I have read about people Resetting their ECU's by unplugging the battery. I have put intake and HKS exhaust on my car, and neevr reset the battery, would it pay off? If so , how long do i let the batter ysit unplugged for? Another thing...I have a "Ebay intake", (but it has a K&N filter), and i had the throttle body too far bak, so i moved it directly behind the filter...since i changed the MAF location, would it be wise to reset my ECU?
Thanks

yes it will be nice to reset it. just talk of the + wire for 15 min. then put it back on.

Just unplug positive, I dont have to touch the neg. cable?

DO NOT unplug the Positive lead of the battery. Unplug the Negative lead for 5 minutes. That's it, very simple. Some OBDII scanners will also do a PCM reset.

What is the big deal with the positive or negative terminal of the the battary. It doesn't matter you are still breaking the connection no matter what.

i would think that the positive cable would be more likely to spark when removing or reattaching, at least without discharging the battery first. the positive cable does the job just as well without risking damage to the electronics.

Nate is right, which is why you always disconnect the negative wire first. If you leave it on and disconnect the positive and it happens to make contact with anything, zap!
