Fitted a Techlusion fuel booster thing to my 1150GS today. This necessitated disconnecting the O2 sensor. The bike goes like the clappers now which is great BUT the fuel gauge is now reading all over the place. It’s like it’s lost the electronic damping that stops it reacting to sloshing fuel. One minute it’s showing full, then half empty. If you stop riding, switch off and then on again it will show the correct tank level. I know it all works on resistance and I was wondering if anybody else had had this issue after disconnecting their O2 sensor?
