Higher Altitude
Ok, so I just moved to Denver was wondering if I should do anything to the car to adjust for the higher altitude? Someone told me to pull the main fuse from the ECU to reset it, but I am not sure.

I don't think you need to do anything. In the old days of carburetors, I think you had to switch out the jets ... but with fuel injection, I don't think you need to do anything. I think your MAP sensor (or something like it) makes the adjustments automatically. If it was me, I would probably take my car to "Courtesy Acura" in Littleton for my next oil change and ask them if anything needs to be done.

You don't need to do anything. There is a barometric sensor in the ECU and the MAP reads manifold absolute pressure. So all needed data is known on how to compensate for the greater altitude.

Correct me if I'm wrong... but I believe that the ECU also does some relearning for driving conditions to fine tune what the maps contain.

You can speed the process by disconnecting the negative lead from the battery for 20 minutes. The ECU resets then and "learns" faster.
