Hello. I am getting really bad mpg on my 2004 lancer LS. It has no mods, everything is stock, running good and has had good maintenance.

I get around 8-9 L/KM Which is 18-21MPG. I never hit the throttle hard, normally 1/4 to 1/3 way down. Not going above 60mph. Normally drive with a/c on, but the best I have gotten with a/c off is 21mpg.

I refill tank once a week, I check how many liters it take to refill what I have used that week. Lately has been 8.4 km/l.

The check engine is on, but it is only from a bad front catalytic converter. This should not affect mpg in any way.

I have read stock lancer ecu's run rich. Any way to remap or something to run better mpg? Or anything I could try?
