Hyperdrive remapped my ecu.

R32 is 10psi stock, and my untuned ecu handled 14psi through the stock turbo and 12psi through the RB25 turbo (still didn't hit R&R but it pinged when on 14psi).

My guess for the misfiring is the coil harness, I had mucho problems and was swapping coil packs in and out. Turned out it was the plugs that go onto the coilpacks - the insides were falling apart. $120 for a new harness and it's mint :P

lol cheers :( which one?:P

You can get them from Nissan but when I asked they had none in stock, was going to take 3 weeks to get here.

Ended up getting it from RHDJapan and with shipping worked out pretty much the same as buying it from Nissan but I got it in 1 week instead of 3 :P

I got the R32 GTR coil sub harness --> here

But likely due to our dollar sucking so much ass, they seem to be $275 delivered now :P

I'd ring Nissan and see how much they want..

i can ask my parts guy for a price and ill get back to you on that

Definately recommened a Nistune and s1 turbo. If you have a spare bit of cash, get an EBC. You wont regret it!

If u r referring to an Electronic Boost Controller(EBC), i've got one of those.

Cheers R33 Nick, hear from u soon!

Just wondering.. are u using a pod filter? Cause previously on my car I had the similar problem.. all i had to do was take off the filter(apexi pod) and use a lightpowered airhose and blow out all the dust and stuffs.. ended up solving the problem but eventually changed the filter after a month :)

Just my2c.. hope it helps! ;)

*Edit* sorry didnt see u had mentioned having a pod :)

Try cleaning you airflow meter sensor with some brake cleaner could be dirty and pull ur intercooler pipe off the turbo if there is oil in there your turbo seals could be causeing the problem, even try adjusting your timeing

My understanding is the standard R32 ECU adjusts timing on its own until it detects knock then adjusts it back abit, rinse and repeat.

Btw don't clean out your pod filters with an airhose it can damage the material, which is why K&N etc have cleaning kits for them.

The ecu has timing maps, that's where it gets its' timing info from.

The maps are relative to the base timing though, so if you adjust the CAS it adjust timing across the board.

No probs. I still think it's a spark issue (breaking down) as opposed afm or oil in cooler like that other guy reckons. When you have 20yo wiring/plugs, you would want to look at replacing them just for the hell of it (especially mission critical wiring).

yeah it seems to me that its the same problem i have, which is coilpacks. Its 90% chance to be the coilpacks and well they are worth replacing at any rate. Our cars are old, its worth going through and replacing things. Hence why I've got alot of lines and fittings etc that I'm in the process of measuring up to replace. 20y/o rubber and wiring needs to be replaced or checked at some point.

Might not necessarily be the coilpacks themselves, while it is common there can also be issues with the wiring associated with the coilpacks. I spent a few months troubleshooting a misfire and it turned out my 19yo coilpacks were fine but the plugs on the harness that connects to the coilpacks were falling apart.. everytime I took a plug off the insides would disintegrate more :down:

My stock coilpacks were so fine in fact, that I ended up selling the splitfires I got when I was troubleshooting.

      Wheel refurb?

      I was wondering about this. I'll do some research.

      Why not? Since mines been built, I've used low boost maybe 5 times.

      gauge needle removal

      By GTSBoy · Posted

      Yeah, so widen your search to any Nissan speedo first, then go wider if needed. I will say though, that there is a better than even chance that what I said first will likely come into play. They quite possibly won't come apart without damage. I tried to disassemble a stepper gauge that I wanted to repair. There was no way that needle was coming off the spindle, and I could not see how the spindle would come out of the mechanism behind. Assembled once, never to be disassembled, was my conclusion. Could be the same on the R34 cluster. Failing that - take the cluster to a workshop that specialises in automotive instrument work. There's usually at least one in every Australian city. They'll either be able to do it for you for small cost, or tell you it can't be done. It might be that "it can't be done" unless you follow some arcane procedure, including trickiness to glue it back together or something, that only experienced techs know.

      R-chassis INNER tie rod torque spec?

      By GTSBoy · Posted

      Well, given that I, an engineer, almost never bring out the torque wrench to tighten up chassis bolts, despite fully knowing the theory, and instead rely on feel, which I happen to know is exactly how the majority of mechanics do things, should tell you the level of actual peril that exists from not achieving exactly 88 Nm of torque. How about if I just say then that 88Nm is at the lower end of the correct wheel nut torque range? Everyone knows how to tighten a wheel nut, right? And almost no-one ever brings out the torque wrench for that task

      Don't be ridiculous. "2-3 ugga duggas or one Oof. You have to use Oof on tie rods because you can't get an ugga dugga on there." Is not helping the guy at all.
