Support and Troubleshooting

MyECU is not an invincible piece of hardware. Electrical problems with the bike are just as likely to damage MyECU as they are the WMECU. The major difference is with the serviceability of MyECU. With the MyECU schematics available and the use of readily available parts ( except the microprocessor ), the original intention was that the rider can now troubleshoot and repair their own controller. However I understand that most riders will still not be able or desire to do this. Below is an outline of how I intend to support MyECU. Prices are in Australian dollars.

Within the first twelve months I will repair or replace MyECU for the cost of postage and parts.

After the first twelve months I will repair or replace MyECU for the cost of postage and parts and labour. This is not the pay through the nose labour, but a reasonable $30/hr, shouldn't be more than two hours type of labour.

For those who have gone for the full or short form kit I will repair MyECU for the cost of postage and parts and labour.

Installation step one

With the ignition key off, pin 3 of the MyECU connector should show 12 volts. This is connected to the battery via the ECU power relay coil. Pin 5 is the "keyed" power and should be sitting near 0 volts at this time. The ECU power input, pin 16 should also be zero.
When the key is turned on, 12 volts is fed into pin 5. This turns on the transistor which in turn pulls pin 3 down towards zero volts, energising the ECU power relay. 12V should now be supplied via pin 16.

Initialization of the microprocessor turns on the transistor for approx. 2 seconds. This can be seen by a 5V signal on pin 21 of the chip and pin 4 of the connector being pull towards zero for the 2 seconds.
