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

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.

      Boost level and torque curve

      By Lithium · Posted

      There is a LOT of stuff that can be done, it all depends on how much time and money you want to spend on doing in.  Not all ECUs will be able to do it, and the more control you need the more time and knowledge needs to be put into making it work.  If you're willing to spend the time and money and have the right hardware and skills involved there's a lot that can be done.

      I am impressed with all this level of adjustment. I didn't expect all this possibility

      Boost level and torque curve

      By Lithium · Posted

      Correct.  In the case of the 500kw dyno plot I showed you the car actually runs two boost control solenoids for boost control and a 5psi wastegate spring.  It allows me to control how much boost pressure is applied to both sides of the wastegate valve at any point and fairly accurately control boost target as a result. I've tuned it so that it's able to target anywhere from 5psi to 25psi depending on what's needed.  The target tables I've set up in that car are Gear vs RPM, so every gear has potential for a different boost (and torque) curve.   First and second gear have quite low boost targets, third gear actually has different target boost all the way through the rpm range as it's a stock RB25 gearbox - the boost targets have been chosen to maintain a peak of 600nm (what the owner has set as the maximum torque he's happy with putting through the stock 3rd gear) but it carries that to the rev limiter.   The boost curve to achieve that is something of a ramp up, then hold, then ramp up again and the power curve looks more like a flat line haha.

      so you can decrease or increase the boost depending on the diet as you wish?     by acting on the wastegate?

      That's torque and power, it's all from a single run.  The boost curve is "held back" from it's peak target in the 3500rpm to 5000rpm range from memory, so it ramps hard to something like 18psi then climbs more progressively to 23psi nearer 5000rpm.   It makes the torque (and power) ramp more "natural" and less hard on parts and traction, it doesn't feel artificially held back.
