Looks very interesting!
I would like to see an independant test to see just how accurate it is.
As a one off power figure it may be ok, but I dont see how u could set up a fuel inj. system with it without monitoring the fuel/air ratio. Surely if
you just keep adjusting it to get a faster acc. time u will end up with a melted piston

You could always build one of these as well , i have a circuit diagram for a fuel air meter using a standard Lambda sensor and displaying on an led
bar graph , im sure it wouldnt be to difficult to add in the results from this as well.

Just been searching and found this page
www.drivewerks.com/tech/street_dyno.htm
It has a downloadable version of basic software and details about how to record directly to a laptop.I just need to find an old cheap laptop.
I havent yet found my fuel air meter diagram but did find a couple of others by searching for diy fuel air ratio meter.
