Description

This is an improved Yamaha YFM350ERT 1YW-21 ECU Replacement.
What’s 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 replacement kit is used in the models below.
