has anyone here used the scanner that harbor freight sells? i don't have the phones that some have talked about, but i do have an android tablet and a chromebook that maybe could be used with one of those bluetooth devices. what ones are good but not real costly? i have a scan gage 2 but that for some reason never connects for scans but i do get the other data. everytime i connect it and go to the scan section it says not connected, so i just use it for the mpg and other data and just find another one for obd2 scans. and that way i can leave the scan gage 2 connected in my car all the time.
