Checking ECU Voltage

The Webon Alpha ECU needs minimum 9 volts from the ignition switched supply during enging cranking.  Checked this with a voltmeter while cranking and all was fine - just over 10.5 volts.  Thought the starter motor would have to work harder with the spark plugs in so tried again, this time with the starter motor working against the engine compression.  No problem here either - still around 10.5 volts.
