Your speedometer arrow motor still has 7153 steps to max position (physically). Those steps points reflect how many steps the motor has to pass to get to the corresponding point. For example, when you drive at real 116 km/h (120 km/h as displaying speed), the speedometer arrow should be at point #4 and arrow's motor should pass specified number of steps at steps point #4.

So you need to calculate middle step points (between 0 and 7153) accordingly to your speed points.
For example, point #4 again:

116.0 km/h of 250 km/h (point #5) means 116/250 = 0.464. Multiply it to maximum amount of steps (7153) and you will get amount of steps to get to point #4. 3319 steps in this case.

So try to calculate points #2 and #3 by yourself using the same method. BTW be aware that it works only if your dial is marked linearly (with equal speed steps).

Hey, maybe you answer this question snce i dont quite get the logic behind that.

I've got an 1 135 with 1M look cluster dial. 

Effective real speed:
0.0 / 7.8 / 47.1 / 116.0 / 268.0

Display speed:
0.0 / 10.0 / 50.0 / 120.0 / 300.0

Motor Steps:
0 / 248 / 1242 / 2982 / 6960

After youre logic, i have to do following math:

116.0 / 300 = 0,38 | 0,38 * 6960 = 2644.8

0 /  180.9 / 1092.7 / 2644.8 / 6960
That would be the right motor steps for the cluster to work properly for every  block of the cluster. Is that right ? Or am I doing something wrong, I know theres a lot of information in this forum but I didnt get wat i wanted...

Just got a general question about the oil temperature mod.

Is there a cheat sheet where all the available emgines are listed where the mod works?

Since I’ve tried it on our 330d 231PS and it didn’t work. Only the consumption works. But on a 330I it worked.

Does it work for 335d or are all the Diesel Motors excluded?

works perfectly on my diesel e70 30d 235hp 2009

Ive got another question, maybe someone can help:

I have a e9x cluster with 330 Dial mark.
Till 120 km/h the gauge is linear, after that its not.

How can i calculate the steps i need between 120 and 330 so the speed will fit between drive speed and shown speed ?

I've calculated 17,775 steps per Km/h till 120 kmH

For 120km/h to 330km/h its 14,006 steps per KMH.

Is there a way to calculate that ?

What's the total number of steps for the whole dial?

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.

This tool can activate cruise control for retrofiting without cruise function odometers for e60 or e90 kombi

Worked, thank you Very much, now I know how to calculate it

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?
