Fuel strip to float conversion complete guide.

[botus]

I did write the float mounted on the pump of a GS (20 litre tank) will give silly readings compared to a strip

when they decided you could use a float on the small tank bikes they added a bracket (I thought went by the fuel filler) and you attach the float to that - where it sits very differently

I forget if it will get less awful when it sees max min

yeah, i have the filler mounted potentiometer from a 2010 bike. Will recheck my settings tomorrow. Maybe I got a bit overzealous changing things..If that fails, I may order the Spanish strip and swap pins/programming back to stock.

OK, just spent some time reconfiguring the coding, trying all sorts of settings to no avail, only to discover my sidestand was down ... gah!! Went back through methodically and reactivated FLS strip for both xx and yy. The gauge seems to be behaving normally now. I even unbolted the fuel fill, and played with different float positions and the gauge responds pretty much as expected. Also recoded the tank back to 20 liters from default 19. Good idea or bad? Will update with real world results.

I think it might get its bearings after seeing what full up and full down looks like - I don't think you can do it off the bike as the movement of the float inside the tank is restricted - but when the bottom never changes as that's the lowest it can mechanically reach, I think it may see that as the new empty

mine doesn't have the ZFE high so I have the short lived probeemer box of trick to fake the float signals at the ZFE strip inputs - and so can't say for sure

I tested the float movement, through the fuel pump hole, max and min, with the level sensor installed, and it makes it full stop, top and bottom, without being restricted by anything in the tank. The behavior before, with xx and yy set to "lebel", it would indicate empty with barely any downward float movement. That serms to be corrected with the new coding.

not sure what you changed ?

there is no lebel - just Hebel = Lever - AKA float sensor
I can imagine code it off and on again might create a refresh of what its doing

when its on the new bracket where does the float point ??? backwards or ?

i meant "hebel". It points forward, but towards the left half, or wing, of the tank. It's installed correctly with no interference from internal tank structures or components.
It seems counterintuitive, but I changed the xx and yy parameters, under "fuel level sensor" back to the default, "folienge" from "hebel" (see my screenshot above). Gauge started working normally. The new coding still includes changing FLS 08 to "potentiometer" and inductive fuel sensor to "deactivate". Again, it seems to be working normally now, but a long test ride will confirm.

Hi everyone

I post my first here just to say thanks to denz0 for his guides to switch to float sender. I am riding a 2008 r1200rt and was stuck with the dead strip for a long time. Not until I found this thread then I find hopes someday my bike can get rid of the yellow triangle and show some fuel level. It takes me one weekend to finish the job. When I saw the fuel error & yellow triangle gone, fuel level on I am all ecstatic. For the rt riders of high zfe (mine was a police model), just follow denz0's instructions and a pdf you'll find in #115. And go ahead invest in motoscan & OBDlink LX, I can now clear the codes myself, no need to see the technician (he said I did good despite of losing a customer).

£1 and you could have had the lights off all those years - make up the mess of resistors below - pop the plug off the top left of the tank and pop those tails in the multiplug loom

light off forever and gauge shows it full up

Resistors!!!! Earlier this year I spent 2 or 3 weekends trying to fool zfe with a combination of various resistances, the one in the photo included (I also replaced the 33 ohm with 50 ohm because that's waht I found on my failed strip. All failed and the mechanics said my zfe shut down the sensor monitoring because someone failed the calibration before. So switching to float is the only option left.

I would also like to thank denz0 and everyone else who contributed to this thread.
I followed the instructions here and converted my R1200GSA-10 to float three years ago and since then the fuel gauge has worked perfectly!
The first owner I bought the bike from (a friend of mine) had major problems with his fuel strip, three replacements in total.
He wanted to have the dealer convert to float (late 2010 GS(A) have float sensors so he thought it should work) but they said this was an impossible conversion.
How wrong they were!
I also recommend MotoScan to anyone who owns a BMW motorcycle. The most affordable diagnostic tool I have ever bought and I have bought many over the years

did you fit it the correct way around? I have one set up to match the above picture it works 100% reliably - of course the connector you push the tails into needs to be wired and coded as per a heated strip
