Hi again,

I've decided to wait on the lowering kit and just do clear corners and a CAI. I got some advice from a friend about reprogramming the ECU to give me better economy and smoother engine response if I was to put in a cold air.

I just wanted to check in with some of you guys to see if this is the right thing to do:

After you get a performance upgrade (i.e. exhaust, intake etc.) make sure to reprogram the computer:

* Turn on the car and warm it up (make sure that it is at normal idle).

* Turn off the car and pull out your ECU fuse located in the fuse box under the bonnet.

* Keep fuse out for at least 5 to 10 minutes.

* Plug fuse back in and close bonnet.

* Start your car making sure not to touch the accelerator.

* Let the car idle (at its normal idle) for about 5 minutes.

* Shut off the car and restart it. Take it for a test drive and you should notice the difference.

After doing these steps he told me that it should work. He said the ECU is originally programmed to mix optimal amounts of air and petrol for a factory spec car (no modifications). By taking out the fuse you kill all power to your computer, therefore resetting the 'program' that gives you the right mixture. By not touching the accelertor as you fire it back up, the ECU will reprogram itself to give you the best MPG possible based on your current set-up.

Is this all legit? Also, where is the fuse box that they refer to as being under the bonnet? Is that just the area under the steering wheel that says fuses?

Thanks.
