Hi All

I retrofitted the cluster from mono to color in my W212.
I used a Instrument Cluster from diesel donor to petrol. I don't know how to change the tachometer so that the rpm is for petrol, I looked everywhere but I couldn't find such information.

The second problem is in the on-board computer, it shows correctly in After Start and After Reset, but after turning off the car the information disappears. Previously, on mono, After Start kept the memory for about 4 hours, and After Reset permanently.

I have flashed it before, here is the current firmware

ECU: C_204
Diagnostic ID: 29 09

Diagversion: IC218_212_207_204Mid_AeJ12

How to improve it?
I looked everywhere but I couldn't find such information.

I will be grateful for your help.
