false. when you clear the ecm, it gets reset to base fuel and ignition maps. as you drive, it constantly readjusts until optimum efficiency and lowest emissions are realised.

and even then, it's still constantly readjusting for ambient weather and atmospheric conditions.

so, in other words, you have to reset the ecu after installing any type of modification that can change the amount of air being ingested by the motor, but after that, the ecm reprograms on it's own. of course this is only applicable to 1996+ vehicles.

by pulling the fues and clearing the ecm all the time, you're just running a preprogrammed base fuel and ignition map that gives you minimal performance gain only provided by the new part, in this case being an AEM intake.

what people think is the opposite, mainly because the new noise tricks them into thinking the car is faster. realise that when you go wide open throttle, the ECM always changes over to a factory base fuel and ignition map, referred to as "open loop". only when you're cruising does the ECM run on "closed loop", where it's using all of the sensors to fine tune the fuel map.
