Man, what's the problem to calculate it by yourself?

Hi. What points would you choose for this?
Can you show me how you calculate it for that 400kmh?
Sorry, I'm asking because I don't know how that really works

You can divide the range in any way you want, 0, 100, 200, 300, 400 km/h for example, linearly. Effective speed points should be less 4% than displaying speed points. I assume you know how to decrease the value by 4% for each point.

And you need to get data from your cluster and find out how many steps speedometer dial has (this is the last value of motor steps line). So if it's 4740 steps as you've posted above you should calculate middle points (#2, #3 and #4) accordingly your displaying speed points. For point #2, for example:

100 kmh / 400 kmh * 4740 steps = 1185 steps for point #2

Do the same calculation for remaining points #3 (200 km/h) and #4 (300 km/h) and that's all.

Thank you for your reply.
I will test that

I have read out an original GPower Speedometer 400kmh
Car is an M3 E92 Manual 6Speed

Effective Real Speed :
0.0 | 14.0 | 72.0 | 178.0 | 370.0 |

Displaying Speed:
0.0 | 16.0 | 78.0 | 184.0 | 400.0 |

Motorsteps:
0 | 177 | 888 | 2133 | 4622 |

good job buddy! what about acc values?

So 400 km/h isn't real as I guessed before. It's "only" 370...

370 is also OK
