Got the car dyno today made 206rwkw with HKS 2530 FMIC and PFC. Now when I shift at high rpm (5000+) it will bog down with a cloud if black smoke on the gear change on every gear. I have done a map trace and checked Loads that the PFC used on the gear change and all is good. Second thing is I can not modulate the throttle to control and drift as the car jerks violently,eg if you boosted to 14psi and back off then on again, But it drives fine with good a/f mixtures. :D

surely you culd tune around a atmo bov with a pfc? atleast i hope so cause thats gona be the case soon for me.

Only if the tuner knows what he is doing, many don't.

Take it back to whoever tuned it and tell them the problem.

:nyaanyaa: cheers :happy:

or fit a real working blow off valve, as nissan had intended it.

a plumbback will work best for your car, turbocharger and ecu/tune.

i suspect this will be much cheaper and a far better solution than tuning around it.

    • Not sure if you're being serious? I, and all the car people i know, ALWAYS use a torque wrench for wheel nuts. I assumed any car person, apart from tyre centre monkeys with rattle gun in hand, would do it properly.  Anyway, no further reply from me on this unless legit discussion from OP or his query so, over to you, knock yerself out.
    • I was wondering about this. I'll do some research.
    • Why not? Since mines been built, I've used low boost maybe 5 times.
    • 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.
    • 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
