I haven't really looked at the ones on google play, I've just been trying to figure out what people have been saying on various forums. I can't find a definite answer. Apparently add-on "PID's" can be downloaded which apparently are parameters setup for certain manufacturers. I'm guessing each company has slightly different formulas that decode what the reader retrieves from the ECU. I downloaded the one for Ford but I don't know if it automatically applies itself or if you have to set it up once downloaded. The reading was the same with and without it downloaded. I'm in a loaner Focus right now because my car had rodent damage done to the firewall insulation from sitting on the lot (didn't notice until about a week after I got it home -_-) and I plugged it in and it read perfect. So I don't know what the deal is. I guess I will just TRY to not worry about it, even though I will.
