That's what I'm trying to tell.Having said that, I'm quite amaze at my FC at 160ph.. constant for 120km, FC recorded is 8.8L/100km. :top:Last weekend I think I was again caught by the speed cam on PLUS. Shooting down from a bridge some where near Sungai Buloh, 3rd lane, North bound.. looks like to enjoy the drive, I just need to budget RM500 a year for speeding tickets.. and I can greet every speed cam with a grin.. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite8" alt=":D" title="Big Grin    :D" loading="lazy" data-shortname=":D" />I am suspecting its just a calculation error with the OBC because our FC counter does give us a quite accurate estimate. Try out with a full tank, reset the odo and see how many liter used up for X km when you next refill. The same value should be displayed on the OBC.I'm not surprise to see the FC counter moves up when car idling. Its mathematics. If you have just reset the FC counter, it start very high if your car in not moving. Its base on average speed where in this case, your average speed is 0! <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite9" alt=":eek:" title="Eek!    :eek:" loading="lazy" data-shortname=":eek:" />A short drive after the FC counter reset will bring the average FC down but if you go stationary again not long after the drive, the FC counter will go up fast. Say you drove for 2 mins at 100kph and manage to bring the FC to 10L/100km, then you stop the car and idle the engine for 2 min, your average speed should now be 50kph. Idle for 4 min and your should get avg speed of 25kph.. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite9" alt=":eek:" title="Eek!    :eek:" loading="lazy" data-shortname=":eek:" /> of course, your FC counter will move in tandem with the slowing down of the average speed when the car is idling. Average speed down, FC up!When u notice the above, how long have you been driven the car after the FC counter reset?</blockquote>
