MFD Upgrade
Yeah the installation is quite easy.
You need to lever the main air vent off from the passenger side, but using a screwdriver and a good cloth or some material. It's really tricky to make sure you dont leave an imprint in the dash, or scratch the vent, but it is possible as I've done it 10 times or so over the last 3 months (explain later)
Once you've got that off you remove 2 screws which hold the shroud for the MFD to the dash. Once those are off the shroud just lifts off (it's hooked at the back). The shrouds off and you need to remove 4 bolt/screws (they are both) and that'll free the whole assembled MFD from the dash.
Of course once you've lossened the unit you'll need to disconnect the cables from behind. This is a little fiddy as there isn't too much cable slack so you've got to wrap your head around the dash to see them
but it's possible.
There's a small locking lug on top of each of the 2 connectors that can be pushed down with a little screwdriver and at the same time wiggle the connectors loose (there's 2)
The whole MFD is out. There's a few screws to remove from the casing (I could explain, but it's really obvious), once you've got these out you can unscrew the 2 boards which need to be replaced.
There are a few ribbon connections, but again common sense will see you get these out and back in with no issues.
Replace the boards, put it all back together again, remembering to run the RS232 cable to the passenger side first, and the lap counter wire / button.........instructions on that are pretty clear (although my lap timer button doesn't work yet) working with DCD to sort that one.
Screw the whole thing back in place and you're sorted..........
Well almost..................my first install was sweet, all worked first time ................for about 45 minutes and whilst I was out driving it just went blank and wouldn't come back to life. Took it out and put the original back, worked OK so put the MFD 2 back in, no go................this went on and on as DCD and myself were trying things out to make it go, but it never did
and ended up having to 2 new boards from Nismo.
All refitted and working OK now though...................3 months later......................delivery is shocking in Japan.
Anyhow once you've got it all fitted mechanically you need to set the thing up. If you don't then you won't have half of the things you normally get on the screen with the horizontal green bars.
Oh yeah............and there's the 2.0 bar boost valve to fit, but that's a piece of cake too, again pictures are good enough to get that done.
Back to the setup.
Don't touch the accelerator........Switch the ignition on..........the screen will display some japanese writing on the left of the screen the only english bit says off............press the joystick in once.............the writing will move to the right of the screen............switch off ignition.
Switch the ignition on whilst holding the joystick in. Release the joystick 1 second after you see the GTR logo, then straight after that press the joystick 5 times in 3 seconds whilst the GTR logo is still displayed.
This should display an accelerator setup box, at this point just push the accelerator back and forth to make sure it's registering properly.
Once that's done, turn off the ignition again.
This time start the car, again holding down the joystick and again pressing it 5 times in 3 seconds. This time you should get a display of all of the functions supported..........eg exhaust temp, oil temp, yaw rate, steering etc.
Some of them will be black and some will be green. The green ones are ones that the MFD is registering an input from. At this point you'll need to go for a drive to get oil temp, water temp etc etc to register. That's why it's important to start the car for this stage.
If you switch the ignition off before they're all green, they simply won't appear on the MFD once it's up and running. it's just blank.
This procedure works for the factory MFD too, I've tried it.
The first time I put in my MFD 2 I didn't let them all go green and turned off the ignition and the MFD only showed oil pressure and intake temp and boost, all the others were missing !!!
Once you've been out for a drive and they all show green. Stop the car, turn off the ignition. Restart the car and you're all done.
You're probably thinking oh my god this guys must have nothing better to write about
but it's taken me 3-4 months to get this far so I hope it helps save you some time.
PS You've got DCD to thank for the setup part..............I got stuck on that too !!!
Thanks
