So I was curious if anybody would be up for testing this:

Find a freeway entrance ramp, and reset your MPG average and your trip odometer. From a standstill, accelerate using light pressure on the gas pedal, shifting at the speeds indicated in the Honda owner's manual, until you reach 65mph and maintain that speed. Continue to drive until you've covered 3-5 miles, and record your average MPG.

Next, go back to the starting point, and do the exact same thing, except use about 7/8th throttle (not full wide-open throttle). Keep shifting at the relatively low shift points.

Basically, the point is to determine how much fuel economy differs based soley upon the amount of throttle. By controlling for total distance driven (and making sure that you're looking at more than just the acceleration portion), as well as shift points, we can get an idea of the trade off between increased gas consumption whilst accelerating and the amount of time spent engaged in acceleration.

 

Sounds like a good experiment, but one note: Unless your Scangauge has been calibrated (Check the manual for "Adjustment Factor on Fillup") it can read a few MPG one way or the other.
Uncalibrated scangauge fuel economy readings are just "in the ballpark" until you enter the stats into the unit at each fillup.

I would think comparing the two tests to each other using the same car/gauge would be ok, but comparing one car/guage to another would not be accurate.

That being said, I haven't bought my scangauge yet!

 

I would love to help but I have the auto. I would think that open throttle and low shift points would be best. There would be less pumping losses trying to suck air thru a slightly open butterfly.

 

I think that if you get the scan gauge you will be impressed. Not to mention , it's a new toy to play with.

All the best.

 

Yeah, I'd like to get one myself, but it's just an issue of where I'd want to mount it, and worrying about it attracting break-ins.

 

Mine is right next to the driver's A pilar, next to the small window. The windows are tinted and it really can't be seen.

 

How do you run the cord to it? Is it just hanging around there?

 

I still plan to get one.

Can you disconnect the cord from the unit or only from the OBD port?

 

yes, you can unplug from the display unit. actually that is the only place to plug/unplug it. it looks like an ethernet cable.

 

I love mine because it allows me to keep tabs on intake air temp and water temp. I get a lot of questions/comments about it.

 

That's a beautiful job with the install. Did you notice that your driving style changed after getting the gauge?

 

No, the cord goes to the left, and down in the crevice (heh heh, he said crevice) between the door and the dash. From there under the dash to the OBD2 port.

 

a little bit yea. i drive about 50 miles to and fron work everyday via the highway and have started only going about 60 instead of 65 and that seems to make a decent difference. I have one in my truck too. I love the thing. And the fact that all you need to do is plug it in and you don't need to wire up stuff is great.

As far as the bracket, I had that custom made by a member here. I believe he's going to start making them for purchase if you have an after market radio setup like mine, but I'm not sure if he started them yet.
