I was just talking about a datalog from MegaTune, then looking at it with MegaLogViewer, people in the Megasquirt forums usually just post screenshots of the areas of logs they are concerned with, and then attach the complete datalog.

I don't know of anyone who's been able to run the v3 board with spark without taking the stock ECU out of the picture. It's just too sensitive to all the noise that gets induced with all that extra wiring everywhere.

I'm pretty sure you're going to have to run a dedicated power, ground, and signal line from your MS to the crank sensor.

This was what made my car drivable with the MS1 processor v3 board, although, I did have to add some additional capacitors on top of that to eliminate some seldom spikes thereafter.
