Tested with a Renault Clio II 1.5 dCi
on the same, short trip multiple times with similar conditions (weather, traffic)
The tests were reproduced later with a different car: Mazda 6 Skyactiv-G145 2.0
➤ Significant differences from the fuel consumption recorded via CAN (and dashboard if it's shown there)
➤ The difference varies in every vehicle
➤ The difference is not constant even for the same vehicle -> Can’t be calibrated.
