well you disconect the negative pole on your battery for I think it was 15 to 30 sec. But you do that when ever you change any electrical stuff or sensors, anything that will flash you a code, the purpose of disconecting the battery is basically to clear your trouble codes and reset your computer.
Well if you do all that will happen is the stored memory will be erased. THe car somewhat adjustr itself to your driving habits. I don't think it will help anything, unless you want to change your driving habits, which for a 16 year old with a Camaro it aint changing soon. So no you dont have to though if its anykind of electrical mod you shoud disconnect your negative post while your working on it.
After you do any mods you are "supposed" to disconnect the power (which BTW you are supposed to do when ya work on yer engine <----- read the chiltons). Leave it disconnected for 10 to 15 minutes. This resets the computer and erases the memories. When you go to restart your car it will most likely come to life and promptly die. Restart again and it should idle fine and might surge. Go for a drive on the highway for about 15 miles, the car WILL surge for about 25 to 50 miles. Mine hasn't died but it will surge from 400rpm to 1100 and stabilize at 600. Anyways the whole point is so the computer learns the new mod and adjusts for it. I have done it quite afew times with no problems with the exception of whats above.

Red91's right. The computer will re-adjust anyway after a mod, but when you reset the computer, it has a clear memory. It doesn't have to un-learn anything; it learns everything from scratch.
If I do something major, I'll drive away for a half hour on the highway, and then come back- total driving time = 1 hour.

Do not place too much "faith" on the Block Learn. Basically, it stores values from various cell that seem to work the best and will use those. This is strictly for "closed loop" operation and just gets the correct cell quicker.
It does not "compensate" or "readjusts" for mods per se. If the mod requires additional fuel, it can only give the additional fuel within the constraints of the BLM/INT at CLOSED LOOP.
@ WOT or open loop (like when first started, prolonged idle or long deceleration down a grade), the BLM does not function and you rely SOLELY on the tables within the eprom. If the tables are not correct, you car will not perform properly.
Bottom line, Block Learn does not compensate when the real solution is a new eprom. And what compensating it does, it only does at part throttle and while in closed loop operation.
