PowerFC vs PowerFC D-Jetro

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.

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      R33 GTR running -9 with no tune

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
