Gas gauge calibration unit

It took about 40 days to get these 5 boards for a total cost of $5.75. That is why I ordered so many. It is very common for me to purchase more than I need if it is not available locally.
So far, my fuel gauge is working to specs.

I am still waiting to hear how much Mr. Kit's assembly is going to cost.
I would also like proof that it works

Stop trying to turn this into an argument over ego, which is exactly what you sound like. This is about different approaches to a problem, and in your case, I see no way to allow for differences in gauge unit and sender unit differences from car to car.
