I would just pick up a cheap android phone
get the app called torque
and buy a 15 dollar bluetooth obd2 reader from meritline
shows a lot of car info real time
does 0-60 times and can check for fault codes
there is am ios equivalent but I cant remember the name
that and ios doesnt like to connect to bluetooth or wifi obd2 readers
you have to be jailbroken and a whole bunch of other steps
