Is there any advantage to get the D-Jetro version instead of the plain jane stuff? I know I can go toss the AFM's out with MAP sensors with the D-Jetro. The car is still running the stock pair of turbo.

The only thing I can see is, I can go sell my Z32 AFM's to recoup the money spent on the PowerFC D-Jetro.

Thanks.

Wouldn't bother.

Unless you are chasing obscene amounts of power where the 90mm Q45 infinity AFM's are too small, keep the AFM's and just buy the normal PowerFC.

Why buck the system. Many more people can tune them with AFMs.

In my case I wish I got a D-Jetro instead of the normal Power FC. Apparently my combination of cams, turbos & custom intake resulted in "pulsing" of air through the AFMs making the car undriveable on light throttle settings (2 volt swings on the afms). This never would have presented a problem with a D-Jetro although my case is probably a more uncommon problem.

Like I've said before, the only reason was, it only cost slightly more for the D-Jetro AND the MAP sensor kit and at the end, I could ditch my Z32 AFM and sell it which works out to be cheaper than buying the normal kit.

slapper - how difficult was it to tune your car may I ask? How long did it took?

go_nuts - the tuner is having to make up a balance pipe between the 2 afms which he is doing next week, it will go back for a second attempt at tuning then, will keep you posted. In hindsight, the cost & wasted time with the Power FC was not worth it, I should have gone a Motec M600.

We have some wild GTRs running Wolf plug ins with no MAP sensor problems so the D-j PFC will be fine. Do you have a compressor surge problem or have you removed the factory BOVs?

Steve, its a rapid succession of chuff-chuff type noises coming out the compressor side of the turbos that only happens on light throttle - it is running a GReddy Type R BOV that is vented to the atmosphere.

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
