Speed overreporting seems to affect reference consumption calculation incorrectly

There seems to be a glitch in the OBD data reported by the Volkswagen ID.4 (and perhaps other MEB platform cars) that leads to the car erroneously reporting its speed under certain circumstances (CarScanner reports "158.45 mph", which appears to be a conversion of 255 km/h - presumably "255" being a sentinel value that the information is invalid). This seems to lead to ABRP thinking the speed is being overreported by the car by a large margin (see screenshot), which is also leading to large errors in estimating the vehicle's energy consumption; ABRP is currently estimating my car's consumption is 2.71 mi/kWh at 65 mph, leading to incorrect range estimation.

Hi, 4.4.4 is out for a few days now. Could you please reset reference consumption in car details and check if it works correct now? Thanks!

My car (2021 RWD) is on the U.S. 3.1.0 update.

Hi Chris, could you please check which firmware your car is running?
For now we added a speed validation, we have to check that in detail with a real car sometime later to see whats going on.
The speed validation will be released with the ABRP 4.4.4 in a few days.
