I think he means RESET the ECU, not reflash.
Unplug your battery, let the engine cool down, plug it back in and start the engine.

The ECU learns adaptively to your mods, your driving, and the conditions. So everytime you put another mod onto your car, your ECU takes a while to learn your mod well enough to adjust itself for maximum potential. By resetting your ECU, you basically erase all the learned memory and force your ECU to relearn all your mods much quicker than it would take to just fly with it.

To reset your ECU,
Turn your car off.
Disconnect the battery terminal.
Depress on the brake pedal several times to move the juices out.
Let your car sit for 20 minutes like this.
Reconnect your battery.
Start your engine and let it idle for around 25 minutes.
Then take it out for a drive going through your entire powerband in 1st and 2nd gear.
Continue driving in varying conditions and in a week or so you ECU should be set.

You should also note that you should fill up with your favorite gas and drive around for 40 or so miles before doing this to help your ECU learn your fuel preference and that for a week or so, your mileage will drop significantly.

A reflash is basically a reprogramming of your stock ECU for the purposes of aftermarket engine management. A reflash is similar to a piggyback or standalone engine management system such as a UTEC, however the reflash maintains a 'set and forget' stock feel.

25 minutes is way to long
disconect the battery for about 4-7 minutes. Depress brake pedal if you wish a few times.
reconect the battery and turn the car on... it may stall instantly. but just try again.
do not give it any gas just let it idle for about 3-4 minutes
turn the car off
start it up again and go for a drive using various driving styles from aggressive to calm.

Drive around for a bit and your ECU will continue to learn your mods. Hope this helps.

Bringin' back a dead thread!!! Caplin, how'd you make out with resetting your ECU? Has everything returned to normal?

I'm asking because I'm getting ready to install a CAI and custom cat-back.

Thanks,
Bill
