Fwiw the mapping is corrected in both the ECU and the gauge itself, but I seem to have got it sorted, I really think it's a very niche modification that won't catch on, but just thought I'd ask.

I think it'd be a good modification, either separate from, or as part of your " better than others" complete tune package.

Literally off the back of an envelope, my opinion only and obviously not linear, but having the similar middle ground, but not getting there until 75 degrees instead of 70 would allow some to pick up a stuck open thermostat ( a large number when they start to fail hang around 71-72 degrees), which remains unobserved without Nanocom etc.

Thanks for that, you better patent that envelope before I steal it!

Yeah I was thinking to maybe have the gauge a "little bit" corrected still.

It'll take a number of changes to make it work reliably.

Too late, I've already got a stamp on it

From what Sierrafery says,the OEM guage on D2 TD5 sits at the center of the guage from 70 to 119 degrees,then at 120 degrees,goes into the red.

Seems a stupid idea to me,it should gradually creep up to the red,from the center,as the temperature gets hotter.
