you have an iduino based version? using .73/.74? Any code tweaks?

Is there any pattern to when it resets?

like after a certain amount of time or distance or fuel usage or right when you start the engine or use the horn or kill switch or ???
Iduino - Yes
Version .73 no tweaks
No pattern random (main problem with tracking down too can't duplicate at certain intervals)
Just when either shutting off with coil kill or ignition. No other items causing it.

Hows your ground? Is it connected right to the car frame, or another ground wire that might be getting fishy signals when you kill the engine?

I also wonder if it might be getting a spike through one of the data input lines. Maybe try higher value resistors in the data lines?
Uses a connector but a good one, no way could be loose connection there. I believe also not a power issue anymore as well.

Actually I have not checked ground, I may look into this tomorrow.

I was wondering same thing on spikes on inputs. How much larger of a resistor should I use in there and still receive signal?
