ms3x issiuses with spark on ls2 coils
Posted: Sun Jun 26, 2011 5:22 am
after some advise tbh ive fitted the ms3x and ls2 coils (built in igitors) , to my vr6 turbo engine starts and runs fairly well , but soon as im coming into boost engine starts back fireing , on wot , but isnt as bad on part throttle ,i lowerd the spark gaps but didnt help , i then did a datalog which shows im loseing missing sync issue keeps dropping to zero rpm, this only happernds comeing into boost , i was runing fully sequentail fuel and spark , also check igition and spark settings which are correct for this type of coil,
bare in mind before i upgraded to ms3x i was runing ms2 wasted spark which was fine with no issiuses regards this issiuse, only things thats been added is ecu upgrade, 6x yuko ls2 coils,,yet im told these coil are strong spark and ideal on boosted engines?im unsure how many milli amps tbh ,
so i thought id try my old coilpack to see if it sorted the issiuse but i had to add 3 spark triggers ,which ive wired like this
pin1 with resistor attached to no1 of the coil ms3x loom
pin2 wired wasted spark coilpack
pin3 engine ground
ie ms3 coil loom labled 1,2,3 are used 456 not used , but for some reason the engines backfires, ~(like the spark outputs to coilpack is wrong ? is this wired correct or is there something ive buggard up with? as i was just going to a trail run in boost to see if it still backfires?
ps my vr crank sensor is a 3 wire but only pin1/2 are used
any help would be great
