Anyone know what it takes to be able to do it yourself? What sort of tech or device is necessary to do this on a 99-02 or 03-06 cluster? I'm thinking about buying an Escalade cluster but want to be able to program my actual mileage into it before installing it. I am familiar with all the dash rebuilders that can do it as a service, but I'm wondering about being able to do it on my own. Most rebuilders want $80+ to program mileage and are hard pushing a full rebuild for $250+. Not really interested in that option. Thanks in advance.

It’s quite the involved process from what I understand. I believe @DougAMiller has some insight on this topic right?!

I, too, would be interested in this process.
There's some recent chatter about the subject here...

takes a eeprom programmer and software, you may end up spending far too much time and money trying to figure out how to do it when you could have just had a speedo shop do it. unless you are going to be doing things like this for a living it's not worth the time to me anyway, usually you can find people on craigslist that do it for side money

@Austinite has an nnbs but he just did his himself.

I describe how mileage is stored in the EEPROM and what it takes to reprogram it in this thread. I was actually making the change to turn on the trans temp gauge, but I mapped out much of the contents of the memory which included the mileage.

Ah yes now I remember the adventure on the trans temp gauge! Lol. There’s a ton of great info in your thread!

Just pay the $80 and save yourself the headache and expense of an eeprom programmer and software unless you just want the experience of doing it yourself. Unless you’re planning on doing it on a lot of clusters it’s not worth it IMO.

Not wanting to de-solder and add an IC and capacitor, I found this on ebay:

I'll let you all know how well it works.

Interesting. AFAIK you can’t program the mileage through the OBD port. I’ll be following to see if it works.

Well, that was a complete waste of time.
Did you at least get a refund?

Oh yeah. I made it a point to buy from within the US, but I still ended up communicating with someone from China or thereabouts.
Out of curiosity, what happened when you tried to program it? And what did they say?
Looks like they had to update their listing due to an error. Must have said it actually worked.

Odometer adjustment eh....hmmmm. Seems super illegal to me.
Nah - It probably has a disclaimer saying don't use it to cheat or lie.
Any time you sell a vehicle you have to make an odometer disclosure.
