The M130 Yamaha FX SHO plug-in ECU closely mimics the standard OEM operation. With the following operational differences when the kit is installed:
- The M130 Marine ECU engine control functionality is the same as the standard factory ECU; all normal operations on the PWC are possible.
- The M130 Marine ECU controls the Yamaha Instrument Cluster and mimics the original factory dash operation. The ECU controls the dash via the KTC (K-Line to CAN) data adaptor.The KTC receives CAN messages from the ECU, and then transmits K-Line messages to the instrument cluster. CAN messaging from the M130 to the KTC is fixed.
- To prevent engine damage, the following dash alarms and revolution limits are provided:
Cooling
When a PWC Plug-In ECU is fitted, the engine power will increase. The standard Yamaha cooling system might not be sufficient in its supply of water to the engine and over-heating can occur. It is important to check that the cooling system is working adequately.
The maximum engine temperature should be 88 ºC (190 ºF). If your engine overheats, the dash alarm will come on and the revolutions will be limited to 4500 rpm.
Note: There are three separate engine temperature monitors on the Yamaha. The engine temperature switch, mounted on the front right side of the engine block, is used to control the dashboard alerts and RPM limiter. The alarm temperature of this switch is 88 ºC and is not adjustable. The engine temperature sensor, mounted on the rear right side of the block, will reduce the Drive-by-Wire throttle when engine temperature exceeds 105 ºC. A further precaution is controlled by the Race Time system. When the engine uses full throttle for extended periods, the engine tuner can adjust Compensation tables to reduce engine temperature. The fuel mixture can be enriched using the Race Time Fuel Mixture Aim Compensation table and the ignition timing can be retarded using the Race Time Ignition Timing Compensation table.
Power Control Functions
The standard Yamaha WaveRunner uses an Immobiliser and Start button to power up the craft. If the Immobiliser is unlocked, press the Start button on the left handlebar will start and run the engine.
The installation of the PWC Plug-In ECU bypasses the Immobiliser, rendering the PWC permanently unlocked.
Otherwise it follows the same strategy with the following provisions:
- If the engine is not started or is stopped for a period longer than 60 seconds, the M130 Marine ECU turns off its own power. Power is not re-applied until the Start button is pressed again for an engine start.
When making tuning adjustments to the M130 Marine ECU using M1 Tune software, an ECU reset may be required. In this case, power is removed from the ECU and the Ethernet connection to the PC software is halted.
To re-connect, press the Start button for a short time until the engine has cranked, or for a longer time if you want the engine running. The Ethernet connection should re-establish and you may continue with tuning adjustments.
Using the Power-up Adaptor Plug if the ECU needs to be powered for longer than 60 seconds without the engine running, for example when sending new firmware, the ECU power should be controlled externally. For this purpose, a separate 2 pin plug is fitted to the Adaptor Loom. Connect the two pins in this plug together via a switch to turn on the ECU power relay.
When finished, the switch should be removed to return to normal power control operation so that the ECU has control of the power relay. Failure to do so will cause the battery to go flat.
Security
The standard Yamaha Immobiliser system uses a Key Fob transmitter to Lock/Unlock the PWC. If the immobiliser is locked, the Start button will not crank the engine, thus preventing operation. When the PWC Plug-In ECU is installed, an Immobiliser Bypass device renders the craft permanently unlocked.
It is important to secure the craft when not in use, for example, by removing the Immobiliser Bypass.
RiDE (Reverse with Intuitive Deceleration Electronics) 2016+ VXR, FX and GP1800 Models
In these models, a reverse lever on the left side handlebar is configured similarly to the normal throttle lever.
Yamaha’s original behaviour for these systems is that the reverse lever operates both the reversing bucket and the throttle, unlike competitor Sea-Doo.
Many users prefer the Sea-Doo method where the reverse lever operates the bucket only, with the normal throttle lever always controlling the throttle.
The M1 solution allows either control method. The Reverse Lever Throttle Aim table will take control of the throttle if its value is greater than zero when the reverse lever is used.
Yamaha OE Control Method
Enter values in the table to conservatively open the throttle when the reverse lever is applied.
Example:
Alternate Control Method (Similar to Sea-Doo)
Enter zero values in all table cells so that the reverse lever does not control the throttle when applied. In this method, the reverse lever operates the bucket and the normal throttle lever operates the throttle.
Example:
