With my setup, I have a USB connection for an Ostrich 2.0 (to tune the ECU) and another USB for the data stream for the OBD1 connection. Can't seem to find a reliable Blutooth connection for the OBD1 and apparently tuning an Ostrich through bluetooth isn't reliable due to data dropout.
Not sure if Tunerpro will read data though a single tablet USB port with a hub?
