The RealDash trip is faster than the original dashboard

I have already configured the wheel diameter, tire, rim, engine, weight, gearbox, fuel, and increased the wheel and tire sizes, but I still can’t get the trip to match the car’s dashboard.

Note: the data is being captured by the OBD2 port’s network. I am using the ECU to measure speed. If anyone can help, I would be grateful.

All distances are calculated from vehicle speed. Typically speed info from ECU is ‘real’ speed of the vehicle. Car’s instruments are mandated by regulations to show 3-10% more than actual speed. That could be the reason tripmeters in RealDash increase ‘slower’ than tripmeter in your car’s instruments.
