I just installed a MAF sensor, and reset ecu.Is this the same as reprograming ecu,or just resetting it is fine? thanks.If I need to reprogram it,How do I go about doing that?.thanks

I would post this in our Pathfinder/QX4 forum as well - you're more likely to get a good response there.

I'm not sure when Nissan changed their practice from making extremely accurate MAFs to making sloppy MAFs that required the ECU to learn the range they're outputting when the MAF is replaced. The FSM might tell you... http://www.nicoclub.com/FSM/
