Hypothetically, would it be possible to tune a car to get better milage than what it came with from the factory? Lower the boost, take out some fuel?

QUOTE (Chicago_DSM @ Dec 13 2006, 05:25 PM) I get horrible gas mileage...I have a pretty heavy right foot, but for the most part on normal trips I notice my mpg is way low... I attempt to tune my low throttle settings leaner, for better gas mileage/cruising purposes, but I have had no luck....With the mitsu ecu doing its job, no matter how lean I set my safc settings, my wideband always finds its way back to 14.7 during cruise....At idle, thats a different story... Maybe my o2 sensor is bad? Well, the logger says otherwise....Sometimes the o2 cycles perfectly normal like it should when I cruise and idle, then a little later it will stay perfectly still at .001v which clearly is a sign of a dead/dying sensor....Who knows why, but the fact that it does cycle has stopped me from spending more cash on a new unit... I guess its time for me to change my oil regardless, and I could use some more tire pressure Have you hooked up you UEGO to your ECU? -------------------- Yeah!!!!!!!!!!! AND WASH THAT THING OFF BEFORE YOU COME BACK!!! GROSS

All of that and I don't know what I want to do next. |
