What conditions need to be met before a misfire registers? according to the log im getting misfire across an entire bank. I pulled a wire from an opposite bank and a few misfires register but it seems to bank the opposite bank misfire register even more. Log attached.
For my recent misfire problem on my LM7 across seven cylinders, I had to replace the PCM. I tried different spark plugs, different plug wires and bought a new AC Delco coil pack. I added to my already good engine ground cables. Nothing worked. This was also not false misfire because I could see the misfires on my old school engine timing light.
Then I swapped in a re-flashed junk yard PCM and that fixed it. The misfire graphic screen on my Tech2 clone is now clear.
