Attachment 175978 This is the way it is set up from factory, because it starts from -70 Celsius to 133 C and the percentages they have put in you only get the 3 positions.The gauge does not move linear in relation to the percentages either, so 0 percent, 50 percent and 100 % is not quite where you think it would sit.
Attachment 175979 After some reading on discotd5.com I learnt how to change the temperature readings in the header as you can't just click in and change the figure.
I then changed to the temps to readings that suited me.
The percentages are all done by trial, put in a percentage, run out and plug chip in, see where it sits, not where I want it, unplug, back inside reprogramme rinse and repeat. Always chance of damaging pins on chip or socket so had spares on hand. However if I was working with a NNN ecu not much quicker due to the minutes of thumb twiddling as Nanocom backs up/uploads even though no need to physically handle the ecu.
There is some other stuff involved like how to fool the ECU that it is reading the various temps when the car is not running but this is not the tech section.
I am using Tunerpro RT which is free, the XDF files which are needed to show the data in human friendly (non geek) tables are on Offtracks discotd5.com site and can be accessed by receiving a password via email and logging in after making a small donation.
This also enables you to do your own mucking around with fuel tables which is not complicated at all, and you can just load up your original backed up file if you suddenly turn your car into a black smoke belching machine.
You will still need the experienced tuners like Shack and others to sort out the weird niggles (like using oversensitive V8 auto controllers on the td5 !! ) or making fuel tunes for different turbos and other mods etc. but on the whole the basic fuel tuning mods on stock motors anyone can do themselves.
You can PM me if you want these changes done for the temp gauge, no charge, I am an inquisitive owner not a tuner.
