Little Earth Wire From Ignitor Module

[RaZ_TuRbO]

Ive cleaned the connections with contact cleaner and the coils are splitfires with sparkies gapped to .8mm. Could the little earth wire for the ignitor module cause the a bad miss on WOT?

The car is a rb25det r32.

You mean you have not earthed the pack like its meant to be?

Why would you do that... Yes - it needs to be earthed, the wire isn't there for show

Wether its causing that problem, debatable.

Ive re-arranged it..but it might not be a good earth, so ill put it back to normal and see

ok, spent a bit of time on it this weekend

new plugs .8 gap, valley cleaned out.

coils have been siliconed, contact cleaned all plugs and ignitor module

Cleaned afm/plug and tps/plug

Its a terrible miss but ONLY on WOT. The car idles fine, and drives fine..its only when i floor it gets around 4000rpm does the car farts and pops, dumps some fuel smoke etc. It doesn't seem like a coilpack miss or the sort, more like a failing sensor of some sort?

What else should i try?

What mods?

The car was running fine, but then a slight missed occurred up high, so i changed over to coils with unknown condition, made the problem way worse. Siliconed the original and Changed back to them but the prob was still very bad..the slight miss has turned to a full breakdown . Everything has been double checked.

Supporting mods including ECU?

If not. try again.

yeah nistune

ok so replaced ignitor module with a friends..still no deal.

I just dont get it, the car is so well behaved and runs perfect right up untill a mash the pedal, then it sounds like anti lag! like bad popping and cracking.

Seriously i can drive the car perfectly its only when mashing the pedal, its soo weird.

Has your boost gone up at all since the tune, it could be fuel cutting.

[RaZ_TuRbO]

it might be an idea to just see how it goes just rnning off the actuator

4000rpm sounds like the afm

[RaZ_TuRbO]

Run the car off the actuator which is about 10psi, the problem not as bad, but its still definetly bad.
