Ok l ll look that .. At .55 volt difference look AFr change .... l use Five Ops injector thanks

hello l use G4+fury ecu, the problem l have is dead time cycle on battery volt, have no charging systeme used. !!! Dragbike with 2 injector by intake runner. 1- l made a run at 13 volts bike run good on AFR 13.2 2- made another run and battery volt drop to 12.23 AFR look rich 11.5 a setup the fuel again to 13.2 AFR going to another run battery volt going to 12.45 volt AFR is good 13.2 3- next run exemple: battery volt going 13.v again AFR going to be very lean again..16.1 at top end ... it`s look the injector dead time table dont work good. with Variance of volt. thank you Stephan
