When on my recent rip to Sydney/back I wanted to use the trip/fuel functions of my Scangauge II. I noticed that when I filled up that the part where you tell it how many litres you put in was adjusting painfully slowly and showing something like 300-litres. I gave up it was sooo slooow... Then when I selected the instantaneous litres/100klm display it was giving very odd looking results. Way high. Like showing 34 l/100klm when simply cruising in 6th.
So seems something has gotten screwed up somehow. I wondered if it might have been when it was disconnected earlier in the year during reapirs.
Anyone seen this before and got an idea how to correct this? Other functions seem OK.
