ECU Reset Question?
How frequently can I reset the ECU as it does make quite a difference? Can I do it as often as I want :? :?:
Also what is the best way to reset the ECU :? I heard you can do it by pressing the brake and disconnecting one of the battery terminals or by plugging and unplugging the green and black switches under the dash then driving it slow and then hard once they're unplugged again :?: Just had to add I've done it twice using the green/black plug method :? |

Daz - well you can reset the ECU as often as you like but doing it too often would not be a good idea. The reason I say this is that once you have reset the ECU's parameters everything is wiped. The ECU now relearns knock correction amongst many other things

You can reset the ecu as often as you like.
Nelson wrote, about doing it after the car being filled with poor quality fuel, after any mods being done etc. On my 02 and new 03 could not see the black plugs on either, so had to do the neg terminal off trick, (confirmed by garage) followed by the drive at 2500 revs for 6 secs and seemed to work. All i can add is if its worked for you then that would be the sensible way to go in future. buzz |

Daz - as per Buzzs comments - its also a good idea to reset the ECU after carrying out a Modification
![]() Once a week IMHO is a bit to regular. Maybe once every few months etc or sooner if you suspect a bad batch of fuel. My previous comments still apply though - if you need to reset the ECU that often, because the car is down on power then I would suggest that your car has a problem and resets are not gonna help you find it, unfortunately ![]() ![]() |

resets work well on the pre 01 setup
but not on the 01-newer the ECU's differ and dont 'forget' much you really need the correct program / data logger/ select monitor to clear the car properly...especially if you get a bad code. The new ECU will not 'just forget" and the code / check engine light will come back on.... (trust me, been there done that... still dealing with it! ) ![]() on the older GC body.. reset by disconnecting neg terminal (10-20mins should do) reconnect start the car but do not touch the gas pedal let it idle for a bit and there ya go....

Thanx Guys
There were no error codes it flashed frequently and kept regular but just seems like it feels a bit fresher with a reset! Probably my imagination
![]() Will do it once a month or so then! Thanks again for the information nice to know some guys are clued up ![]() |
