Missfire under boost what leads are best?
Posted: Wed Apr 26, 2017 3:07 pm
Hello
Im running chevy ls2 truck coils d585 (ones with the heat sink on top)
Im about to replace them as they are 10 years old and i have a more often than an occasional missfire over 1.6bar boost
My ignition leads are magnecor but 1 is oe ford zetec (one broke when i was checking them)
My question is would dta s60 be ok if i ran copper core (low resistance leads) or should i get the carbon / glass fiber ones with the steel windings (higher resistance)?would the ecu get interference off the copper leads?
Im going to be making them from a kit they need to be 4 inch long each
Spark plugs are. Bkr8iex plugs gap set to 25 tho
coil on time 4000 (apparently they self ignite after 4500 so i leave them at 4000)
I used to be able to run 35 tho gap on a bcr8es plug at 2 bar boost with no issues
so deffo coil issue i think
Thanks
John
