it should be 12v. But if you won't don't connect pin 3 and see if it boots. If not then connect it.

The accessory just turns the GTR badge on the screen, then full boot when ignition. but i am sure you need it to work.

Let me know hey.

Okay I think I have found the problem, seems like removing the cracked laminate from the front of the screen made the screen show totally white. I have ordered a polarized laminate film to replaced the cracked film I had before hopefully it helps the visibility problem I am having. I found a similar problem on gtr.co.uk,

One question I have I am seeing the diagnostic mode sequence on the manual and it shows all 15 sensors that can be monitored, I would really like the oil pressure signal. Has this ever been done or is it on certain model MFDs that this can be accessed? I have a V-Spec MFD BTW and here is the pic in question.

I've just been installing the MFD as of last night - and have a bit of a question:

So far I've only installed the power/acc/ign, 3 gauge cluster wires (illumination/oil temperature/boost) & dash wires (water/oil pressure) - next up is the wires from the ECU (speed, injector duty, revs, throttle position) -- but on doing a test power-up to make sure everything is fine, only water temp seems to be showing up. I've tried running the diags to test sensors, and even then whilst it seems to detect sensors, nothing is really coming up besides water temp - boost just sits at 0. I've checked, double-checked, and triple checked the conncetions. Does anyone know if this is normal?

I'm wondering if maybe it's needing the inj/speed/throttle sensors from the ECU before it'll initialise the other sensors properly? I'm hoping that's the case anyway. Ah well, I guess I'll put in the remainder of the ECU wiring and see what happens. Otherwise, I'll be trying to track down whether it's a grounding problem or something else weird.

Fingers crossed this unit isnt a dud (it came from a working car) - I can't imagine how much it would cost to repair :P

Well - that solves that - and is a warning / informational thing for anyone else wiring one of these up - your sensors, etc won't display properly until the ECU sensors are all hooked up too (injector/throttle/speed/rpm).

MFD is now working beautifully :(

If you follow the wiring diagram that Purpleline made. The one i put the link to then your oil pressure sensor will be detected. But the only way to have it on the display is to buy the Nismo upgrade at about $900 to $1400 and this will then give you upgraded Boost to 2BAR and replace throttle position with Oil pressure.

Also adds the G meter lap time and data logger etc. (these only work in GTR)

Check it out here.

Does anyone have the wiring for the Intake and EXT sensors for the MFD. I have the Intake sensor and the EXT on order and as I have the Vspec model I have access to them. Just need to have both wired to have them functionable on the MFD unit. Thanks and also got my MFD working proper so weekend it is going in and also going to have the wires for the EXT and Intake run as well.

Why do you say it will only work in a GTR?

The lap timer is only a switch button to add, data logger comes with the kit.

The thing I would like to know is the G meter working in a GTT with the nismo kit?

Anyway thanks for the post it helped me when I was stuck with the yellow error message (it was because I haven't wired the ACC +. The screen displays exactly the same message when the ignition is not on and when you press a button)

it wasnt easy, we were a bit confused when we 1st wired it up and got this error message.

we still dont know wat it means but we gave every input a extra shove

and...... it worked =D

A question for those who have done it - how has anyone hooked up the GTR intake sensor on the GTR?

It doesn't use a bung as in the exhaust temperature sensor, it screws in - which leaves me wondering how you would mount this up, and especially in such a way that it seals it up against pressure leaks, etc.

Very interested to hear back from those who have done it ....

MFD is now working beautifully :)

Lol I just freaked out tonight, thinking my MFD unit is stuffed, when my boost stays at 0, but it made me feel better after reading what you said, so now I'll wire up the ECU tomorrow and see how that goes :)

Hey guys, I've just hooked up my MFD, but I have a question, how come it only picked up the first 4 sensors? Boost, throttle, oil temp and water temp? It doesn't say it picked up the other sensors, but I know my rev light works. Because isn't there like 15 sensors all up? Including some GTR ones (I know I won't get int and ext temp), but others. Cheers!

Alright, finally done.

It took me a couple of days per my battery dying and a couple blown fuses. I received a lot of help from a dude named Dan on GTROC:

and a dude named Bala from Malaysia:

I didn't want the whole install to be very messy so I bought some items from a local electronics store and a Radio Shack.

I plugged the wires into 4 (male/female) harness endings after I tested the MFD.

I don't have a picture of the functioning MFD but you get the idea. I tapped into the wires that the MFD needed to function properly and labelled them as well.

A few sensors still aren't working. For example, my MFD isn't reading INJECTOR but my Apex AVC-R is. Ironically, they're both plugged into the SAME ECU wire. I'll assess that some other weekend.

What sort of a stupid comment is that :rolleyes:

I know for my own MFD install it was a case of either:

i) find an electronic device that displayed multiple gauges. A few options here none of them particularly cheap. Still left with triple gauge cluster - what's the point?

ii) Replace triple gauges, install additional gauges to try and get a good idea of what's going on

iii) Simply just install an MFD - a device which hooks up perfectly, doesnt cost the earth, isn't defectable and displays multiple gauges without any dramas.

Seems like a pretty obvious choice to me. Feel free to explain why you feel so strongly about this view.

    • Huh, wonder why it blew then. I never really beat on the car THAT hard lol I dailyed it and the turbo blew after 6 months
    • That's odd, it works fine here. Try loading it on a different device or browser? It's Jack Phillips JDM, a Skyline wrecker in Victoria. Not the cheapest, but I have found them helpful to find obscure parts in AU. https://jpjdm.com/shop/index.php
    • Yeah. I second all of the above. The only way to see that sort of voltage is if something is generating it as a side effect of being f**ked up. The other thing you could do would be to put a load onto that 30V terminal, something like a brakelamp globe. See if it pulls the voltage away comepletely or if some or all of it stays there while loaded. Will give you something of an idea about how much danger it could cause.
    • I would say, you've got one hell of an underlying issue there. You're saying, coils were fully unplugged, and the fuse to that circuit was unplugged, and you measured 30v? Either something is giving you some WILD EMI, and that's an induced voltage, OR something is managing to backfeed, AND that something has problems. It could be something like the ECU if it takes power from there, and also gets power from another source IF there's an internal issue in the ECU. The way to check would be pull that fuse, unplug the coils, and then probe the ECU pins. However it could be something else doing it. Additionally, if it is something wired in, and that something is pulsing, IE a PWM circuit and it's an inductive load and doesnt have proper flyback protection, that would also do it. A possibility would be if you have something like a PWM fuel pump, it might be giving flyback voltages (dangerous to stuff!). I'd put the circuit back into its "broken" state, confirm the weird voltage is back, and then one by one unplug devices until that voltage disappears. That's a quick way to find an associated device. Otherwise I'd need to look at the wiring diagrams, and then understand any electrical mods done.   But you really should not be seeing the above issue, and really, it's indicating something is failing, and possibly why the fuse blew to begin with.
