A BMW equipped with an 8HP automatic transmission was programmed using xHP Flashtool. The video shows a Stage 3 flash followed by a road test. The specific BMW model and year are not identified.

In D mode, the gear display showed the current gear. During the demonstration, the transmission was in fifth gear at about 60 km/h and seventh at around 71–72 km/h. The driver described the shifts as quicker and smoother.

The video also mentions a potential fuel-consumption reduction of up to about 0.5 L/100 km with calm driving. Fuel use was not measured before and after programming on this car, so this remains a possible benefit rather than a verified result.
