4622

Ok, so the middle point on M3 gauge is between 120 and 150 - 135 km/h, so from 135 to 330 the needle goes a half of the dial - (4622 / 2) = 2311 steps for (330 - 135) = 195 km/h.

2311 / 195 = 11,85 steps/km for the second half of the dial. Also the same value we have for 120 to 135 km/h range, because there is the same markup step.

Based on this we can get amount of steps for 120-330 km/h and it's 210 * 11,85 = 2489 steps. The remaining 2133 steps are for 0-120 km/h meaning 17,775 steps/km like you you've calculated. So you were close, actually.

Hey mate, the last calculation worked. But now I'm confused. If the speed dial is linear. I just gave to calculate the steps for (km/h / max amount of steps), right?

Effective speed:

0.0 / 13.0 / 52.0 / 120.0 / 300.0

Motor steps:

0 / 200 / 800 / 1484 / 4622 should be right?

Calculated 15.40 steps per kmh. So I can use this value to calculate all 4 points by calculating:
13*14,40 = 200
52*14,50= 800
120*14,50=1484
300*14,50=4622


But if I measure the cluster speed with gps app it's always 4-5 kmh off. The faster I drive, the bigger the difference becomes.  Any bad calculation?

EDIT:

With oem coded cluster to 280 the GPS also shows a difference from 5 km/h. I guess it's like a tolerance?

But still too much difference on the calculated cluster.

You're right about tolerance, but did you set the same values for effective and displaying speeds?

Yes i did, should i calculate the tolerance ? So for display speed 5 km/h higher than the real speed ?

It's up to you if you need real or speed with tolerance. I'm not quite sure about how it works, because there's also a coding flag BC_V_KORREKTUR for tolerance, which you can change using NCS. I assume this param just switch between effective/displaying scales, but maybe it works in a different way.

Yeah, just leave it as it is...

Is there a way i can adjust the starting point of the needles ? Setting them manually by hand is such a pain lol

With "start position offset", but that´s just to correct the position a little bit, not for big corrections

Hi anyome have the default setting for Perfect ToolBox for instrument cluster  bmw e90 lCI 260kmh and 5500rpm Diesel High Cluster...
I have swap the cluster foil faces from mpg to kmh diesel

I need for the tachometer and speedmeter
 I have try it from google but the rpm are not the same,.. and need the default one..thanks

Will send you downloadlink as PM.

Hello again, i have replace my face dials with one with 330kmh, do you have the default perfekt toolbox settings? I have try many from the google but the nothing works and the speedmeter is not correct when i press test with ( Perfekt Toolbox) at 100kmh shows 80kmh...

My car is bmw e90 lci 320d 184cp

THANKS

There never was an diesel with speedo up to 330kmh so there are no default settings. I have done it on e92 330i or 335i I don´t remember. He put speedometer from M3 E9x.

It is better to try a real test instead of toolbox test. If the dial layout is not linear, the test won't work correctly.

Yes please send  me your setting to test it Thanks
