At high boost levels, I am getting an odd, intermittent misfire, which shows up in the datalog as a 16,000 rpm revs momentarily once, in a single row, then returns back to whatever RPM the engine was turning.
So far everything looks to be in order, and its just at boost over say about 13 psi, but it doesn't do it all the time, I am going to shield some of the wiring with some metallic braid to see if that takes it away,
I am running an MSD6a on the leadings, with new taylor wires, and the plugs are newer as well.
If anyone has seen this before, I would appreciate some insight..Max

 

Fixed...Grounded the shielding wire in the haltech Cas Harness..Max
