BMW Sport

to ja się zapytam, w jaki sposób ten program oblicza straty bo w końcu te wykresy to jak rozumiem moc na silniku ??

po dobiciu do określonej prędkości obrotowej (np. 4500obr/min) co na trójce oznacza np. dla mnie jakieś 115km/h puszczamy gaz i auto się toczy do zatrzymania (czy tam minimalnej prędkości obrotowej np. 1500obr/min) - taki pomiar inercyjny jak rozumiem??

no to trzeba dysponować niezłym kawałkiem drogi....

Hi,

You have to start your dyno run from a standstill. This is what I'd do if I didn't have access to the manufacturers data.

My cars rev range is 800-6700rpm.
I'd pick 2nd gear to do the run in, as @ 6700rpm I'll be doing around 57mph.
Set 2000rpm as my minimum speed rpm, though anything from around 1500-3000 would suffice.
Set 6700rpm as my maximum speed rpm, as that's the red-line on my car where the limiter cuts in.
Take the car for a run on a quite road.
*Remember, engine should be up to normal operating temperature.
Take a note of the speed when the rev counter is sitting @ 2000rpm in 2nd gear.
Take a note of the speed when the rev counter is sitting @ 6700rpm in 2nd gear.
Add 2% onto both these figures to account for EU regulations (not sure about 'rest of world').
Input these figures as the min/max speeds, for this example I'll use 18mph & 55mph.
All set to do a run now... Needs to be done from a standstill.
*Remember, A/C off, radio off, all electrics off, traction control off, windows up, etc, etc.
Press Start
When prompted, take off fairly briskly in 1st gear to ensure motion is detected.
As soon as possible, select 2nd gear. Around 10mph (8mph less than the min speed) is a good number.
Floor the accelerator until the red-line is hit, then brake.
You could shift up to 3rd and keep accelerating (as this is mostly always more fun), the app will just ignore any data recorded above 6700rpm

GPS is not used as it is fairly inaccurate over the distances that we are travelling.

Cheers, and have a good day.

JeD Ty jak robiłeś pomiar to GPS miałeś aktywny ? jechałes 1500rpm w programie Start jak się skalibrował to pedał w podłogę tak ?. Ja robie na Spicy 5700 i mam mały problem ... opisz tez swoje ustawienia, ja wpisałem tylko Wage auta i kierowcy, minimum 1500rpm 29km/h i max 8300rpm 150km/h tak jak mam na 3 biegu.
