So I'm getting random voltage spikes at about 5 or 5500 RPM we have alternator control turned off. Don't have the option to turn on high speed feedback on the alternator control only closed loop. I'm wondering if updating the firmware will get me that option.

I bought the megasquirt used it's a black box with a big harness and when I went to look into the firmware update it said megasquirt - 3

I can share logs and tune later as I'm walking into work.

We solved it! Broken solder on the knock board! Fixed it up and she is back to better!
