whats the point of resetting ecu?
i have been reading in some threads of people reseeting their ecu on occasion, why do you do this?
what i was thinking:
evo ecu learns and if you have been driving slow for a period of time the ecu does not let the engine reach full potential when you decide to slam on gas.

I'm still trying to figure out exactly what it is that the ECU "learns". I always thought everything was based on sensor readings. MAF, coolant temps, O2, knock, CAS..etc. Reset the ECU and those sensors still work the same.

The trouble with that logic is that the ECU will learn what vaules the sensors should be seeing. If you drive around with stock parts for a while and switch out say, your intake, the MAF won't see the same values it was before, triggering a warning to the ECU, causing it to throw a CEL.
Add or change a part, reset. It's the best way to prevent trouble. If you need proof, search for how many people have reset ECUs to fix problems caused by bolt-ons.
