Improvements for my commute to school

Ok, I'll be serious. New spark plugs, new air filter, and properly inflated tires. Not much more you really can do. It will take a while to recoup what you spend on a fancy whatchamacallit, getting a few more MPG, if you ever really do. The other way to get better gas MPG is as was said before, back of the throttle a bit, it really makes a diff.

+1

When you go uphill, let the speed drop and when coming down let it speed up. Without playing with the throttle. You'll stay in closed loop longer and get better mileage too.

remove your stock intake muffler. drill out the intake for the airbox with a 2.5" bit. Remove the restrictor going from the airbox into the intake. Replace muffler with a higher flowing muffler.

These changes will help a little with power and mpg.

After that, lower the car but retain stock tire size.

Fit a lower belly tray.

buy a prius?

an apexi neo. lean out ur a/f map.

does it intercept the o2 sensors output? if not when in closed loop, which he will be most of the time the ecu will bring the a/f right back where it should be.

it hooks into your ecu, i noticed a difference considering i got 38 mpg with 50/50 city/hwy. i had it hooked up before a 430 mile trip, never took down my mileage but i know my tank took me alot farther as i do make that trip frequently. i can get more mileage readings if you want but it IMO made a huge difference. sorry i cant answer your question tho as i honestly dont know.

yes it will work in open loop, mostly hard acceleration and idle to cruising speed which mostly happens during city driving. It also does help if you do a lot of passing and play with the throttle a lot. But in closed loop with the output of the oxygen sensors being read by the ECU, all modifications will be nullified.

i dunno, i got a hi throttle and a low throttle setting. the low throttle for like cruisin and such and the hi throttle for accelerating. i know the neo is not designed to really make power but rather help you adjust ur a/f maps to lean out more than enrichen. anywho you may be right...

f ck prius, i can beat its gas milege in my aveo on the highway

def. on the hwy prius's suck. their greatest potential is in city driving.
