Title: MOT emmisions question
Post by: Andy B on 01 June 2010, 23:40:53

I took her Smart for MOT today ..... it passed  :y. While it was hooked up to the Boston Garage Equipment for the emmisions readings, part of the display shows rpm. How does it know what revs it's doing when the only electrical connection is to the battery terminals? At one time there used to be a connection via an HT lead, but this kit just has the pipe up the exhaust & the battery .... how does it know?  :-/  :-/  :-/  :-/

I wonder if it detects pressure pulses in the exhaust? :-/

The tester's mate had to alter a controller to 3 ..... which I assume was refering to number of cylinders  :-/  :-/
