Fuel strips. Need to know resistance strip values in ohms

Hmmm you would have to think in all the strips replaces under warranty if it was as simple as a software change they would have done it.

Not all bikes have the air temp sensor, only the ones with the computer. Apart from that on a day of 20c the fuel would only be 20c before the engine runs after that it's temp wouldn't be predictable.

Just musings - thinking aloud.

Thinking again (always dangerous). It's unlikely that ambient temperatures make much difference. The relative cooling from the fuel compared to air is a pretty profound difference so the small change of ambient is likely to be insignificant. After all, it's only a level indicator, not an accurate metering system.

My knackered fuel strip looked fine. The copper tracks have not signs of over heating so I suspect the problem is in that glass hard epoxy pack. What's the betting that had they used something flexible like polyurethane (allowing some limited flexing) it would be fine.

Maybe there's a clue in how they fail. I've had two strips fail but they were different. One was a total failure in that it suddenly stopped reading anything, the fuel warning came up on the dash and the yellow flashing icon went off. The other strip however carried on working but once the fuel level got to a certain point, 2 bars, it wouldn't drop any further. It would work fine between those ranges but stopped at the 2 bars. Maybe there's two different types of fault occuring, one a partial and another total failure. In both cases I tried using the GS911 to calibrate the strips. The strip with the total failure just came up with an error but the partial failure would calibrate as far as the GS911 was concerned. It still only went down to two bars though.

There are two failures. The total failure is the one the pizo trick can sometimes fix. I seem to recal it being the heater circuit that was open circuit. The other is inaccuracy one way or the other. All 3 of mjne were accurate enough at empty but all over the place above that. Not the worst failure and I didn't trust it but when it said empty it pretty much was.

Mine seemed ok at all levels until it stopped working. It was zapped a couple of times but then stopped for good. At low fuel I don't remember any warning other than the remaining miles counted down to zero but the bike was still going. I never got to deliberately run it dry to test the real limit before the strip failed.

I also wonder if they over heat, maybe under that epoxy. Someone who does high miles and always fills the tank will have more petrol sloshing about to keep the strip cool. Part filling the tank has less calling effect, the strip runs hotter and fails sooner.

But saying all that, mine looked fine, though it has totally failed.
