduction simply by altering the value of a couple of components.


Or you can just man up and give $47.60 to Boundary Engineering. The board they sell is an exact duplicate of the one we discussed the the thread I linked to.
