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

SeeThruHead

It would be pretty cool as a replacement for the 370z left circle display.

You could even make the graphics looks like that old screen.
And since you have the data you could replace the fuel bar and temp bar with higher resolution bars on your screen. Maybe make it easily removable if the user has to access the original lcd for some reason.



Just cover this right up and put a much more useful display there.
I would definitely buy one.

with a display like this maybe?

that would be the definition of OEM plus. and unobtrusive upgrade.

Thanks for this suggestion! I really like that idea.

370 gauge clusters are expensive at more than $220 Canadian. I can get a G37 cluster for about $50 at the local scrap yard... I guess that is the "Z tax"

To start, I like the idea of something external (that doesn't look like an add-on) that I can use to test/prove the durability of the hardware and software in different operating conditions. If something does fail or act weird, it is an easy replacement.

Once the durability is proven, I will buy a 370 cluster and see how this could work.
If you have any other suggestions, please keep them coming

THE BULL

I have 3 of these clusters at the house and they sure are expensive. From taking them apart I can't see a passive way to install, almost 90% sure printing it would be the only option.

What I do envision is this going in the center storage (where non navi install their tablets)

This LCD gauge will be a hot item for sure!

I'd replace my 4 gauges with Frank's screen and install it in the cubby area again

For your gauges, is this correct?
• Boost
• Oil Pressure
• Oil Temp
• Air/Fuel ratio
• Ethanol content

Are they all standalone gauges & sensors?

redondoaveb

All correct except water temp instead of oil temp. All standalone

Really enjoying seeing your progress on this project! Just to clarify, engine oil pressure is NOT on the CAN bus, right? Just a low oil pressure switch. Which aftermarket oil pressure sensor are you using that can send data to the bluetooth sensor server?

I'm glad you have been following the progress. It has evolved into much more than I expected when I first started on it just over a year ago.

Correct, engine oil pressure is not on the CAN bus.

I am using a 150 PSI Honeywell PX3 pressure sensor for oil pressure and a 100 PSI PX3 for fuel pressure.

The Bluetooth sensor server will work with any 5v, 3 wire pressure sensor. They typically output 0.5 volts at 0 psi and 4.5 volts at the max rated pressure.
It does the analog to digital conversion, applies the scale and offset, then sends the data out via Bluetooth.

Hey BULL, it was nice to chat yesterday.
Thanks for the offer to send me some pics of the disassembled 370 cluster. That will allow me to see inside the cluster without buying one. (for now!)
