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 ?

    • If you are keeping the current calipers you need to keep the current disc as the spacing of the caliper determines the disc diameter. Have you trial fitted the GTS brakes fit on a GTSt hub or is this forward planning? There could be differences in caliper mount spacing, backing plate and even hub shape that could cause an issue.
    • Hi there I have a r33 gts with 4 stud small brakes, I'm going to convert to 5 stud but keep the small brakes, what size rotor would I need?
    • First up, I wouldn't use PID straight up for boost control. There's also other control techniques that can be implemented. And as I said, and you keep missing the point. It's not the ONE thing, it's the wrapping it up together with everything else in the one system that starts to unravel the problem. It's why there are people who can work in a certain field as a generalist, IE a IT person, and then there are specialists. IE, an SQL database specialist. Sure the IT person can build and run a database, and it'll work, however theyll likely never be as good as a specialist.   So, as said, it's not as simple as you're thinking. And yes, there's a limit to the number of everything's in MCUs, and they run out far to freaking fast when you're designing a complex system, which means you have to make compromises. Add to that, you'll have a limited team working on it, so fixing / tweaking some features means some features are a higher priority than others. Add to that, someone might fix a problem around a certain unrelated feature, and that change due to other complexities in the system design, can now cause a new, unforseen bug in something else.   The whole thing is, as said, sometimes split systems can work as good, and if not better. Plus when there's no need to spend $4k on an all in one solution, to meet the needs of a $200 system, maybe don't just spout off things others have said / you've read. There's a lot of misinformation on the internet, including in translated service manuals, and data sheets. Going and doing, so that you know, is better than stating something you read. Stating something that has been read, is about as useful as an engineering graduate, as all they know is what they've read. And trust me, nearly every engineering graduate is useless in the real world. And add to that, if you don't know this stuff, and just have an opinion, maybe accept what people with experience are telling you as information, and don't keep reciting the exact same thing over and over in response.
    • How complicated is PID boost control? To me it really doesn't seem that difficult. I'm not disputing the core assertion (specialization can be better than general purpose solutions), I'm just saying we're 30+ years removed from the days when transistor budgets were in the thousands and we had to hem and haw about whether there's enough ECC DRAM or enough clock cycles or the interrupt handler can respond fast enough to handle another task. I really struggle to see how a Greddy Profec or an HKS EVC7 or whatever else is somehow a far superior solution to what you get in a Haltech Nexus/Elite ECU. I don't see OEMs spending time on dedicated boost control modules in any car I've ever touched. Is there value to separating out a motor controller or engine controller vs an infotainment module? Of course, those are two completely different tasks with highly divergent requirements. The reason why I cite data sheets, service manuals, etc is because as you have clearly suggested I don't know what I'm doing, can't learn how to do anything correctly, and have never actually done anything myself. So when I do offer advice to people I like to use sources that are not just based off of taking my word for it and can be independently verified by others so it's not just my misinterpretation of a primary source.
    • That's awesome, well done! Love all these older Datsun / Nissans so rare now
