Im looking at buying a power FC and controller for my GTR R33. Also the boost controller thing to suit the Power FC...

Any way....

I have noticed there is two types.. whats the differance between the two?

Regular Power FC + Commander (under $1000)

OR

APEXi D-Jetro Power FC + Commander (Over $1000)

Whats the differance between the two???

What is the "D-Jetro" model and do I need it?

The D-Jetro Power FC units carry the same functions as the regular Power FC units but do not require the use of the factory standard air flow meter and use a mass air pressure sensor. Apart from the unit itself, use of the D-Jetro units requires additional parts that vary depending on the model." - www.greenline.jp The airflow meter (at least in the skyline range) does not pose a big restriction in terms of horsepower and one would doubt the use of the D-Jetro. If you really need massive airflow you can always change to 2 x Q45 Airflow meters and use those with the PowerFC. The skyline series are optimized for closed loop operation with an airflow meter.

The Djetro version has a few caveats you should know about before you consider using it

Careful placement of the map sensors in multiple throttle body systems With multiple throttle bodies, such as the Skyline GTR RB26 or the Pulsar's GTI-R SR20 multiple throttle bodies can have bad side affects when using a map sensor system. Consideration needs to be taken into account when placing the map sensor (or map sensors) for the Djetro system to avoid idle problems on multiple throttle bodied engines.

Tuning will take considerably longer It will take considerably longer to tune a Djetro PFC over a normal LJetro PFC. This is because all of the work has to be done from scratch instead of just doing the main bits in the AFM/LJetro version. You should discuss this with your tuner and find out the total cost for a Djetro tune.

APEXi POWER FC (Normal model) - What does the unit do?

The unit is a full replacement ECU for your factory computer. It is not a piggyback system and as such allows full control of the engine and computer controlled systems. It comes with a base map of your cars computer with base map tuned for basic mods such as exhaust, boost controller, air filter upgrade. "The Power FC is a complete, stand alone, total engine management system capable of handling virtually anything thrown in its path."

      My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
