Hi all , I went to plug the new Datalogit kit int my PFC and find that it wont plug in . The male plugs on the extension cable and the black box have plastic guide pegs that are too long/wide to fit in the PFC boxes socket .

The Apexi Commander's plug fits fine and when compared the difference is very obvious .

Surely to christ I'm not expected to break the plastic pegs out of these male plugs to get them to fit the PFC's socket ?

I have a home made extension cable made from a 6 pin din plug that's had the 6th pin and the plastic peg removed and yes I made sure it haden't lost any pins in the PFC's socket .

Does everyone attack these male plugs or is it just mine that have a problem .

Cheers A .

Upon closer inspection the supplied datalogit plugs seem to have the plastic pegs in the wrong place , they look like generic 6 pin din plugs but with only 5 pins .

The PFC unit and the Apexi Commander must have a slightly different version of a "Din Plug" system because their plugs have the plastic peg offset downwards towards the dimple that lines up with the small square hole at the base of the socket .

BINGO - just sussed it out !

Whilst glancing at my old dinosaur laptop I spied a "Din" socket on the back of it . Methinks I wonder if the Datalogit plug or the supplied extension cable fits in there - which of course they didn't ...

Then brain drops into gear and remembers that computers don't use Din sockets - they use PS2 sockets .

I just happened to have an old PS2/USB adapter plug within reach and gess what , it fits the lap tops port and looks just like the Apexi Commanders plug - only 6 pins instead of 5 .

The burning question seems to be why would FC Datalogit supply the gear with Din plugs when the Power FC's socket and the Commanders male plug are PS2 plugs - minus one pine ie 5 ?

I really hope someone thats been around these Apexi Power FC's , like Paul33 , can shed some light on this issue .

Lastly one for the computer hardware nuts , is there such a thing as a 6 pin Din/PS2 adapter plug available because that would adapt me from PS2 to Din and solve the problem .

I should NOT have to break the plastic lugs from the Datalogit plugs to make them work , they should be the correct type .

The silence is deffening , cheers Adrian .

PS Have a look at plugs C and D - note the lug in the middle of the plug diagrams . This is why the "5 Pin mini DIN" wont fit in a "6 pin mini DIN socket even without the 6th pin .

5 pin and 6 pin . The size and the offset of the "middle" peg .

well, i can help with my solution. my datalogit fitted the pfc tight but OK, but the ps2 cable I used to extend it required a small cutting of the middle peg.

it is important that the fittings are very tight.....a loose cable will cause intermittent loss of power in the ecu even though it is only running a hand controller or datalogit

I'm not sure if I posted this but I did eventually get the supplied extension cord to fit under duress into my PFC's socket .

I hate to admit I guttsed it but with a few prayers it did go in - it's just a whole lot tighter than it should be .

The risk here is pushing the plug so hard that the socket in the PFC could break its mount and fall inside the box .

I think the the bastards at Apexi don't use an industry standard 5 pin mini DIN socket , their rectangular hole for the plastic guide peg is smaller than a std 5 pin mini DINs peg .

They possibly realised that 5 and 6 pin mini DIN plugs and sockets are very similar , all thats different is the 6th pin and the plastic guide peg/hole .

Apexi's is basically a std 5 pin with a "custom" smaller guide peg hole to suit the commanders plug - which has a real skinny non standard plastic guide pin .

Anyway the extension cord lives in the car and runs behind the carpet and under the edge of the console out of sight so that the black box and laptop can easily reach from the co pilots seat .

I now need to nut out the software and interface the Tech Edge WB02 and start tuning .

Going to be different working with MAF rather than MAP like the old Haltech and Autronic computers I had used .

Cheers A .

PS Also now in the Yahoo users group and have posted asking why some MAF Toyotas have a "base " AFR fuel table as well as the usual fueling table . Why doesn't the Nissan FC Logit software have this feature ?

      Thanks for all the replies fellas. Gonna finish putting it back together and see how it handles the set up. If it starts pinging it’ll be parked.

      Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).

      Yuh, if it's 45°C outside, my car is driving in it.

      I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating.

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
