can you display other parameters like MPG, DEF levels etc?

it's possible to calculate MPG but might not accurate, for DEF levels. I'm not sure if there is support PID or not. if it's available , we can display DEF level on guage.

Great code. Do you mind helping me to modify your code to choose a specific header for each pid? Ex: coolant goes for PID 0105 at header 7E0, but CVT transmission temperature (in a suberu vehicle) goes for PID 2210D2 but at header E71.

I have finally figured out which is the PID for my 2016 Subaru Forester CVT Temp (2210D2) but it comes from the TCU (7E1 address, usually the pids come from 7E0). I managed to test is using car scanner terminal and it works. I found where to edit the standard pids in your code but haven't managed to change where the pids come from, by default they come from 7E0, but in order to read my CVT temp i have to change it to 7E1, is it possible to change the module address?

@vacob6494 2 ай бұрын

I'm not sure about the ECU address but from this page. obd2australia.com.au/auto-transmission-temperature-pids/ subaru and ford TFT has the same ECU address but different pid, I'd like u to try 221017 and see if it works, by the way you can read data from ECU address too, please read this datasheet www.elmelectronics.com/DSheets/ELM327DSH.pdf on page 39 and 47. (recommend true ELM327 adaptor, not cheap one) please remember that you need to correct calculate formula to give the correct temperature.

@MateusLeonardoMendes 2 ай бұрын

@@vacob6494 Thanks for your attention. I tried 221017 before, does not work. 2210D2 I'm 100% sure it works because I successfully got the temperature from it by adding a custom sensor in CarScanner app, but I had to use the header 7E1 instead of default 7E0. If you give no instructions to Elm327, it will always go for the default header (7E0), so it all your needs are standard PIDs, there no need to worry about the headers. But in my case I need to go for the 7E0 so I have to figure a way to change that
