No, it looks interesting but I wouldn't want to be standing in front of
a motor at full throttle when it lets go!  I have spent a few hours
playing with a mixture analyser and a long pipe up the exhaust which
worked reasonably well if you had a mate to check whilst you were
driving, it was a little slow on changes in mixture though!

Another method that works is welding a lambda sensor into the downpipe
and using the readings from that, demon tweeks do a led display that
you can use with it for muchos dosh or you can just decipher the
voltage readings (between 0 and 1v normally). There is a circuit around
that lets you mount a stack of ten LEDs into your dash and will give a
really good indication of mixture when you are driving!
