first buy a wideband O2 sensor that is compatible with
the tuning software you intend to use. these range from $99 (VW) to $399 (Bosch) of course this will depend on whicn sensor your software will accept. |

second, data log your car in the gear closest to 1:1.
for wrx's 4th gear & sti's 5th gear. after data logging, examine the data. post for replies and comments. |

I know of no complete tuning guide as yet. I have considered trying to do one, but I don't have enough experience with some aspects of tuning yet. Reading what Ride5000 has posted is a very good idea.
What I can tell you is that you need to be methodical. Make incremental changes in whatever part of the tune you are working on, then go log. Logging is of utmost importance. I keep a three ring binder of my logs with notes on each log. I highlight portions of the log that I want to change for the next version of the tune. I also annotate air temp, date and what version of the tune was used. |

I agree jax, but I like to get my boost tuned and my fuel and timing in the ballpark before I go to the dyno then I play with it a little to get my final tune. I usually don't touch my boost tune on the dyno. I'll only change my fuel and timing. Dyno time is expensive.

This one's for an open source standalone called megasquirt, but the ideas are all the same- go to megamanual dot com and see the tuning section. (I don't have 8 posts or I'd link it)

Get the book " How to tune and Modify Engine Management Systems" by Jeff Hartman for starters.

Have you read this book? If so, what is your opinion on it? Is there anything it does not cover very well?
Thanks, Tim |

No one book covers it all. These three are the ones I would recommend most. I've read all three cover to cover at least twice. |

I spent alot of time in Japan learning, this book is one I stumbled across and I have recommended it to anyone who doesnt understand the Whats and Whys of ecu tuning.
At a quick glance it seemed like a good starting point. Jay-R |
