what is the acceptable air/fuel ratio range that our integras can have? the reason im asking is because im going to dyno tune and want to know if im running lean or rich. i have a 2000 LS with i/h/c/e and cams. i searched but only found that the leanest i should be is about 13.5:1

You have a lot more reading to do but at partial throttle you should be looking for around 14.7:1. That is the stoichiometric value for air to fuel ratio. When at WOT I have heard to shoot for about 12.5 - 13:1. You do not want to go lean though!
the website Hondata has a fairly detailed approach to tuning at WOT- however like most will tell you, every engine is slightly different so fine tuning may vary.

I've never tuned a car yet, but have been doing some researching on the topic and it is better to compromise a little performance for a reliability factor, a.k.a keeping the mixture rich.
I've been reading a book called "How to Tune and Modify Engine Management Systems". Its not too bad for information on how to tune. You can find it on Amazon.com.
The book gives a lot of info on the different types of sensors and how they work, and also the obvious, how to tune, although the info is in bits and pieces throughout the book..
I personally thought the Hondata method to tuning is very instructional, methodical way of tuning a N/A engine, if it is accurate.
Good Luck with the tune
