Description
This is an improved Honda NT400L MKII Bros NC25 KW0, KW0b ECU Replacement.
What is better compared to the original unit:
– increased protection against over-voltage (such as a defective voltage regulator/rectifier, bad battery).
– higher resistance against a defective ignition coil and reverse battery connection .
– acceleration correction: when the RPM increases the ignition delay changes (in proportion) resulting in a smoother acceleration.
– digital technique: therefor the unit is more accurate and less sensitive to temperature changes.
– optimized ignition curve/map to improve engine performance resulting in more power.
– spark power control: the unit will change the output to the ignition coil when the battery voltage changes in order to keep the spark power the same.
– start mode: during engine start there’s a start delay and the unit will give more current to the ignition coil for a faster start.
This ECU is used in the models below.
