Found this among some old notes, thought it might be useful.

How to reset your ECU:

Disconnect battery for 45 minutes.
Reconnect battery and turn ignition to MAR for 90 seconds.
Turn ignition off and leave for 90 seconds.
Start engine without pressing throttle, let car idle for 15 minutes. Don't touch anything else!
Turn off engine and leave for 10 minutes.
Your ECU is now reset, go for a long drive covering all driving styles and cycles.
