I've bought a second hand PowerFC for my R33 GTST off another member.

He was running all similar mods to my car, as well as his car also being the same year model series 2.

Mods include:

  • Intake
  • FMIC
  • 3" Turbo-back exhaust
  • Boost set at 12psi

I installed the PFC 2 days ago, let it run for 30 min to adjust idle, etc.

Problem I'm having now is that the car shakes aggressively under throttle.

So what exactly could the problem be? Is there a known fix for this?

The last owner said I may need a touch-up tune, is there anyone in Canberra that can help me out with that for cash?

Thanks.

Bad idea running a tune off another car.

Best bet is take it to ESP/trojan etc, and dont tell them its someone else's ecu,just say the car is playing up and can they give it a quick run through on the dyno.

for now drop the boost back to standard and baby it.

How much should I expect to pay for ESP/Trojan to do it? I was hoping to not have to tune it until I get a few more mods done to save on costs.

Is there any backyard tuners in Canberra that can set me up with a basic tune? (just need it running smoothly for now)

    • So my rb is finally having more problems. 2 issues here but I'm here to just to mainly discuss the rattle noise. The other day when I turned on the car and when I take off or go in reverse, there is a temporary rattle noise but when I cruise, boost, idle it's completely fine no rattle whatsoever. I've also done all the servicing, all the health checks you can think of and it all passes with flying colours.  Also the rattle doesn't increase with rpm, it's only at a very certain rpm (slightly above 1,100rpm). My other car also has the same issue every once in a while. Changed the oil recently, no difference. Even took my oil to a lab and everything was quite good surprisingly. Timing belt changed a while ago to. Had the car on the hoist and can't see anything obvious. Tightened a couple of nuts on the exhaust manifold a couple of months ago. 2 different clips uploaded. One of them was supposed to another issue but I'll save that for another time. Thought I'd see if anyone had this same noise before, it's a bit hard to diagnose while it's intermittent. If I'm not mistaken, I think I had this a while back but can't remember exactly. I was thinking if it's doable I'll get someone to hold the throttle cable at 1,100rpm and hopefully it replicates the sound. rb25det rattle only.mp4 rb25det slow start + rattle.mp4
    • Haha wow, yes they do! Will sort tomorrow.
    • Yeah I’ll know when I take it for a test drive and I’ll double check the turbos as well when I have a look at it again.  Just thought maybe they might have done something in the head cause it looks like they’ve taken off the rocker covers 🤔 Thanks for your info! 
    • As Duncan mentioned it's likely a remapped ECU, like the the one listed in the link I post earlier:  https://minkara.carview.co.jp/userid/444260/car/444612/2099320/parts.aspx He quoted 444PS with an unopened engine and twin GT2510s @ 1.1bar boost... sounds about right?
