2006 Buick Lucerne Cluster help

[Beigei]

Sorry to bother but im pretty sure i googled the brains out of this problem. I have tried all the calculators and software's going through one by one with the mileage that is on the cluster trying to find if any matched the dump from my cluster and could not find any. the cluster i bought has over 100000 more than my car so im trying to match the mileage but i cannot for the life of me find out what to do. so i am here. so far my dump is 342497km or 212818mi and the string is 1a 21 i have change the 21 to 79 and it went to 216xxxmiles so i know im in the right place but where to go from there. I dont want to just make it lower which i know i could probably do, i want it to match the cars mileage. any help would be greatly appreciated

p.s. the chip is at25020AN

I just flashed it anyway but it read out 123745mi. Just a FYI. Thank you very much for your time. I tried and tried to no avail so the towel was thrown. Thanks again

Buy a decent cheap obd tool and save yourself all the hassle., any cheapy will work like obdstar x300m xtool pro2 even a smelecom ds3 clone anything takes 30 seconds no hassle
