Okay,

My coil packs have died for a second time, it's misfiring again on 9-10psi.

I need a way to PROPERLY diagnose them, they are series2 coils if that helps.

The old 0.7ohm's between pin A and C means nothing as they all read a perfect 0.7ohms. So that theory is out of the question.

Does anyone know a RELIABLE way to check which one is shagged ?

Get a set of known working coils and put 5 of them in (with 1 original coil). Then work your way down from their until it starts missing again.

That's what I did although I used electrical tape instead of fresh coils. In the end just bite the bullet and get a set of Splitfires :cheers:

benm's right on the mark. I could never get a failed coil to register and different resistance to a known good one. After doing the substitution caper a few times, I just ended up going with the Splitfires. They are now coming down in price and they really do make a difference.

Do what benm says mine kept on going one by one, did 4 of them before I got a set a spitfires, should have done it sooner and saved some money.

There only about $600 direct from japan for the set, rather than about $300 each from nissan and about another 10rwkw some people believe.

3 of mine died at the same time, 2 more badly than the other one.

you can see quite easily which one it is by taking the cover off and watching them in the dark while the car it hot, you can see blue flashes as the spark arcs to the metal frame surrounding the coil..

try that method, it worked fine for me.

and in the end even after aralditing which did not work, i got spitfires.

they have been in since friday and the problem is gone, plus performance is more responsive, i dunno about much more outright power though(like 10rwkw!), it feels like only a little bit when compared to before the coils started dying.

    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
