Hi again doc, some more info and a video.
Voltage tested at engine cold is 4.04 volts ( 2000 ohms ) 1500 rpm
and hot engine measures 0.909 volts (300 ohms ) 1050 rpm
Interestingly i could not get the engine to idle below 1050 rpm? ( low rpm issue ).
Seems perfect for the a/d converter in the cpu in the ecm ( geeks only ).http://cb1100forum.com/forum/images/smilies/cool.gif
Please be careful not to damage the little terminals inside the eot sensor, this is a bit of an advanced test which requires knowledge of electronics and connectors!
Really good request of the vin numbers, it may relate to a particular batch that had something different done.
The issue is that japan does not have any faulty bikes to test and that makes it hard for them to come up with an answer,
so if we can give them some numbers they may find something that relates to this batch of bikes.
New youtube video on today's test with the relationship between the eot sensor and change of rpm

as usual; cheers Max
