Loaded 20648 did have 20163 after a lot of apprehension and high pulse rate watching the load bar creep along it reached the 100% and load complete
Then when I came to start it nothing just a click so with the heart rate now hit maximum and the thoughts ( sh#t what have I done) did a check back and only thing not done was plug back the fuse for the lights put the fuse back in and Pressed the starter and it fired into life
Reset the TPS all went well no faults shown then looked at the fuel and it was showing zero but no fuel light I have a full tank. I took the bike out for a test run and the fuel gauge reset itself
. The engine feels to rev more freely so need to try it for the next few weeks but the first impression is its better so no longer a TunECU virgin.
