    Yeah cheers mate, followed ur instructions on monday, easy bloody peasy, with resetting me ECU by unplugging the battery as well, the car is running great at the mo, using half of much petrol, even sounds nicer, little rumble, even with the standard panel filter in.

    Cheers matey!!

    I aslo used this "how to" to do mine - very easy to follow 10/10 Just have to decide which panel filter to go for - looking like PVD or Ramair at the Mo.
    Just one question though - What effect does resetting the ECU have?

    Libranet....

    As l have put a new exhaust system on, and de-restricted the air box, the mixture/fuelin was probably out, by re settin the ECU, and lettin it idle for bout 5-10mins, it does a scan of the car when it is 1st started up after you plug the battery back on and resets all the mixture/fuelin etc, thus takin into account the performance bits you have fitted.
    Mine feels alot smoother and not drinkin as much.

    Hope this helps mate.

    Do you have the Cat 1 Vauxhall alarm on your GSi, if so its got the battery back up. I read somewhere in the manual about this and how to disconnect it. Hope that helps a bit

    Can you just pull out the ECU fuse? If so, where is it? (I haven't looked if it's very obvious)

    haha, OMG spot the old wives tale.........disconnecting the battery to rest the ECU, sounds like something Powerflow would say!!!

    IT DOESNT WORK, ALL TEST RE: THIS THEORY HAVE PROVED INCONCLUSIVE!

    The theory is, that if you reset your ecu by discon. the battery, then drive like a loon for a few miles, that the ECU adapts to the driving style...

    In practice it doesnt work, the ECU has a battery back -up preventing anything like this happening. THE ONLY WAY TO ADJUST THE AIR/FUEL RATIO IS TO HAVE IT ROLLING ROADED.

    If the ECU was reset this easy, then any warning lights you had would disapear, (i.e. airbag, abs, tc warning light) but by discon. the battery, these lights wont reset, therefore meaning that if by disconnecting the battery the ECu cant even reset a few warning lights, its highly unlikely its going to reset all its settings re ignition, timing, exhaust gases, fueling, air temp/mixture!!!!!!

    Just thought i'd let you know!
