This looks like a reliable map. I would like to take a look at it, if you will.

Thank you.

The factory distributor in the 3B is not a 5 vaned hall sensor suitable for use as the main crank trigger. Did you use a distributor from an MC 10 valve engine or did you use it as a second trigger to the crank wheel?

Please elaborate on the setup as I looked into MS'n my 3B but shortly gave up after finding that MS can understand the 5 cylinders complex ignition math (for direct ignition) and special division circuits would have to be assembled.

Thanks in advance,
Nick
