Programming of E-Prom and processor

The simple use of an E-Prom programming and a processor programming  

By this kind of speedometer adjustment the speedometer unit must be remove. The speedometer must be split. The adjustment will be make via a memory chip, the E-Prom or via soldering points in the back of the cluster. So it is not necassary to split the dash complete.
Here a listing, that kinds E-Prom are obstructed that into vehicles:
