I took my car out for the first time since November as the snow is now gone.
I made this change over the winter with a unit I picked up from an 05 off eBay.
After installing it I remembered that my car is Canadian and reads in kilometres, not miles(senior moment). Even though the meter says miles it does still read in kilometres, so all is well!
Interesting. I hadn't considered that at all. I appears that the Canadian part is actually different, I would have assumed there was just one part and the LEDs would exist for both kilometres and miles. I guess the distance to empty, speedo, and fuel economy displays all look funny because they're still displaying metric units with mismatched imperial units.

I had the Z out this weekend and put on about 100 KMS , approx 60 miles.
The speedo displayed in KMS, I averaged around 120 on the highway, slower around town (obviously). It appears it displays fuel mileage in mph. Before I changed the gauges I was using 9-10 litres/100 KMS.
So it appears it displays speed in metric, mileage in imperial, and DTE in miles. Go figure!
I've got a 2007 350z Roadster, and it always bothered me that Nissan did away with the individual tire pressure readout on the trip computer on the center triple gauge. The idiot light sucks because I'd really like to know if I have 28 pounds in a tire, or if it's like 15 psi... there's a big difference in needing to air up when and where it's convenient, or to fix it immediately. It also sucks to have to check all four tires because the idiot light doesn't tell which one is low. I knew the pressures were available, because I can pull them up on my laptop with my Consult-III.
I did a bit of research and found that the TPMS sensors talk to the keyless entry receiver, that in turn talks to the BCM, which is connected to the A/C amp, which talks to the cluster, which is finally connected to the center triple gauge. The BCM is the only year specific part in the system, AFAIK. People have swapped in the console and center dash from 06-08 models into their earlier Zs, and the required A/C amp for the new climate controls plays nice with everything. I saw that one person that did the swap and lost the TPMS display because he used 2008 center gauges... and that he swapped them back out for his older set.
This got me thinking about going the other way. I swapped in a set of center gauges from a 2005 Touring model, and now have access to individual tire pressures on my 2007 350z. This is plug and play, and looks to work exactly as expected. I think the pressure display is simply disabled in software on the 07-09 trip computer, because the "PSI" led is there, you just can't switch to that mode on the factory trip computer.
I got mine on ebay for a little less than $60, I could have saved a few bucks, but the seller had the VIN listed and I wanted to make sure I got one old enough to have the TPMS functionality. In hindsight, the older style with TPMS readout have a sticker that says CD000M0, whereas the 2007-2009 is EV00A. The plastic lens is held on by a couple of phillips head screws, so one could save a few more dollars buying one with a hazed over scratched up lens and swapping that part out.
TLDR: If you want individual TPMS pressure readout on your 2007-09 Z, just swap out the center gauges with a set from 2003-2006(I went with 2005 just to be sure).
You are the efffen man!!! I was just about to do this until you figured it out. You found out the cluster and I found the 370z steering wheel lolBtw were you able to fix the rpm since the old clusters were set to 6800? If so how?

The RPM is adjustable with the buttons on the side of the main cluster. I was able to set mine to 7,500 rpm, I think it went higher as well, but defaulted to 6,800 when first powered up. It retains whatever you set it at after killing the ignition. My replacement center gauges were from a 2005 350Z fwiw.

I see. Once my 06 gauge comes in I'll play with it to see if the RPM will change. Thanks bro
Bumping a good idea in case anyone else wants to try it.
I bought 2005 gauges off Ebay and everything sees to work just fine.
Super Easy
- pop the stick shift trim to expose 2 screws
- unscrew the screws... hardest part... don't drop them in...
- pop off cubby and gauge trim
- unplug gauges
- 2 more screws to remove gauges from trim
- optional 2 more screws f you want to swap clear lenses
Reverse process.
Can you refer me to where I can read about how to reset the tpms warning lights and I had changed the custom steering wheel to factory, and air bag s till on
If you messed with an airbag or any part of the SRS system without 1st disconnecting the battery, you may need a high end scan tool to clear the SRS codes that have been set. For something simple like an impact sensor not reporting in, just replacing the sensor should resolve the fault. However if the vehicle was in an accident where an airbag was deployed, then a hard code is set and stored in the SRS module, these cannot be reset with an OBD tool. You will have to pull out the SRS module and send it off for this level of re-programming. There are plenty of businesses who advertise this service online.
Does your factory wheel have an OEM airbag? Is it properly connected? Have you tried scanning the vehicle to pull the SRS codes? It is possible that the SRS light is on for a different component within the system (For example: seat belt buckle sensors, seat weight sensor, impact sensors).
