Ignition upgrade

Post by m2cupcar »

New driver added to ignition in place of XOR gate. 100k resistors from JP7/JP8 to ground. <That fixed noise issue with load jumper in place that was creating spark at plugs.

First start

Post by m2cupcar »

Actually second attempt just minutes after the first. Was obvious it wanted more fuel so I bumped the lower zones/cells roughly 40% and this happened:
