Ronnie the way you discribe how to reset the ecu, is different, but not as much messing about as the other guy's way? doe's your's do the same thing? and whats a mashed lambda???
Dazzer cheers for all the advice aswell....
:slayer:
The other way is the official way - mine is cheating - both yeild the same result.
Think of the ecu as if it were a pc:
A pc has ROM (read only memory) - or a control chip (incidentally some people replace or remap this chip the alter the ecu's instruction set).
It also has RAM (random access memory - which will only store it's contents if it has power going to it.
When you disconnect the ecu from the battery power, you are in effect clearing the ram to the car's computer - so it forgets the driver's settings if you will.
The car then loads up the default mapping for the engine and goes into learn mode to adapt to any differences, and saves this information in the RAM.
The re-learning process takes about 100-300 miles after a reset - but this process takes much longer for the engine to adapt to changes if a reset has not been performed, as the car simply assumes that everything is normal.
To answer your other question, a lambda sensor lives on the engine end of your exhaust system and monitors co2 levels so that the car can control things like emmisions by altering the fuelling.
Only problem is that if you add an induction kit (and you do it properly) you are forcing cold(er) air into the engine - which burns faster than warm/hot air - and as a result requires more fuel to be sent to the engine.
If you are forcing the car to have more fuel than it thinks it needs (or at least trying to), then basically one of two things happens -
*The car doesn't adapt, doesn't give you the extra fuel, and the engine ends up running lean for the airflow it's receiving (and as a result will stress a lot of the engine componants out, and make the car run hotter).
*The car partially adapts, but you end up frying certain sensors (this is particularly noticeable if these components are coming to the end of their lifespan anyway - which I'm guessing is what happened to mine).
Mashed = FUBAR
Sorry about the huge post -
Hope this helps!
