My mod.
6266 single turbo.
fuel it stage 3 FUel pump
fuel it PI kit with bms controller and return line.
Precision racework coils and ngk 97506 gapped 0.022 (use dielectric grease)
fuel : e85.
mhd custom flash map with jb4.
1 meth cm7 meth nozzle at charge pipe.
compression ratio chaged 9.4:1 from stock.
forged connecting rod
forged metal bearing.
6 weeks ago, I got misfire on cyl 2. so I checked spark plug first...the center of insulator was broken.
I just replaced a new plug on cyl 2, after that got error code 30ba.
so I repaired dme mosfet.
car was fine on IDLE.
but still issue on cyl 2 when WOT.
always misfire on cyl 2.
I though it was leaky injector..so..swaped DI injector between Cyl 2 and cyl 4
but.. still misfire on cyl 2.
did swaped precision coil between cyl 2 and cyl 3. same issue on cyl 2.
after swaped PR coils...got new error code which is ignite error code.
so I just replaced new PR coil on cyl 2.
also I swaped PI injector between cyl 2 and cyl 5.
after that got new error code misfire on cyl 6.
so I though it was leaky PI injector.
but yesterday I got misfire code again on cyl 2 while normal driving on highway.
2 times broken insulator on cyl 2
1 time burned(??) ground electrode on cyl 2.
what cause issue on cyl 2?
attached photos about my plugs issue.
