    Default DIS4 (6215) wiring question

    I think i have a failing channel on my DIS4. I am only using channel 1 and channel 2 on the trailing plugs of a rotary engine (firing 180 apart). Idling and free revving the spark on channel 2 is fine, but under boost i am loosing spark. I've replaced plugs, coils, wires, and verified the wiring is correct. channel number one is working perfectly. My question is, can i switch trailing 2 to a channel that isn't being used (3&4) and if so, what channel out of 3 and 4 should i use. Thanks in advance!

    I can't give you an answer, but interesting one plug has no colour on it at all.

    The only reason I can think of is because the plugs have only been run with methanol. I have another set that i warm the car with and also use when the fuel system is pickled with gasoline. It's just not firing when there is enough heat to discolor the cad plating.

    I can't see why you can't move everything(input and output),to channel 3 as a test.
