quote: Daimo, thats utter bollocks mate. As engine life increases, a natural increase of dangerous exhaust gases happens. To combat this with the help of the lambda sensors, the ECU recalibrates fueling and airflow. Add an induction kit (although drilling your airbox is much better and a whole lot cheaper) and there will be a considerably larger amount of colder denser air entering the inlet plenum. Now to stop the wrong mixture of fuel/air, the ECU must now increase fuelling. The standard ECU is controlled by fixed variables with a maximum fuel and air mixture right down to a minimum. Whether resetting the ECU after adding various small parts to your engine has yet to be proved. An aftermarket chip is great for adjusting fuel and air mixtures by much greater variables, and also removing rev limits, upping turbo boost etc etc. Dave | |

reseting the ecu does nothing i'v done ot loads of times to my car after i fitted my KnN and zorst its does nothing and the car doest even splutter.. | |

It didnt do anything to mine, no spluttering it just idled perfectly instantly and made no difference and this was overnight aswell. | |

ok well look at it this way, if re-setting the ecu recalibrates air/fuel mixture when u put mods on ur engine, then why do people buy unichips to re-map their engine? | |

when i reset mine it didnt splutter or anything. how can it adjust to new induction kit etc when hardly any air is being sucked in when idling? | |

corsas only have 0-1volt lambdas so the car doent know HOW rich only that it is rich it is on w.o.t not like the not current switching ones so it can't afectivley "calabrate its self) | |

An induction kit is known to increase air flow due to pulling colder air denser air in, the ECU controls the fuel air mixture, so resetting the ECU should in theory recalibrate it to an increase air flow so then should get rid of problems such as flat spots and give you a little bit more pull. | |

why reset the ecu it will achieve nothing ?? i work at F1 in bolton, ecu and fuel injection is what we do and my corsa runs on gas, an air filter will not change the fuel trim!(which is what you will reset) its all in your head if you think it did anything? | |

Well I found that it improved performance. the ECU as standard is setup for the standard car, it should over time adjust to become calibrated to the current setup of the car, disconnecting the battery means the ECU has to reset and when it recalibrates itself it should be calibrated to a new part in the engine. | |

Oh, i lie, i have to keep resetting the electric windows, date/time display, thats it :P | |

The standard ecu is setup for the standard engine. It wont reset or adjust in any way to suit an induction kit :lol: | |

After you've re-connected the battery, when you start the engine it is 'supposedly' meant to cough n splutter while the ECU recalibrates itself, but mine has never ever done that, just idles as normal almost immediately. And that's after having the battery d/c overnight. | |

I believe reseting the ECU allows it learn again (due to the induction kit) how much air/fuel to mix into the engine etc.. :look: | |

After reading about reseting the ECU on the electrics part of FAQ's, I did it for the first time yesterday, after fitting an induction kit months ago. Boy the power feels more responsive! If you've just fitted an exhuast or induction kit go and reset the ECU now!! |
