hey,
i was looking at some sites from guys that said that they had to change the computer mapping for the increase in airflow from a new intake such as CAI or Injen. Just wondering if anyone knew if thats true for all performance intakes,just a few and if so how would i go about changing the computer to accept the increased flow?

 

The ECU should automatically adjust. Or you could unplug your battery overnight. I chose not to do so because I'm lazy and didn't feel like resetting all my radio stations.

 

then why do you suppose they did revamp the computer? are they ignorant?

 

Your Mass Air Flow sensor/meter is what tells the ECU how much air is coming into the engine.. so the ECU will change it's mapping over time.

I would reset my ECU and in about 7 days your ECU should have adjusted to the new intake

and Re-mapping a maxima/infintit ECU is not as simple as it sounds

The ECU uses Oxygen sensors and the MAF to adjust the A/F ratio

 

Are you talking about members here or another message board?

 

oh i was on another site and noticed that in his upgrade list, he said that he tuned his computer to accept the airflow change

 

what kind of car was it on the other site?

try and search the internet for an upgraded 1999 infiniti ECU or being able to truly remap your fuel and air ratio's



good luck
