Good tips, so does this mean you have yours running good again?

What is the max rpm you plan to run? You could try the 5ohm coils. What was your previous coil setup?
Maybe the battery is on its way out? I like to see over 13v when revving.

I hope the MegaSquirt experts can help with the settings.
I do not understand the 'time after spark' of 10ms setting.

I only understand, you should use at least 10ms dwell, and a minimum of 0.5mS "burn time".

So, the ignition should be able to maintain 10mS of constant dwell, until the RPMs get ...

Well, for the dyna coil, at 3 ohms, and a 12v battery, the most you will ever see is 4 amps. That is very low current (the ignition transistors should be able to handle that all day, especially with a heatsink), and i would just stick to a nice round 10ms. If your engine revs really fast, try 12ms.

Dyna 3.0 ohm green coil inductance = 13.65mH
I think you can increase your dwell quite a bit more with this coil. 3ms would be too short.

Are you sure it doesnt have a regulator in the tank? Mechanical pressure regulators work pretty nice without all that hassle.

When i use our "snifer" O2 sensor on the dyno, if the end of the snifer pipe is too close to the end of the tailpipe, we see extremely lean air/fuel ratios because of exhaust reversion. Fresh air is actually being sucked in and altering the O2 sensors' reading. I have to make sure the snifer is at ...
