A Dynojet is supposed to account for which ever gear ratio you make a run in - but it does not do it in the real world.
What kind of O2 sensor does the crossfire have? A nertz or wideband?
We've done quite a bit of testing on a Dynojet here in town (mostly Miatas), and we are in the process of building an engine dyno (Stuska) - but that little project is sort of on the back burner.

Hi Henry,
The dyno I was using is a
MAHA LPS3000 which I am told is highly regarded throughout Europe and is approved by Audi and Porsche, although I have been told some people don't like them because they tend not to give 'impressive' HP figures. I think the runs were in 4th gear from memory, but I am not reading too much into the numbers until we manage to get a full redline run.
