Review on ACECAR F8 Universal Car HUD Dual System Head Up Display - OBD/GPS 🚗 Speedometer with Brake Test & Overspeed Alarm - HD LCD Refitting Code Table Display by Daniel Mettler

Can't speak to the accuracy but when you look at the real time fuel economy numbers his calculations are quite different from those used to run my car's built in gauges average . 2006 350Z. Wanted it to serve multiple different purposes. Firstly to be able to read and clear ECU codes and also view in real time what I want to know about my car's operation. Economy is inaccurate, RPM lags about a full second, speed lags as well, oil and coolant temps seem pretty close (so I give it a thumbs up). I haven't been able to test the Turbo Boost PSI gauge feature as this project is still about a year away. The price is $90 for its functionality. A bit disappointed, but maybe my expectations were too high. I was using another device that used a Bluetooth connection with my phone. BT was much better in many ways. Blue driver I think. I may need to get another one as I liked the functionality and it gave me a lot of detail to read the code. and I was able to clean up codes efficiently, which this block didn't do. Conclusion: Don't worry about this block.
