I am in desperate need of help. I was having a ton of issues with megasquirt and I thought updating the firmware may help. Well after the update finished and I loaded the previous tune I had, the engine wouldnt fire. Is there a setting that doesnt come a long with a tune that I need to update? I am clueless and pretty screwed right now.
Is there a chance I fried my coils updating the firmware? I also had the following issues loading the map

What version of megasquirt. Some versions dont burn up coils when flashed. Also my advice is to leave it alone for the day. No need to get mad at it, only makes it harder to fix.

But you might have remembered to unplug the coils if you were relaxed. If you have to set the coil output to inverted then its possible they fried. Someone else who has used ms2 will probably chime in.
