Haven't used it, but I DO have some comments.  I visited the guy's
website and read through the info there.  In addition to his software
and pickup, there's a bunch of other stuff you need to use it.  An
alternative exists that is FREE, requires a lot less anciliary hardware
(you need a stop-watch and/or a microcassete recorder or equivalent,
plus you need spreadsheet software that will handle or convert from
Microsoft Excel), is an SAE-approved testing method, and will result in
very accurate numbers, providing the numbers you input are accurate.  A
fellow named Jon Glommen put together an Excel spreadsheet using this
testing procedure, and it is available at the TurboBricks website.  The
spreadsheet's page is located at:
http://www.geocities.com/MotorCity/4242/dyno.htm

I was able to get Quatro Pro to translate the Excel file, dunno about
other spreadsheet packages like Lotus 1-2-3, but I suspect it shouldn't
be too big of a problem.

After doing my test runs and inputting the data, the numbers I came up
with were right about what I thought they should be.  Nice thing about
the spreadsheet is it gives you hp and torque figures in 2500 rpm
increments, PLUS because it's a spreadsheet, you can customize it for
your own applications, PLUS you can have your spreadsheet software
generate graphs of your results.
