How do I modify a stock ECM to run with performance parts installed, say a bigger cam or a turbo for example.

I mean DIY very low price tricks, not buying exotic chips or reflashing proms, things we all can do at home, like installing a variable resistor in place of the IAT sensor to richen the mixture or tampering with the distribuitor holdown to advance the timing, etc, etc.

How do I turn the CEL off (besides removing the bulb) after I removed the catalyst, etc.

please tell us some secrets, and smog cops don't worry, we will never run a modifyed car on the streets.
It depends on what vehicle you are talking about but I am a firm believer in using EFI Live. You can do just about anything you want to with this program and not have to install any "chips". Yeah, it costs a little but if you plan on keeping the car and have the time to fiddle with it, EFI Live is the program of choice. Once you learn it, you'll love it.
