Honda P28 ECU Tests & MX808S AUTEL Scan Tool OBD1 Live Data

In this video, I performed 3 tests.
Test1:  I connected and tested an old used P28 OBD1 ECU (PCM) to know if it was still working. Test 2: I connected the ECU DATA Link wire and a sensor ground wire to my basic DSO (digital oscilloscope) to know more about the Baud rate DATA transmissions. Test 3: I wanted to access the OBD1 ECU Live DATA with the MaxiCheck MX808S Autel Scan Tool to compare it with my old MD802.
