Nice R&D :)
You need a neater all in one solution for your temp gauges, wouldn't be hard to connect all the sensors to an arduino clone (cheaper) and display them on a small screen.

sounds like you're talking yourself into a job ;)
As it happens I do have some spare arduino boards and an lcd lying around. What voltages do the sensors work on, or have you got a link to a datasheet?
Yes that would save any messing with converting voltages.
The lcd is only 2.4 inches same as my data display project (ignore how slow the refresh is, I have a faster processor on it now, just need to do another video):

A 7" display might need a different arduino (more connections) to run but it's not impossible to do. Other ways to do it are to use an arduino to process the signals from the sensors and output the data to a raspberry pi to do the data display stuff as the pi has video outputs.
I've just bought a starter kit and a pack of assorted sensors to have a play with, more for front splitter and rear wing control, I think it's time I made some sort of effort to learn this stuff, but would love for you to make me some sort of display for the temp sensors.
Cool, if you check out banggood.com they have loads of arduino prototyping boards and the like cheaper than you can get them here in the uk, they're good for playing with. I have a test board setup on a bit of perspex with a breadboard stuck next to it for mocking things up and testing code. It's only basic but it does what I need it to.
Would the 2.4 inch screen be ok for your temps gauge?
2.4" screen would fit in the air vent quite nicely, perhaps 4 bar graphs instead of numbers as a quick visual display?
Just been looking at the nextion displays, absolutely perfect for the T-10 dashboard, either one big 7" screen or maybe two 3.5" screens to display each engine and a small 2.4" for the speedo
Did some quick code for the temperature display. And since it was raining I thought I'd fit it in the vent so you can get an idea of what it would be like (colours are a bit washed out in the pic but are really nice in reality)

I like the nextion stuff, too expensive for me though. Plus I like the challenge of making it myself.
I've got some spare clocks and was looking the other day at how I could fit an lcd into them
that looks fantastic
I with Colin on that, your really getting the hang of this dash stuff
They do look ok but still missing that wow factor, they're functional enough at the moment.
I had to upgrade to a different processor for my display as it has to deal with all the converting of the streamed data from the ecu (some 40 odd variables) and some of those include division which eats processing power. I'm trying to get a video of it working but Mrs Dave has trouble keeping the camera still when I'm driving.
Anyway, I digress....
Now starts the slippery slope into the unknown.

You'll master it, I'm sure of that....:)
small update on my temp monitoring, airbox temp definitely has no effect on intake temps, BUT engine bay temps really do, on the open road with ambient at 15 degrees, the intake temp will be around 20 degrees, (with engine bay temp at around 20 degrees) In traffic the bay temps can climb over 60 degrees and the air going into the charge cooler can climb from 30 to 40 degrees and intake temps will rise to 25 degrees. once on the open road the temps come down again.
if you do, please remember to put safety overrides into the system. Mate had the keyfob start on his VW van, didn't fit the switch to stop it from starting if it was left in gear. Did exactly that, started in gear & being a diesel had the torque to actually start the engine. He jumped in front to try & stop it, ended up with a titanium bar in his leg after being crushed between the van & a house
Small update on the T-5R, time for a wheel change,
But which one to choose?

I've decided to have the flat bottom one on the T-5R and the Alcantara on the T-10

Still waiting for some Volvo badges to replace the Jaguar ones and I've started on a mold to make some carbon fiber centers for both wheels.
