ECU Reflash License Tohatsu MFS9.9 / MFS15 / MFS20
1 ECU reflash license for newer Tohatsu MFS9.9 EFI, MFS15 or MFS20
HP output will be 25
Did you know the MFS9.9 is the same basic angine as the MFS15 and MFS20? This allows us to tune them all to a well tuned 20 that will make 25HP. The only difference from the factory is a small intake restrictor and tuning. You must run modified tuning to remove the restrictor on 9.9 and 15 models.
The fuel and ignition curve is optimized for 89 octane (95 EU for outside North America) or better fuel, Torque limiters are raised to a safe level. This allows Outboard EFI to easily get to the max HP and slightly beyond.
