Review on 🚗 Autool X50 Plus Car OBD HUD Multi-Function Digital Meter Alarm Speed Water Temp Head Up Display for OBD Driving Computer – Supports 12V OBDII Diesel Vehicles by John Arrow

Not too 'transparent' is a category Revain keeps asking me to rate lol. Super easy to use, plug and play, multiple displays, screens and parameter combinations. I have coolant temp as the main temp (the reason I bought it is to get a closer look at temp), plus voltage and RPM. I can switch between multiple displays, get DSC codes, reset codes and check the engine light, all on the fly. Comes with an OBD2 USB extension cable. Hint: the instructions are awful, but anyone who can turn a knob, press a button, read and extrapolate the meaning of words and numbers can do a lot with this little gem. Use Google, think, and get a meter that gives you real-time performance data. What could be better and all at a very reasonable price. The sensor is configurable for multiple protocols. If you can't manage this, you probably shouldn't be playing with the OBD2 port at first. I personally love it, just wish the case was thinner to have more mounting options.
