Okay, gonna try it again and give you an feedback. Would be pleased if you could look though on it again

Thank you very much!

I used the M3 Buffer without modifications, now I can set the Speedo to 330 with INPA/Tool32 but I still have an difference of Max. 30kmh. If I enter 50 the Speedo shows like 40. If I enter 150 I get like 120/130 kmh on the Speedo. With low and high speed it's very near on the right speed but at middle speeds the difference is to high

Hmm, maybe there is a difference in the dial sectors. Using my guide, try using the 280kmh sectors in the new 330kmh nettodat

Hi, I have a little different problem, but very simillar to blax123. I have e92 335i US and I swaped us speedometer to ECE version (ONLY GAUGE FACES) problem is that orginal scale was 260kmh now it’s 280kmh. I must use digital speedometer to know how fast I drive

Can someone please help me out how to code 280kmh calibration?

Here is my readout adress 0x3100 from tool32:

CODIERDATENBLOCK                = 33 Bytes

Ok so call me silly but I am thinking i wanna instal the aem CD-7 niw that they habe the obd-2 cable. Just prop it right in front of the factory display plug in and set up my screens.

Should i start a new thread when i buy one. I suppose lol

[Notorious99]

My nettodat modul kombi.
I do not see the addres 0x3100,0x3101,0x3102,0x3103,0x3104,0x3105 for coding scale speedometer, oil temp, RPM gauges.
Is that normal, I do not understand

I now have some space. That's normal. You create custom nettodat. I'll show you.

I've done 260 km\h to 280 km/h conversion!!

I want to thank Sensible_ for help from previous post to understand how to modify NETTODAT file.

Everything works fine but cruise control marker works in 260km/h scale. Could you please give me the values from adress 0x3101 (335i clusters v max 280 km/h)?

Thanks!

Congrats,

Care to share your nettodat file on the forum? I think it will be useful for some others

Paste your 0x3101 coding block here

I calculated X, Y, S Ranges for my clusters:

My clusters 260km/h US:

CODIERDATENBLOCK                = 33 Bytes
    0000 : EE 3D 03 00 00 3A 00 C6   01 DD 04 AB 09 00 00 50
    0010 : 00 E2 01 07 05 0E 0A 00    00 90 00 62 03 07 09 0E
    0020 : 12

From code above we have:

X: 0, 58, 454, 1245, 2475
Y: 0, 80, 482, 1287, 2574
S: 0, 144, 866, 2311, 4622

I don't know why my values from Y Range wasn't equal 10 km/h (100), 50km/h (500) 130km/h (1300) 260km/h(2600) - NEVERMIND

Next step I figured out that I need values like this (+/-):

X: 0, 78, 471, 1160, 2691
Y: 0, 100, 500, 1200, 2800
S: 0, 165, 825, 1980, 4622

So it was:

CODIERDATENBLOCK = 33 Bytes
0000 : EE 3D 03 00 00 4E 00 D7   ‪01 88 04 ‬83‬ 0A 00 00 64
0010 : 00 F4 01 B0 04 F0 0A 00   00 A5 00 39 03 BC 07 0E
0020 : 12

I added this to NETTODAT:

B 00310000,0010,EE,3D,03,00,00,4E,00,D7,01,88,04,83,0A,00,00,64
B 00310010,0010,00,F4,01,B0,04,F0,0A,00,00,A5,00,39,03,BC,07,0E
B 00310020,0001,12

Now everything works fine, but I have error code 3392 - Time to short to correlation to engine-coolant cooling:

- Instrument cluster disconnected from Terminal 30 during stacionary phase (battery change)
- Collateral fault stemming from a defective engine temperature sensor
- Collateral fault from incorrect time signal from instrument cluster

I removed this code and will testing it tomorrow

CRUISE CONTROL MARKER:

Values from tool32 0x3101:

CODIERDATENBLOCK                = 23 Bytes
    0000 : 5F 50 00 00 80 00 01 01   82 01 08 02 07 01 9D 10  _P..?...  ?.....?.
    0010 : 32 20 C8 2F F8 3F BF                               2 E/o??
  _TEL_ANTWORT                    = 30 Bytes
    0000 : 9A F1 60 62 31 01 5F 50   00 00 80 00 01 01 82 01  ?n`b1._P  ..?...?.
    0010 : 08 02 07 01 9D 10 32 20   C8 2F F8 3F BF 31        ....?.2   E/o??1

[Levanime]

good job,

second scale is for "corrected" speed

[Notorious99]

Nice job, I have to change a speedometer e60 535d from 260km / h to 330km / h. I have already changed to display the oil temperature instead of the engine consumption. When did you see the errors?

I have the same problem, someone to find the solution?

[AoD]

Could someone please give me readout of 335i (max 280km/h) with tool32 at address 0x3101 ?

[morepower]

Just to make it clear for everyone,

In 0x3100 (Speedometer scaling):

What you have called X,Y,S to the different 5 values groups:
S is motor steps to show Y speed in the needle.
X is road speed that will display Y if speed (de)correction is enabled.

Table:
X speed corrected =bytes 3-12
Y speed shown by S =bytes 13-22
S needle motor steps =bytes 23-32

--------------------------------------------------------

In 0x3104 (VFW or Redline marker scaling):

You have 5 rpm setpoints related to 5 motor-steps.

Table:
Rpm = bytes 3-12
Steps = bytes 13-22

-> DDE or DME has a table to request this RPM.
You can always mess with the steps to get lower/higher
redline with the same ECU request.

i lack readings from 0x3101 from E90 M3 and E60 M5, if anyone can share them to compare data i would be thankfull!

[Notorious99]

Hi,
Thank you for your help, but I have a 535d e60 and I can not change the scale of my speedometer from 260km / h to 330km / h. I copy the nettodata buffer into my meter and it does not work.

Any idea if these apply to F-xx cars? Am in a similar scenario and need to change scale from 260 to 330

[Notorious99]

no idea for F series, sorry

Conversion 260=>330 work in my E60.
Tools32 does not give the right value on the 330km / h scale it is necessary to make the test while driving.
Tools32 uses Min and Max values ​​to display test values

Hello
I have the same problem with the buffers. I dont have buffer 0x3100 in my netodata. I have a european car.
Can somebody help me out?

Thanks

This is an outdated method now. Download Perfekt Toolbox. It's very easy.

Thanks a lot for telling me about that software. I have 1 problem. I testet it succesfully with 300 km/h but have problems with original m3 330 km/h cluster. The 300 km/h cluster adds at every point + 20 km/h but the 330 km/h cluster does this until 120 km/h and adds then +30. I have tried many options but it doesent work. I think i need to code some netodata from the m3 cluster?

I hope you can help me with that
