R34 Gtr Mfd In Gtt

[99 GTT]

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.

[TriniGT]

Okay I got it powered up when I powered pin 123 and 12 and also grounded 13 and 14 but the screen is very bright, so bright that I cannot see anything. When I look at it from the side I can barely see the screen. Any suggestions?

[gfunkk]

this is awesome, i wanna see how the unit fits in a BNR32

[99 GTT]

Press the DISP button and adjust the brightness.. Should be low to start with unless the screen has a problem.

Would it start up without pin 3 connected??

[TriniGT]

I think it need the ACC to get it started as with just 1 and 2 it was a no go but then I connected 12 and 3 and it worked. Will check and see if with 12 alone connected if it made a difference. Gonna fiddle with it tonight again.

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

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.

Sounds like I will have to run an EXT and Oil Pressure on my A-Pillar. I have located an intake sensor off a GTR intercooler.

[TriniGT]

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

[jrm]

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 ....

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

[Charles89]

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!

subscribed. I have a MFD inbound for my GTT.

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 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.

Take the MFD out of the GTT is doesnt belong , belongs in GTR

[jrm]

What sort of a stupid comment is that

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.
