    Starter button no go

    Hi everyone,
    The currently published configuration file ( ‘1 Kawasaki Ultra 250 260 - FP Std - SC Std - Oct 95 USA 98 AU EU.e35’ ) for the Kawasaki Ultra 250 PWC can fail to power up under some conditions :
    If the PWC is stopped for longer than 4minutes 50 seconds with the Lanyard Cord still attached to the Kill Switch, the ECU will turn off a secondary relay which turns off the dash and disables the Start Button. Once this happens the ski will appear to be powered down, but is actually still powered. Without power to the Start button there is no way to wake up the ski.
    This occurs only if the Lanyard is still connected to the ski. As the Lanyard currently controls an Ignition Switch function, the M400 Power Hold function on Aux3 will not turn off the ECU while the Ignition Switch is on.
    Once this has happened the only way to re-enable the ECU is to either unplug the ECU itself from the adapter loom and re-connect, or unplug the KPE Device (8 Pin DTM) from the adapter loom and re-connect.
    To avoid this with the existing configuration it is essential to remove the lanyard whenever the ski is not being used. If the lanyard is removed within 4 minutes and 30 seconds (while the dash is still showing information) the ECU will power down normally, and restart when the Plastic ignition key is re-inserted.
    This can also be remedied with the existing configuration by executing an ECU Reset (using the ‘R’ key on the PC) before disconnecting. This will power the ECU down and the plastic ignition key will need to be re-inserted to power up.
    We have amended the published configuration file (now named ‘2 Kawasaki Ultra 250 260 - FP Std - SC Std - Oct 95 USA 98 AU EU.e35’) and suggest you make the following change to any existing configurations you have installed on this PWC:
    In ECU manager, change the Auxiliary 2, Dig In 1, and Sw In 2 setups:
    1. Auxiliary Out 2 Function to 118: Power Hold.
    Auxiliary Out 2 Parameters: On Time 20 Seconds.
    Polarity 0.
    Output Mode 0.
    2. Dig In 1 to Function 29: Monitor.
    3. Sw In 2 (AT2) to Function 4: Dual RPM Limit.
    Sw In 2 (AT2) Parameters: Logic Polarity 0.
    Sw In 2 (AT2) Parameters: Low RPM Limit 100.
    Sw In 2 (AT2) Parameters: RPM Rise Rate 0.
    Sw In 2 (AT2) Parameters: Ignition Retard 30.

    This does the following:
    1. The Stop Switch/ Lanyard Cord will now kill the engine using Dual RPM limit.
    2. The M400 will turn off the relays after 15 seconds, even if the lanyard cord is still attached. If the M400 is connected to a PC, the power stays on until the PC is disconnected. Then it powers down after 15 seconds.
    If at any time the ECU does not power down, you can unplug the KPE device for a few seconds and the ECU will lose power. It is not required to unplug the ECU, just unplug the KPE.
    Also remember that any time you are making map changes and the PC asks you for an ECU Reset, the power to the ECU will also stop. You just need to press in the plastic key again to start the power. Or you can hold the plastic key IN before you do the ECU Reset, this keeps the power on always during the ECU Reset.
    If you need any further info just drop me a PM
    Cheers

    Isn't there a one minute delay sometimes when the ECU restarts itself when the lanyard is knocked out? If so, is there a fix to this or is it something that you'll have to deal with when you have the Motec ECU? Very interested in getting one.

    Hi
    Here is what will happen now with the new set up.
    If mid race you pull the lanyard accidentaly and reconnect it within 15 seconds you can push the starter and it will work instantly.
    If you leave it for longer than 15 seconds then you will need to repush the key to wake up the ECU again.
    I can change any of these times if someone wants to send me their config.

    Cheers
