I have a 175 ETEC. I have been told by my dealer that the ETEC fuel transducer will not read until calibrated. (Currently always reads 0.0 l/hr) Trouble is the main dash guage will not allow me to make any adjustments when trying to enter the exact amount of fuel consumed to calibrate. Does anyone know exactly how to set this up correctly? (I have read the manual but I'm hoping I'm doing something incorrectly. Quick taps on the 'M' button scroll the menu and holding it in selects the desired function)
