Thank you so so much for the help! It really worked.
(don't forget to save the changes before rewriting the EEPROM😅)

Now I only have to figure out a way to cut the difusor behind the dashboard...

glad to see its working. I've ordered the LED's and chips from digikey, hopefully it'll arrive soon and try this mod by myself.

is it hard to do the "soldering" part?

Just take your time :)
I used a small soldering tip and small tweezers. Was a bit fiddly but worked on the first try. Just make sure, you dont have any shorts
thanks for the tip :), as for the "tachoscheibe" I don't know that in english. Have you sourced it?
I'm sure the "tachoscheibe" need to be custom made as the standard one did not have the pattern on the RPM gauge to show the LED's.

while letting the car warm up, I stumbled apon some strange behaviour:
The LEDs turn off in the order 1 to 5, but the circled LED in the top right corner stays on... Is that supposed to happen?

I have M3 cluster on my car, but its the original m3 one, it act the same like yours. When the engine is cold like I've parked the car for a night then in the morning I turned the car up the LED's is fully turn on like the picture below, but when the engine is on fully working temperature the LED's would go down to 7000 RPM. So I think yours is completely normal.




here is my LED setup on the MS43.

Maybe u can read out an eeprom from your cluster and upload it here so we can take out a speedo and tacho curve and adjust normal cluster to corectly rev to 9k rpm?

While operating the regular cluster with the LEDs we notice that they are only properly placed inside the m3 cluster since the segmentation of the rpm is slightly different.

so to do it like 99 percent correctly you would need to solder some wires and then move the leds to the proper position.

one question though, where did you bought your cluster overlay?

Ideal u need to use m3 overlay. In the video he say it. But he didnt have calibration from m3 cluster. So in my opinion we need to copy kva_tachometer from oryginal cluster to normal cluster and m3 overlay u can buy everywhere.
