Next Project: GT-R MFD on 370 (oil temp/pressure, boost, etc...)

Excellent work!
Very interested in the development of this.

Keeps getting better!

It took a while, but i finally was able to bring up the nice (GTR) TPMS display and send data to it:



At this point, I have all the screens I wanted (GTR gauges, TPMS and trip computer) and now will start to work on the CAN bus module to send the 370 data to the GTR gauges.

I hope to have an update on this in a few weeks.

February Update:
The first prototype "GTR MFD Converter" board is assembled, wired and programmed!
The first program simply provides the required CAN bus data to make the gauges count from 70 to 120, and then repeat over and over.
This is to verify that the reverse engineering of the gauges is correct... and I'm happy to report it is!!

Note:
Look at the coolant temp (top left), once the temp reached 110C (230F), the entire gauge arc/line turned red... Kind of neat!

Next Steps:
Program the device to read the G37/370 CAN bus data stream, converter the data and send it to the GTR gauges.
I hope to have this done in the next week or so... I just hope it works like I think it should!

Very cool. Always wished Nissan had done this, at least for the 2015 update.

Do any of these have Android auto? I thought about trying to Frankenstein an Altima or Maxima that had them, I believe...

MotorvateDIY

I've had the same thought, but it looks like the newer units with CP/AA won't fit in the dash of the 370.

Your screen mirroring functionality to the aux port probably solves most of the major appeal anyway at least for the simple navigation function.

Here is a short video showing the gauges in operation on the test bench:

Working GTR gauges in the G37!!!
Today was the first in car test of the GTR MFD CAN translator.
It is small device that plugs into the OBD port, and allows 27/28 of the GTR gauges to work on the G37.*

The*one gauge that doesn't work is the "acceleration / braking g sensor", as the G37/370 doesn't have one. I'll look into this once everything else is done.
I did a little extra work to make the (transmission) "Gear" screen/animation work.
That's all for now!

Quick question:
What was the first year the 370 had a USB port and what option did it require?

[update]
From what I saw in the FSMs, it looks like 2010 with Nav has the USB port.
Is this accurate?

MENGXZ

Yes, my Z is a 2010 and it has an USB port.

BTW, how's ur phone screen mirroring thing going on? Really having interest in that one.

In AUS my 2010 Z doesn’t have the USB slot, only the RCA

My AU 2012 does have the USB connection in the centre console. Been using it for various things for ages.
