EEPROM reprogramming and test digital cluster

I'm from a small cluster repair shop in Australia, we are now wishing to take up more modern digital cluster, both with programming odometers and testing clusters,

Firstly we are looking for a suitable programming tool for odometers, The brands we commonly see are:
- Audi
- BMW
- Ford
- Holden
- Honda
- Hyundai
- Isuzu
- Lexus
- Mazda
- BMW
- Mercedes Benz
- Mitsubishi
- Nissan
- Porsche
- Subaru
- Suzuki
- Toyota
- Volkswagen

Looking around I have seen mention of beeprog, Xprog m and UPA programmer, I am hoping to cover direct eeprom reprogramming via a windows based tool as opposed to a field tool so that we can store and archive the dumps.

Next would be a way to test digital clusters, so far we mainly accept the instrument cluster directly which has limited our ability to test devices where the speed, rpm, temp etc are provided by other devices over a can bus,
After inquiring with http://www.obdexpress.co.uk/, the customer service advice me X-prog m and UPA programmer for best eeprom reprogramming tools, these two programming tools are best-selling with good quality and good reputation, and work with the above car models.

As for the suitable programming tools for odometers, digiprog3 or digimaster 3  from Yanhua Company is the best choice, they have better quality then other clones. it can do most german cars with obd (not bmw). and it can read dumps and save to pc.

then you can use NYO V4.0 to change mileage of lots of cars.
