Connected up a Navman fuel computer to a Navman 5505i tracker a few weeks ago, and filled up after my first long run. The Dorset trip we did in June was 94 miles or thereabouts for me, and the fuel computer said I had used 117l. filled up at the weekend, and she only took 92l.
Went into calibration mode, entered the 92l for fillup and thought all would be well. Then went out, and all weekend, the computer was showing a consumption figure, but always negative
. Whilst I am happy to produce petrol from my engine
moneyis more likely to grow on trees, so what have I done wrong when calibrating?
Guess will have to reset it next time, refill again and start over. But, can't see that I did anything wrong, unless I should not have told the computer I filled the tank prior to calibrating it?
