Im trying to tune my S300 for the best gas mileage while maintaining full performance (at full throttle). First ,what kind of MPG are you guys getting on 91 octane? Looking at my 3bar boost table while cruzing I spend most time between 2250 - 3500 rpm and stay in columns 2 - 6 (with no boost). What fuel values do you have in these cells? I want to pull fuel from my "cruzing range" im just not sure how much. How can I tell if its getting too lean or starting to knock? I know its rich cuz im getting about 16 mpg on 91 and I was getting 22 on E85!!!

Get a wideband o2 sensor. It will tell you what you need to know.

I just bought a plx-m300te. It works extremely well. Up to column 6 you should be running at 14.7:1 ratio. That is perfect stoichiometric ratio and will net you the best gas milage your car will make.

i was getting about 27mpg around town occasionally boosting. i had crusing a/f around 15.3-15.5:1 which IMO is 17inhg to 25inhg. if you dont have a wideband, you shouldnt be adjusting anything. oh i run a plx as well

i have a aem wideband and havent had any problems, my friend on the other hand bought his new and went bad in a week and had to send it back to aem and get it a new one, but they paid shipping and everything so it was cool but thats the only problem i've heard of


so buy a wideband, then tune...
