easy as 1..2..3 man,, disconnect your neg battery for at least 5 minute or so.. turn key on to drain out any store current in the ecu capacitor...put back neg connector .. thats its..

Haven't heard that one before, but doesn't mean that it won't work. Here's something a little quicker, disconnect neg battery terminal for at least 60 seconds, then depress brake pedal for a minimum 10 seconds, reconnect neg terminal and that's it.
We all know that there is always a constant current feed to the brake lights at all times irregardless if ignition is on or not. By depressing brake pedal you're doing the same thing - draining any transient current remaining in cars electrical system (including ECU).
