GPS doesn't account for altitude changes. If you live in a flat area it's not bad.Originally Posted by NeilSmith
The computer doesn't detect spark plug changes at all, not even unhooked. That just puts the computer back in to "learn" mode all over again and resets all of the sensors. If there are any changes that computer should make due to the plug change then it would eventually optimize itself, but it will take some time... you just force it to do it sooner by disconnecting the battery.it just sounds funny to me that if the computer knew what it was doing then it would automatically detect that you changed the plugs and you wouldnt have to unhook the battery to reset the system. im old fashioned , i guess.
