Hello,

I want to correct The mileage on 2005 Gmc Yukon, Is their a way to do this, some say remove eeprom chip, and some say threw obd2 plug, regardless how can I do this? Thanks

I think best way is to take dash out and read the memory should be 25020 or 95020 and then correct it.

Thanks for the reply andy, Now is their a way to program the eeprom without removing it? wlould a eeprom clip work?

I have few different programmers if you want something cheap and ok to do most eeproms check for easypro on ebay. Around $100

Ok andy I ordered off ebay a hot air soldiering unit, a wellem programmer and a easypro programmer, Im just waiting on them to be shipped out to me sometime this comming up week, after I remove the eeprom wich is U15 on the cluster board, I put it into the programmer and connect it to my pc, then i use ponyprog to read the eeprom, then I use tachosoft to correct the right miles, then save them onto the eeprom????

you got it right, but be very careful with wellem programmer sometimes you have to adjust the speed otherwise you can get incomplete reading/programming. Try to use both programmers to read the original dump and save it. If you new to this buy some memories that you going to work on and write corrected dump to new memory leaving the original intact in case something goes wrong you'll have a backup. Prepare yourself for damaging a few dashboards so go to local junk yard get some dashes and practice on them.
