Re: Anyone running Android OBDII Apps - Torquepro etc.?
a) The PCM is a computer and a not-very-fast one (anyone know what it is e.q. Motorolla, Hitachi, etc.)
b) OBD-II is a serial data stream, Chrysler uses ISO 9141-2 which has a 10.4 kbaud (~56,000b/s about the same as a high speed phone modem on its best day. In comparison my cable signal to the house is 45 Mb/s ). May be slow to some but beats rolling a Brush recorder chart down a long hallway six ways from Sunday.
c) I think the steady O2 reading is really the one downstream of the cat (bank X sensor 2). It is supposed to measure the efficiency of the cat and once the cat lights off, it shouldn't vary much from .5v.
d) For Android the best home choice is Torque Pro hands down. Lots of add-ons. If you use Windows or iOS, I use TouchScan which is available for all three. If you want to get serious about it, AutoEnginuity will set you back $500 with the Chrysler add-on but if you need to see the HVAC blend door operation, that's the way to go.
e) for $11, I just leave BT dongles in my cars, saves fumbling around.
f) More than you wanted to know.
