Hi Andrew,
For the wideband O2 sensor mod:
I bought a PLX M250 Controller like this one. It comes with a narrowband analog output. I didn’t use it because it fixed at 1:14.7 ratio. What I use is the wideband output (0-5V). However, the wideband output is the invert of the narrowband. Also, the wideband is a linear signal and narrowband is more like switching signal. To make the wideband signal looks like narrowband signal, I use a Schmitt Trigger to convert it. By changing the R1 and R2 values in the Schmitt Trigger, I can change the trigger voltage which in turn change the mixture ratio.

Hi all,

I dropped Wayne off last night in Chicago and got home at 2:00 AM. I had a great time at Lacey and this was the first MPG competition that I was ever in.

Andrew, I was great to meet you face to face. You have done a great job with the aero mods and I wish there was more time to check them out.

So I've been "lurking", but this website may just turn into one of my coveted "Favorite Bookmarks" website. Great seeing all the results posted online. The 45 mpg dwindle in comparison to the triple-digit mpgs, but I suppose I take a different approach to economy. All the comfort with none of the drawbacks; cos' wifey has to be comfy!

For me the rally was a gauge to see how well the car would perform under "controlled conditions" without mods. I contemplated inflating the tires, but that would have skewed "normal" driving conditions. The lower speed of 45-55 was a little unrealistic, but still useful enough as a starting point.

(Oh, maybe it's nothing, but I DID replace the stock air filter with a K&N drop-in. Nothing else.)

Question to all who participated, and all those that have tasted blood: Where will we go to next year? IMHO we should integrate more freeway and city driving. A drive to Tacoma, up some of their hills maybe? Maybe a minimum average speed closer to today's tour driving - like 50-60mph? Checkpoints? Maybe stickers on the gas flaps to prevent mid-trip fill-ups?

Flame on modders, flame on!

p.s.: Tires are now up to 34 psi cold - according to the event sponsored tire gauge . Makes me wonder what they were at before! Honda recommends 32 or 33 psi.

Those cars are pretty heavy, and the EX isn't exactly known for it's economy. That and he had his wife/girlfriend/significant-other in the car with him the whole run.
Wife / co-pilot / cop and deer spotter / navigator. All the good things! Can't wait until next year.

Woot! Glad to see a Civic EX STOCK getting that kind of mileage, the car isn't TOO heavy stock (about 2700lbs meh). 45 without mods is pretty damn good, I'm hoping that means with the mods I'm putting on my EX i'll be able to break 50mpg someday! Good job on the rally guys, Congrats with the stock Civic.
