EDIS plug gap ???
I have a 2332 wedgeport turbocharged EFI motor with a Ford EDIS ignition. I am experiencing a miss at 5500 or so and was wondering what plug gap you guys are running? Is more gap better? Is a small gap better for boost? I am running 15psi. I just need some input from you turbo guys. Thanks

Re: EDIS plug gap ???
As a general rule, boosted motors need smaller plug gaps than naturally aspirated. I'd probably try a 0.025" gap.
Re: EDIS plug gap ???
Well I went to 030. Kinda half way from the 035 I had. I may try both 025 and 035 again. I have a miss at 5000-5500 but the mixture is at 10.8 (supposed to be 11.80) I dont know if the spark is missing or the mixture is just going fat.

Re: EDIS plug gap ???
There is no value Gap vs boost for missfire.Spark plugs,spark plug wires,coils are factor of missfire gap point.I think you can start 0.27 and if no missfire try bigger and bigger since missfire detect.After detect missfire,0.05 close it.
