ZX2 - 507 miles, 45.6mpg

[moorecomp]

Set new personal bests this tank. I knew I was doing very well when the low fuel light did not come on until 407 miles. Had to go for 500 miles. No worries. 507 miles on 11.1 gallons (12 gallon tank). Maximum EOC and keeping the tires aired to the summer pressure of 44psi helped. Next project is a Home Depot air dam.

Sweet!! Good to see you steping it up this year. Air Dam will help Post up some new pic's of your latest mods!!

Check the team standings. I believe our TeamZX2 has the highest percentage over EPA of all the teams

On a side note, I got lean burn hooked up and working tonight, still got bugs to work out, but the potential gain is tremendous. I saw a 27% increase in my 50mph mpg tonight!

I have to stop and get the lawn edging from HD still. I did buy a new O2 sensor but have yet to change it out. It looks like I have to remove the power steering pump and mount to get a socket on it. I am still running with the air line disconnected, and it just seems to work. I have been changing the way I look at the MPGuino, I run with it set to large current displayed, and try to keep my current reading as high above tank as possible. EOC whenever I can, if even for short times. I don't drive slower than the SL unless no one is behind me, and most of the time I am at 55mph. Could be a good summer!

Rent the O2 socket set from Autozone (free rental if you return it) and you will be able to get the O2 sensor out without moving the PS pump. Although it's not hard to move the pump anyways.
I'd say the vacuum line trick works for real, you can check my fuel logs. It has recovered some, but most due to cleaning the MAF, which you should definatly do. Clean the TB while you got it appart. I wonder how well I would do now if I disconected it again
I run 50mph on the highway...not much different from 55, I just like 50 better.
I'm excited to see your progress! Now that 45 is possible, 50 is reasonable

For me the air dam was definitely the most bang for the buck. 2 mpg difference for me and cost was nothing.
