Arrow Acronym Help

I guees this would fall under troubleshooting as it would help me to know what everyone is talking about and how to sound like I know what I'm talking about. What are the acronyms? PCM, A/F, etc, etc. I get so lost but it sounds cool. Just wish I knew what you guys are talking about. Help please!

PCM - Power Control Module (Your Computer)
A/F - Air/Fuel Mixture, usually refers to a gauge or a lean or rich condition.

List some more and I can help you out but I cant think of any off the top of my head

What is Rich? Lean Condition? Is that good or bad?

ok heres a good list for ya

pcm - powertrain control module (engine's computer)
bcm - body control module(controls everything inside the car like lights, radio, speedo, tack, etc.)

a/f - air fuel ratio - this is a way to measure the ratio of air to fuel in the cylinders... the middle ground is 14.7/1 meaing their are 14.7 parts of air per every 1 part of gas in the cylinders... running lean means you are running more then 14.7/1 ratio in your cylinders... meaning you don't have enough fuel... running rich means you are running lower then 14.7/1 ratio... which means you have more gas in the cylinders.. now both lean and rich are not good things unless you completely tune the car

tunning the car - to tune the car you use a dyno which emasures you hp of the car and also measures your a/f ratio while running.. from this information they gather they can tell if your car is running to rich or to lean and try to fix it as well as play around with it a little to see if running it richer or leaner in certian sections gains more hp

CAI - cold air intake

Yes. You'll always get the most power out of your car if your running "Stoich" (14.7 air fuel mix, on regular gas). If your running rich your ok but you just have too much gas than air so your car isnt getting the power it could. If your running lean, thats dangerous cuz your car could not get enough fuel and could seize or blow up.

if you run to rich tho you can flood the cylinders and wash the walls meaning you take away all the oil which could also cause seizing
