Does the ECU only program itself for the first few hundred miles? I would think it would constantly be averaging the previous driving experiance and recalculating itself, isn't that the point of an ECU that programs itself? It can adapt and change as the engine changes needs.mensajero said:When installing remember to reprogram your ECU. Just disconnect the positive battery terminal. Leave it off for a few minutes and then reinstall it.
Oh not that I was scared to pull the battery, did it a month ago to install my amatuer Radio, just curious how the technology worked, couldn't see it just using the first hundred miles to decide how the engine would run for the rest of it's life unless reset.peterpogi2005 said:i think the ecu remembers the last 40 starts or so. if you make a change to the engine, it can run like a dog coz it can't adapt to it until it's averaged out the last 40 starts. pulling the battery resets the ecu to it's default settings and it starts averaging-out again from the first start with the engine change/mod. therefore, it will adapt the change/mod much faster.
so much for the theory.. just try it in practice!! a mechanic will pull the battery anyway if he/she's doing anything in the engine & it'll drive ok after it's reconnected.
