General Disclaimer to Start Off
You shouldn't blow your car up doing this. Don't make map changes unless you know what you are doing. If you do, don't blame me. You typed the number in. You flashed it to the car. That being said, I've never heard of anybody doing damage by logging data. Bottom line, as a blanket statement, I'm not responsible for your car. Just putting it out there.
This is the first entry in a string of threads that I plan to write. I have been road tuning my own car now for over a year now (with help from others), have learned a good bit along the way, and wish to pass some useful knowledge on to others. I can’t supply a “conclusive tuning guide” through forum posts – nor am I qualified to do so.
I’d recommend picking up the following books to get a head start if you want:
• Designing and Tuning High-Performance Fuel Injection Systems by Greg Banish. Short book. Great initial overview.
• Turbo: Real-World High-Performance Turbocharger Systems by Jay K. Miller. This book goes in depth on JUST turbochargers. Given that most other books are general tuning books, this is a nice supplement. Lots of pictures and a surprisingly interesting read
• Engine Management: Advanced Tuning by Greg Banish. Short read, but a bit more in depth than the earlier Banish book. Good read though.
• Forced Induction Performance Tuning A Practical Guide to Supercharging and Turbocharging by A. Graham Bell. This book is not for the timid. It’s long, somewhat boring, and old. That said, I learned most of the fine details that I know from this book. If you are serious about it, this will take you back to the “classics” of tuning – an important aspect commonly overlooked on forums I feel. You’ll learn a ton though if you can bite the bullet and make it through.
• Maximum Boost: Designing, Testing, and Installing Turbocharger Systems by Corky Bell. I haven't read this one yet, so I can't offer an opinion on it. It did receive good ratings on amazon, which is what I based my book choice off of.
• Performance Fuel Injection Systems: How to Design, Build, Modify, and Tune EFI and ECU Systems. by Matt Cramer & Jerry Hoffmann. I just finished this book. It was a good read, but focuses more on using standalone ECU's or retrofitting an older carb'd car with an EFI system. You'll go down into the fine details - most of which is magically done for us guys using the stock ECU. Good book, but I wouldn't put it as a priority.
There are some good links that Matt has posted below. They contain some great information. I am only posting books above due to the ease of understanding the material, the assurance that they are written by a credible person, and the logical order the material is presented. That does not mean that an internet thread is bad, by any means. I just wanted to use this opportunity to give credit to the authors above, as well as provide a nice concrete starting point.
However, I am writing these entries assuming that you have not read those books. I know not everybody has enough time to read all of the above. My posts will focus on newer 32-bit ECUs with open source ECU definitions/parameters. I can offer some suggestions for the older ones on request. I will also assume you have some version of excel that isn’t from the Stone Age.
