well man thanx i tried it and my ecu is reseted and the performance of the car is better. thanx a lot man
if yor trying to reset any adaptions on the ECU make sure you use all yor rev range so the ECU learns to fuel properly, it often helps to do this to motors mainly cos when cars are new people tend to bed the engine in and keep revs reasonably low, so this is the first thing the ECU learns, thats why the sometimes feel a bit unwilling when you do decide to plant it 
So is this ECU reseting worthing doing as a "matter of course" even on the likes of my car (110bhp non PD)

to reset your ECU, you have to do a little more than just disconnect the battery and plug it in again.
Disconnect the battery and leave disconnected for about 30 mins.
connect the battery back up and go put the key in the ignition.
Open all the doors, boot and bonnet and turn the key to get all the lights on. (This i am told alligns the throttle body)
Close all doors, bonnet and boot and get in the car.
Start the engine and turn everything electrical on, opening the windows full and then back up again. (This teaches the ECU what the maximum amount of electrical output maybe required from it.)
Turn everything off apart from the car and go for a spin
I personnaly wouldnt bother reseting my ECU as a matter of course. I only ever donr this when my fault light came on and it was my MAF sensor. I reset the ECU to see if it was a problem with MAF or a faulty sensor.

Ok, out of curiosity then:
If you've had an ECU remap and you go through a reset process like this, do you effectively lose those settings if you do the above, or is a remap permanently stored in a way that what the ECU has learned (like what the max electrical draw might be, as in the windows example above) is reset but the other settings (the increased bhp and torque!) remain?
Coz I'm thinking. My Leon has been remapped, but if I do the above, wont it learn and adapt to my driving style from scratch, rather than the guy who owned it for the first 18months of its life?
