LCD Gauge Update #3: 35 Data Items on 16 Pages!

SeeThruHead

i think I would only really want a single page.

maybe two large gauges side by side. With 3 smaller gauges to the right and left
total 8 gauges.

Could also have a bar gauge across the bottom. Or some number only gauges in there as well.

I think what would be quite interesting is to be able to set warning values for gauges on the other pages.
So that when a warning value is hit it would maybe flash red and switch to the other page. Then set a warning threshold that when hit would return the system to normal mode and show the default page again.

So many fun things you can do with a programmable screen than just show a set number of gauges on it.



This has almost been pretty cool dash style to me. Theres 4 bar gauges across the top
one on either side of the tach. and 3 number value displays to either side of the tach.

these style gauges are also pretty nice
a gauge around the outside as well as a number value inside


If a touch screen is used you could enable pressing onto a gauge to swap through a list of gauges. rather than swap through full screens. similar to how some physical gauges work with a button to switch value.

these circular displays would be great for this.

Thank you SeeThruHead and redondoaveb for the suggestions and ideas.
I appreciate it!

SeeThruHead:
A display that is "inspired by Motec" could be done down the road. It has a really nice layout!

Also, I have looked into round LCDs displays to replace all of the 370z triple gauges, with any data item you would like.

As I understand it, the factory triple gauges are difficult to remove and installing LCD gauges would not be easy. My first preference is "plug and play" solution as it greatly reduces installation errors. From what I have seen, many don't seem to understand electricity/proper wiring and do silly things.

Right now I need to focus on getting out what I have been working on for the last year: the Bluetooth gauges for Oil pressure, diff oil temp and other CAN bus data for the G37. Since I have easy access to one (my car in the garage), the LCD enclosure is easier to model and to test.

Speaking of testing, we have developed a new add on for the G37.
A manual transmission Gear Position Indicator in the FACTORY cluster:

Plug & Play, Manual Gear Position Indicator for the G37: MotorvateDIY Garage Ep.43

This will be an option in the LCD gauges / mini-dash, or a lower cost stand alone device the size of a small ELM327 and it is plug and play via the OBD port.

I have been driving standard for 40+ years and don't need to know what gear I am in.... However, I sure enjoy seeing the gear number in the factory display!!

One page that could be really neat for track folks is. 4 squares showing tire load on each tire.

Would install 4 linear potentiometers on the cars suspension. connect to your bluetooth server. send values to the display. Set the motion ratio and spring rates for front and rear somehow. And calculate the load for each wheel based on suspension compression.

That's an interesting idea... I would see if a laser-ranging module could be used for suspension travel, much cheaper and easier to install.

Once the gauge development/testing is done, I think the next project it a real time tire surface temperature display using an IR array sensor. Tire temps are a very useful tool to suspension tuning.

For now, my focus are the gauges and a standalone G37 MT6 gear position indicator (displays 1-6 using the factory cluster)

Plug and plug and that slots in front of the dot gauge would be ideal for me. If it was going to have different pages we could go through that would be great (using the stock button for the bonus). I could see 3d printing a bezel and just a friction fit though could see screwing it in later if it was reliable.

Otherwise a 'main page' showing fuel and coolant temp, outside temp and TPMS would probably be my main page.

Something with mpg, range, etc would work too.

Small update:
Wouldn't it be nice to have a "VVEL Gauge" that shows the requested and actual valve lift/duration?
Well, since the ECU controls the VVEL module using a dedicated CAN bus... that got me thinking.

From a past trip to the scrap yard, I have a VVEL module which I wired up to a G37 ECU on my test bench. This allows me to verify wiring and CAN bus IDs by module.
There are just over 1,200 CAN bus messages per second *just* on the VVEL CAN bus, which is a data exchange of about 170,000 bytes per second.

The next step it to record my G37's VVEL CAN bus and then start the reverse engineering!!

NOTES:
• The "ELM327" looking device is the CAN bus to Wifi tool I made.
• I am aware that the typical tuning apps show these values
However, it may be a useful troubleshooting tool as the VVEL CAN bus messages are sent 100 times per second, so you can see everything that is going with quicker updates than an app.
