Title: Fuel economy tune Post by: jibberjive on October 21, 2011, 03:57:04 AM So my sister just picked up a high mileage '01 tip allroad, and she's looking for as good of fuel economy as she can get. I'm thinking I'm going to try to do a very mild tune with at 11lbs or so of boost, and try to tweak it for good gas mileage. I'm not going to hook a wideband up to the car, so I'm definitely not going to try to go the ragged edge, just see what I can improve and make more efficient. The thoughts of people with various stages of tuning, whether it be stage 2 or big turbo, often talk of better gas mileage, I'm sure there's some efficiency left on the table in more than a few places on the stock tune.
I did a little searching here and didn't see a dedicated topic, but I remember stumbling on some posts a while ago that could relate. Any thoughts on this, or links to good posts/topics that would relate would be sweet! Thoughts?

Title: Re: Fuel economy tune Post by: NOTORIOUS VR on October 21, 2011, 06:12:54 AM you should be able to bump timing somewhat and leave the fueling stock... possibly reduce the fueling in BTS a little in the low load areas but I doubt it will do much.
A little more boost and more timing will probably give you the efficiency boost you're looking for Title: Re: Fuel economy tune Post by: phila_dot on October 21, 2011, 07:27:29 AM There is a lambda lean limit in LAMKO. This map limits requested lambda to 1.
