GTR M.F.D. into R34 GTT

[Marky B]

Hi guys, been on the forum for quite some time but never really posted as i tend to be a bit more active on and English one... however i found this forum has loads of great technical info.

 

I finally had a weekend free to put a GTR M.F.D. into my R34 GTT

 

Overall went fairly well.... wondering if anyone else has done this before as I have 2 issues.

 

1. the cover that goes over the unit sticks up at the back (near the windscreen) and won't sit flush with the dash. Does it need to be modified to fit or am I missing something.

 

2. It doesn't seem to be picking up a reading from oil temp or water temp sensors. Anyone have any advice on why or how to fix. The oil temp reading is currently wired into what used to be the triple gauge meter for it and the water temp is wired off the back if the Speedo gauge (as per attached wiring diagram) but no readings from either.

 

I know a few people on here have done this mod so....

 

Any suggestions??

 

Thanks!!!

You can ignore this..... bit of a rookie mistake they are working it's just fluids weren't warm enough to register.

I'll see myself out

Good to hear you got it going.

That diagram is helpful, did you have any other documentation that you used to install it?

Thanks

I had a blown up pin diagram of the ecu.

I plan to.make a how to guide with photos I was going to post on the forum

Good to see it worked I have also just finished putting one in my gtt and it looks nice..

About the cover not sitting flush with dash I personally think that it is supposed to be like that. If you follow the top side edge line of the cover you will find that it lines up with the dash.

Unless the cut on the dash is slightly different as to the GTR ??

Did you get the intake temp going on the screen?

[Marky B]

I don't have a v-spec MFD so mine doesn't have intake gauges

I can help you get the mfd pick up intake and exhaust display. Since you don't have the sensors it won't display values but you will have 7 rows of display.

[Marky B]

I wired the ambient into one or both of those from I think so they should display that, didn't realise there were on there though, how would you do that then?

[Shamir]

Yes that's pretty much what needs to be done .
I first connected the AMB to the intake sensor and ran the diagnostic mode it shows that it had the sensor registered but wouldn't show in the display. Then I connected the same AMB to exhaust temp and ran the diagnostic mode it registered the exhaust temp as well and then finally both the intake and exhaust temp display was showing. Hope that helps

I'll give that a go when I get the car back it's getting upgraded and mapped atm

Cheers for this. Got it all working spot on now!

Great.

Is there a link that is posted that shows a step by step wiring installation of this? Need help! 
thanks
