Hi, I been search about a problem on my megasquirt but no solutions found. The problem start when the positive terminal of the battery touch the ground for about 15 sec. the car was running ok after that wont rev, wont pass 1500 rpm.
ECU info

Megasquirt MS-1 3.0 version, fuel only.

I ck the ignition system (MSD) they are fine.

A friend of my repaced the CPU and reset it, problems still. he said the board is bad.

thanks.

Can't see why a short in the battery supply would affect the MS. Best to post your MSQ and a log here.

The mere fact that it is running, would tend to eliminate the board.
