hold changes gears ealier and usually starts in 2nd gear?
power obviously does the opposite, lets the motor rev more freely and leaves the change until you back off the throttle a bit
dno where the hell you got it hold the brake?
maybe get that checked out?
This thread made check mine out tonight and what I found was that the power light and mode are on whatever position the switch is in!!!
Something has stuffed up somewhere, maybe from the swim a few weeks back?
