Im try diagnostic but doesn't work... Im test a lot of diferent applications but all doesn't show right values...
Only thing which is useable is rpm if you write your own application which don't divide value which you read with 4 like all aplication... speed is not useable because when you are in "stop position" you get 0km/h and when you moving you get 255km/h. you can use code reader/delete too. Maybe you can use throtle % and MAF too but I don't remember... I will sell my device... and this is not problem of OBD device because Im test car with other OBD device(VAG-COM) and is same, so I think car is not full EOBD or OBD2 compatible...
