it only does cuz u put yer foot in it more often lol. in reality if u drive the same and re-do yer ecu it will get like 1 or so mpg better

how do u redo your ecu

hotbox05

disconnect yer battery for 15 minutes. it re learns the fuel eq curves. to get best results at first. get yer car hot. then remove batt cable then wait 15 mins then connect and then let idle for like 10 minutes

Good Thread!!
In considering a CAI I had read of possible ECU retuning to set up the CAI. If I bought a CAI (BLITZ or K&N) do I need to get my Xa's ECU tuned? Seemed expensive for very little gain. By the way in the February 2005 edition of Import Tuner is the article of the 215 Hp Xa, (good looking girl but would rather more shot's of the car), had an ancilary reveiw of a Blitz and a K&N, and seemed to like the Blitz. If no CAI am I better off with a foam drop in or a TRD drop in?
