KONNWEI KW850 vs. KW310 vs. KW350: Detailed Comparison
Key Things in Common
These OBD2 scan tools share some common features. Functionally, they all support live data, read and erase codes, freeze frames, handle O2 sensor data, EVAP tests, and provide vehicle information.
In addition, these three KONNWEI scanners are OBDII-compliant. Concerning hybrid or electric cars, all the three are not compatible.
The inner engineering – Design aspects
The KW850 stands a notch above in terms of design aspects. Apart from the standard features expected from the car code scanners, KONNWEI KW850 hosts an RGB color screen with 4 live graphical readings. The Model 6 onboard monitoring function indicates which cylinder has failed and has the inbuilt intelligence which handles the software updates on its own to give some samples. It also allows switching off the malfunction indicator lamp and is embedded with 8000 codes.
KONNWEI KW350 ranks high on another aspect because its design ensures that any faults in the safety restraint system, Anti brake system, the tire pressure monitoring system, or the steering angle sensor catch your eye, but that is for V/A vehicles alone. It also supports automatic software updates.
