I've been talking to McMark for some time about the MS/ignition upgrade. I decided to to take the plunge a few weeks ago and asked Mark to put it on his schedule.
Jeff (JSConst) had bought a kit from Mark and decided not to use it, so I bought it from him. All of the pieces are together and Mark has time starting on Sunday. Unfortunately, my time is limited so I may not participate much. I will add updates as I learn of them, or Mark may do that if he has the time. |

Good stuff. Thanks to you all.
Sometimes having the prototype is a bit tough, but I'm sure Mark is sorting the process out and will have something to test pretty soon. We'll keep you posted. |

Mark
I looked at the log. Is the signal ground separated from the dirty (engine) ground? If not, that could be the source of the problem. For the cleanest signals, the signal ground and engine ground need to be tied together in only one place -- inside the microsquirt, which they did on the PCB. If they're tied together anywhere else you'll create a ground loop. It's easy to test if the grounds are tied together outside the microsquirt. Pull the connector at the MS and test for continuity between the signal ground pin (20) and the power ground pins (21 thru 23). good luck and feel free to call me if you want someone to bounce ideas off of.
