I tested both 2,500 and 5,000 today, couldn't tell any difference.

Several have scoped it. Mazda runs them at 5 ms. I understand Jason's findings. With the stock wiring and 5ms running dwell, the coils are not showing signs of going into current limiting on a scope.

However at 5 ms, after a certain RPM, the coil spark cycles will be on top of each other. Around 5k or so IIRC, I've watched it on a scope. If you spend a lot of time at higher rpm, then 4 or 4.5 *might* allow a bit longer coil life span. You'd possibly be giving up a minimal amount of energy at lower rpms. It might be a perfectly acceptable trade off.

You guys should be replacing your stock coils anyway.

Bumping thread. It's two years later and I want to see what dwell time everyone is running now. How is your cranking now with it and have you needed to change your coilpack.

I'm still running it at 2100, cranking takes about 3-4 cycles before starting and I haven't had to change my coil pack.

Bull. NB2 is 5ms as well, I've scoped mine.

NAs where 8-16ms.

Would you really recommend that much dwell on stock NA coils?

I would definitely not recommend it, in fact you can't go higher than 8ms with the MS2.
