Hello, I need some help! I managed to connect to an arduino Uno, I can see most of the readings, but my car only displays the MAF, Spark Advance and TPS sensors via obd2 request. For example, if I connect an LM327, it opens the frame and shows me the value. Could I do this directly on the arduino? Ask the car to show me this value and then configure it in my xml?
Possible, yes. But are you sure you really need to make your own OBD2 adapter as there is so many reliable and relatively cheap adapters around?

Can you recommend one that is wired and that I can map all the information such as turn signals, headlights and open doors? Bluetooth connection has a lot of delay.
In this case, I use Arduino, but I just need to open the request to get some information through Arduino.
Iād recommend OBDLink SX USB adapter.
