EFI Means Easier Starting EFI Delivers Reliable Power at Altitude While carbureted engines struggle in extremes of heat and cold, EFI automatically compensates to set the ideal timing curve and fuel mixture. For every 305 metres above sea level, carb engines lose significant power and need to rejet at 1828 metres. EFI automatically adjusts to changing altitudes.
