Hi Guys.

Been trying to fix this problem for a while now , so thought i might see if any body ahs similar problems with there Power FC.

Basically , i have an r34 gtt rb25 neo,

It has a fair few mods, high mount , greddy plenum, cams etc. Makes approx 430rwhp.

It has some how lost approx 200hp.

Now ive basically done everything mechanical to it that could have failed , from comp tests to cam timing/ vtc gear solenoid etc, boost leaks, afm every possible thing

It still makes full boost.

The only thing thats left is a the Power Fc. When it was on the dyno everything looked to be working ok.

Just seeeing if anybody has had a simliar problem with there power fc ,dosnt have to be r34 neo.

Any ideas/help as im pretty much out.

Cheers Brad

I dont have a FC but i am curious about how you know you lost 200hp. Is it by seat-o-pants-o-meter or a new dyno run has been performed which states your engine now making less power with no signs of damage and same configuration of parts, same AF ratio, same ignition and full boost. If its now only making 200rwhp should be pretty noticable driving it!!!!.

Also it should not take long to work out where the drama is if its sitting on a dyno. Sorry im not helping but this is a unusual post.

Car went on has been on the dyno and only made 230 odd rwhp.

All the of the obvious things are ok. AFRs , timing , boost , vct operation.

If you looked at it on the dyno you would say there is nothing wrong with it , but it just dsont make any power, Thats why were thinking it could be a PFC problem.

Another note we put +5 degrees of timing in the whole map and it made no difference.

    • Interesting, I've heard complete opposite on my end. Bit of a lottery I guess.
    • Getting Dangerously close to being ready to go back in the car. Rockers in with clearance castings now (and a quick check with the USA for the torque settings for the larger custom bolts) Covers and ported FAST Manifold sitting on there. Not fully tightened down as there's some clearancing required for the water pump with the earlier LS1 water pump styles. Example of the clearancing needing to be done: The body has to be ground a little but I'm struggling finding an actual piece of it. The later variant of water pump resolves the issue as the manifold was designed around it. It only came on the VZ LS1 in Australia, it got a different pulley for Gen4 motors. (it also costs $450... vs... $0).

    • Doing some height adjustment on front suspension on a v35 and noticed this. The passenger side looks correct. So wondering what's happened to the drivers side?
    • Oh...I have the electric mirrors as well iirc ...they're in the same state as just about every other R31 door mirrors, with the 3 plastic screw towers broken/cracked in the plastic molding. All the interior is 'dry', so the mirror switches etc likely all work fine. Some pics below of the trimmer pieces ~ looks to me like previous owner, painted chrome finished trims with black paint ...ergo, the chrome underneath is likely a-ok... ...starts to look yukky posting stuff like this, how much did it cost in fuel on your last sortie up this way?...me just thinking aloud, borrow someone else's 4cyl to cut costs, come do your own pick'n'pull like before to save me some bother...hehe.. but whatever, I'll just earmark bits I know you want, because the way this is all panning out, I'll be able to retire the R31 from daily duty at long last, replacing it with a Subaru wagon I'm lining up in the wings...ergo, my attitude towards the donor pinny shell is starting to wane a bit, and I'm more than happy to help you out there... Like you say though, no rush...and I'll guarantee we won't be moving too far from this locale at any rate 😎
