Where to buy Apexi PFC D-jetro

[Fitzpatrick Speed Works]

Ive searched and searched and i cant find any info on the stats on, or where to by the d-jetro. I would prefere to buy it in aus and also from someone with the software for it ,any help is appreciated.

As long as you understand whats involved in tuning these things...

I don't know of anywere in aus thats selling them cheep ?

Try Japan www.greenline.jp

I think Croydons are the only ones in Australia with the genuine PFC Excel software, I have not seen any differences in the software for DJ's. We use the various versions of Datalogit and they seems to work OK as well. You just get a couple of extra options on the set up. Amybe pop over to www.fc-datalogit.com and ask a few questions about DJ's and software versions.

We get PFC's from Nengun, never had a problem buying stuff from them

so if i talk to nengun can i just ask for the power d-jetro when ordering a pfc .... and can it be tuned through the hc or does it only interface with a computer. SK are you saying you cant see why the croydon software wouldnt work???? I have talked with datalogic and they believe there software will support the d-jetro but i dont really want to buy the computer then fork out $550 for the software if i can do it through the hand controller!!!

The Commander tunes all PFC's as far as fuel and igition mapping is concerned. Just that some of the less used menu items aren't accessible via the Commander (same as all PFC's) and need the PC software to get at them.

The real question here is, why do you think you need a DJ in lieu of a standard PFC?

you can not tune d-jetro with the power fc software CRD has to tune it with the hand controller i believe. give them a call. i saw him make 30awkw with low mounts and that computer.

interesting

cause nungun has the djetro for a gtr at 1400 with all the map sensors and the standard one at 1100

which would be better on a gtr motor i wonder???

the reason im going for that is i originally had lined up a microtech ltx12 but they where going to custom build one for me with a few extra features such as cdi and more outputs but judging on their previous form i really cant wait a year, so i want to go the PFC DJ because previously i have had some bad experience with my large single turbo and a greedy type r blow off valve of reversion back through the airflow meters.i have tested this and i was seeing voltage swings of up to 3volts in the wrong direction causing over riching issues in between gear changes at medium throttle when the blow off valve was only slightly opening. I believe that running a map sensored computer will eliminate all my reversion problems that why i have choosen it.

My suggestion would always be to use AFM's wherever possible, they are simply the best method for accurately sensing airflow into the engine and therefore tuning it. There are other ways to overcome reversion, for example HKS (and others) make a simple voltage modifier that holds the AFM voltage solid during gearchanges (and sharp back off). Thus the AFM doesn't report the double airflow to the ECU. The HKS unit is called a EIDS (Electronic Idle Stabiliser) they also have a EIDS Pro (Electronic Idle stabiliser Pro) but I haven't seen one of those in operation yet.

Other, more simpler, methods are to use a decent plumb back BOV (such as the standard GTR ones). Generally 50% of the short term richness problem attributed to reversion is really caused by running an atmosphere BOV. And 50% of what's left is due to poor BOV location and operation.

A larger diameter inlet pipe from the AFM to the turbo also helps, as does the longest pipe you can fit.

Apexi's own 1100 ps drag car (VMax) uses AFM's, obviously they could have gone to map sensors if they wanted, but they chose to go for a pair of Q45 AFM's. I am sure they didn't do it for any reason other than it offered a performance advantage. At the very least, it offered no performance dissadvantage.

My 20 cents worth:cheers:

i have the blow off valve set as plum back the problem being the type R only vents or really opens fully about 12-14psi below that i still have the compressor reversion... i will look into these hks units but granted i am chasing big power i dont have an endless financial stream that extends to q45 afms as i have checked and they are around $1100 each new. Previously i had twin rb25 units and i believe i will be pushing them to there limits at around 400rwkw i know i could upgrade to z32 units but again i still have the expense, and the risk of reversion. Another reason i didnt mind going to the map is due to the fact the car wont be driven on the road often and wont encounter the various climatic and load changes that afms are so great at measuring. I understand the apexi drag car runs afms but after talking along time ago with an apexi engineer he mentioned they dont need to worry about the reversion due to the fact the car changes gear so quickly and the fact it is at full load and the blow off valves will always vent the excees air. He basically mentioned there isnt a problem running map as they do on there toyota engines and the reason they run the afms on the apexi gtr car is due to the fact they dont need to tune as often to climatic and altitude changes. Any thoughts???
