Status: offline 		Just a reminder. If you have a shut-down there are three great ways to diagnose the reason.

1. In the info menu the "LAST OFF-COND" variable will tell you why. For example, low RPM, high temp, fail-safe etc. This parameter is non-volatile and will be available until the engine is run again.

2. With V4.0g and later ECU you can view the last 4 seconds of the flight before it shut-down. This data is updated every 0.2 seconds. This allows you to see the trend leading up to the shut-down. This mode is entered by pressing the "+" key of the GSU and powering up the ECU. You then can scroll through the data using the "+ or -" key and scroll forward and backward through time using the "info or min/max key". This parameter is non-volatile and will be available until the engine is run again.

3. As long as you do not power-down the system, you can down view the entire flight using the RS-232 adapter and a PC.

If the off condition is "POWER-FAIL" then the data is not valid. This occurs if the ECU or receiver battery was disconnected or was intermittent or if the receiver power goes lower than 3 volts. In this case, the data in the system would be for the previous run.

This information is very useful to diagnose why the engine shut down. Either Matt or myself will be available to help you interpret this data.
