R34 Mfd Reset Losing Gauges

Hi All,

I've done a bit of google farming without allot of success, so thought I would throw it to the general forum populous.

I have a R34 GTR V-Spec II. As you're aware, the V-Spec offers a couple of extra features including 2 x extra sensors and the MFD upgraded to utilise these sensors. Namely, they are the Exhaust temp gauge and Intercooler gauge.

My situation is that really I have two problems. The first problem (and if anyone can help with this, great! but it's not the main topic for discussion) is that my boost gauge is registering at 0 at all times, and does not pick up any boost. I had a friend advise me that the MFD needs recalibration, so off I went down the path of recalibrating based on Nissan instructions. The recalibration worked just fine, but it didn't fix anything - and to make matters worse, when I powered the car on after the recalibration I had lost my 2 sensors.

So it would appear that the MFD has reset to a non-V-Spec configuration, and has removed my Exhaust and Intercooler temperature gauges.

Can anyone advise on how to get them back?

As a secondary, does anyone have advice on the boost gauge problem?

I've had the car for nearly 4 months now without fault, so this is the first (and hopefully last???) for a long while I hope. Any advice would be appreciated.

Cheers

its because you ran a diagnostics on the MFD when there was no reading input for exhaust/inlet temp.

drive the car around to get your exhaust temp and your inlet temp up. then run a diagnostics.

it should look like this

if you dont no how to run diagnostics here it is.

Diagnostic mode

1) Turn the key to the "OFF" position

2) Push and hold the joystick

3) Turn the key to the "ON" position while still holding down the joystick

4) Release the joystick at least 1 second after the "GT-R logo" appears.

5) Click the joystick 5 times within the next 3 seconds.

This will show which sensors are functioning and have readings.

Hey mate - spot on, worked a treat.

Thanks for the great advice!

Any guidance on the boost gauge issue constantly showing neutral pressure?

Thanks

do you have any other boost readings in the car apart from the MFD?

if you do, are they all working? or is the MFD the only one with the issue.

thats a bummer, are you running a boost controller!??!?!

all i can say is check your boost sensor in the engine bay. and make sure there are no leaks or anything.

have any tips on where the boost sensor is? the car still boosts fine, it's just the gauge.

if you can give me a hand with letting me know where the things are, i'll get it checked out..

usually on the firewall, up in the corner on the drivers side. little black plastic box about the size of a matchbook. it will have a little rubber vacuum hose running to it, 1 set of wires running out too.

(this is my first GTR had an EVO7 before) oh yeah my car is a R34 gtr Vspec

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
