Story is I have a friend that has an EVO IX, and is looking into getting bigger injectors. So he asked me some questions about tuning with larger injectors. Now I understand the basics, but some of the questions he was asking me had me scratching my head. So my question to you guys is, do you know of an article or a book I can pick up that will really go into depth on fuel injectors. Such as in depth discussions about PWM, duty cycle, latency and the affect the battery voltage has on it, as well as fuel trim correction factors. And what is necessary to tune an engine on larger injectors. Any direction you guy can point me would be excellent.

I would like to be able to help my friend, but I would also have need of the info in the not to distant future.

Just so your post doesn't go to waste. I know that some of the more expensive multimeters can actually tell you the duty cycle of injectors by calculating how much of the time that the injectors are open.
