If NYO make it corectly, so play with him. For example: write 0 km, note the change in hex make by NYO, after write 1, 2, .... 100, 101 km, and feel the diferences. So you can find quickly algo.

RE: Nissan Dash Millage Manually
If this was a dump from a dash, the math won't always work because the mileage value is in a constant state of flux when driving and may not be saved as a perfect string before the car is turned off.

Looking at your string, the last word doesn't seem right, in a perfect string it should be 5d 94. think

Mileage calculators are not always dead accurate either because of the multiplication factors, and they don't always calculate to the exact desired Km in these complex algos. Not uncommon to enter multiple desired mileages within a certain range and get the same answer.

You would need a larger sampling of good dumps (not from a calculator) to give you a better idea of where/if you are right or wrong.

Good luck.

If someone took the time to help you, the least you can do is take a few seconds and press two buttons!
