Facelift and 2nd facelift change milage

I promised some people id translate the guide i made for the Dutch Micra club to English. So here it is.

Its possible to change the milage of the digital clusters. Its easy to do and the tools are cheap.
Do note i did this with a KM cluster instead of a Miles one.

Requirements:
Programmer with SOIC-8 test lead. (Im using a EZP2013 clone) With the software installed.
A cluster (obviously)
T8 screwdriver
Plastic fork
Pliers

Step 1:
Remove the front by pressing in the 4 clips at the top and 3 at the bottom.

Step 2:
Use the plastic fork to gently pull of the needles

Step 3:
Remove the 4 T8 screws

Step 4:
Push in the 4 clips at the top and then the 4 at the bottom and remove the backside.

Step 5:
Bend the 4 metal lips straight and pull off the pcb

Step 6:
On the front of the PCB is a 8 pin chip.
This contains the milage
The pin thats closest to the big square chip is pin 1. The pink wire in the test lead should be on pin 1.
Connect the programmer to the computer and connect the testlead.

Step 7
Open the programmer software and select the following chip:
Type: 93 EEPROM
Manufacturer: ST
Name: M93S46

Check if it tells device connected at the bottom and press read.

Step 8:
I DO NOT KNOW IF THIS IS THE SAME FOR MILES. SOMEBODY PLEASE TRY IT AND LET ME KNOW.
Change the first line to the needed milage and press write.
This milage needs to be in inverted HEX and needs to be repeated 8 times so that the first line is full with the 4 characters.

The formula im using for Kilometers is as following:
Milage/16 and then convert this answer to hex.
Then convert the hex value to inverted hex.

For example:
80000/16=5000
5000 in hex = 1388
1388 in inverted hex = ec77
So the first line for a milage of 80000KM will be EC 77 EC 77 EC 77 EC 77 EC 77 EC 77 EC 77 EC 77

IF YOU HAVE A 2019 PROGRAMMER YOU NEED TO SWITCH THE CHARACTER PAIRS.
To use the example above: With a 2019 programmer it will be 77 EC 77 EC 77 EC ect...

Here is a sample table for the milage in kilometers with the inverted hex values:

KilometersInverted Hex Value
100000E7 95
110000E5 24
120000E2 B3
130000E0 42
140000DD D1
150000DB 60
160000D8 EF
170000D6 7E
180000D4 0D
190000D1 9C
200000CF 2B
210000CC BA
220000CA 49
230000C7 D8
240000C5 67
250000C2 F6

And a helpfull table for hex to inverted hex.

Dont forget to press write after changing it.

Step 9
Press read and check if you get the same as you previously filled in.

Step 10:
Disconnect the programmer and put the cluster back together.
Bent back the metal clips (Else the LCD wont work)
Dont forget the rubber domes.
Small tip: Wait with the front and the needles and test it first.
