Went for ride today. Was full when I went out and bars dropped as normal. Filled up and the bars usually go all the way to top after a few miles. However, gauge is stuck on the number of bars it had when I filled up. Disconnected battery but made no difference. Anyone got any ideas?
By way of update - new sender arrived. Another Triumph rip-off (£80). Anyway, fitted it and still not working. Plugged into Tune ECU and did a reset and now all fine.
What type of fuel did you use? I've found that filling my ST with E10 causes problems with the gauge under reading. If I use super unleaded (E5), it reads correctly
Could this be due to the two fuels having different specific gravities? After all the sender unit is basically a mechanical device, isn’t it? I ask because I’m still in analogue mode from my old Ducati and are not entirely familiar with the electrickery on these modern machines yet.
