I have been running MSII with EDIS for about 8 months now. Everything was running great until I changed the cylinder head, and now I don't have any spark advance. No wiring was changed with regards to ignition. No ignition related MS settings were changed. I went back and checked all the connections, and they are all good. Could the control unit have failed? I'll check the MS board tomorrow to see if anything became unsoldered, but I suspect something else is going on. Has anyone else experienced this before?

This is unlikely, but I'd check the ignition output on a Stim. If it's changed, try reloading the firmware and load an MSQ from before the problem happened.

Broken jumper wire inside megasquirt. Thanks for the help.
