Review on 🚗 YUGUANG 4" Car HUD Display with OBD2 GPS Dual System - RPM, OverSpeed Warning, Turbine Pressure & More by Tyler Markham

This is the second OBD2 digital instrument. I bought. By far the best digital sensor I've ever seen. I like the lambda air/fuel ratio. It's incredibly accurate and responsive. The only thing I would change is that the rev needle is hard to see. The clock shows 24 hours without the possibility of a 12 hour option. Miles per hour, air/fuel ratio, coolant temperature and volts, which is the only thing that cannot be changed. I want to change the volts to another meter. I promise it's worth the money.
