Jb4 Misfire

Aussieatlarge · 02-22-2019, 04:33 AM

One day with my new JB4 and cylinder 3 is dead. I had read that the jb4 was hard on plugs and coils but wow. 3 is dead on all maps. I'll switch out coil packs between cylinders tomorrow to check. Where to get coils on a Saturday.?

Sorry to hear mate
I have a set of oil coils if you need them
Located in Melb
Tbh I would ditch the JB4 and use the MHD tune
Download it from app store on android phone or tablet
JB4 is old tech and while some people are still running it without issue, MHD is safer, smoother and provides more features
Let me know if you need the coils

Talk about buyers remorse. How did i miss MHD during my research. The JB4 is pretty cool and works on my Avin style head unit.
What brand of coils?

Just standard N54 coils mate
Stick with the JB4 if you want, as I said people still run them

It is not the JB4 per se that is hard on plugs and coils, but the increased boost it provides.
