Hi! Not sure about your last question

Hi!
In your car or truck, what ever you drive, you have on your dashboard,norma lly in front of your steering wheel, a instrument cluster were you can see your RPM, OIL pressure, Water temp and your Mileage.

Hi Jos!
Those are what I have now for samples, as for a manual, I wish there was one. When you referred to sampling 1m, 2m, 3m etc I'm assuming your talking about 1 mile, 2miles, 3miles etc. I guess if I started with 1 and put a mile on and read it every mile, I probably could. Don't know what the meaning of the bytes are other then the answer (miles). You asked why 6, I don't know. Some other clusters use 2 bytes others use 5. I've tried...

Hi everyone! This is my first time posting a question here.
I am working on automotive instrument clusters.
I need help figuring out the formula they use in the examples below. I can read the codes they use in the Eprom and see the "answer" on the digital display on the instrument cluster. I just can't figure out the formula.
ANY HELP WOULD BE GREATLY APPRECIATED!

5A 03 E2 03 47 00 = 25906 Miles
