How to modify a stock ECM

let's forget about emission or legal stuff, let's say we are talking off road only here.

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.
