I got new Yokohama YK580s put on the back. The new tires on the back caused an unstable and loose feeling front, funny thing is that I didn't realize it until about 50 miles in. It happened at 60 mph, thought it was worn suspension at first, since I didn't feel it the first time i drove on the highway with those tires. So that cheated me out of driving my car for a week , instead I was stuck with my dad's auto G35X, I got 29.8 at the highest.

When the tire crap happened, I had let my dad drive the car home so he could see if he could feel it, so he drove with the a/c on and at 75 mph, he got 26.9. That brought down the tank average from almost 36 to 34, then more short trips brought it down further. I filled it up with 407 miles and 12.224 gallons. Thats 33.3 mpg. Lower than two of my previous tanks. I'm going to save my mileage reports for when I have the other part of the commute, but it doesn't look good. Winter gas is around for sure, and I drove faster than usual because traffic was denser, and I wasn't used to my car. Scanguage was also off a few percent, due to the larger diameter wheels I assume. (new tires on the front now)

I recently tried out some air to fuel ratio x gauges with my scangauge, of course none of them worked , and I ran my battery down, so I had to drive and charge it. The result was about 16 mpg. bleh.

Good news time! I finally found the part number for the accord hybrid's rear diffuser and it is $41 at majestic honda. More than i'm willing to pay for its anticipated gas savings. Another thing I discovered about the accord hybrid is that it has an aluminum hood! Ever since feeling an s2000's super light hood, I have wanted an aluminum hood. Now I can have one! Also, I remembered that I can set waze to avoid highways, so I can cut off more than 5 miles off my commute, drive slower, and possibly get better gas mileage. I will have to see if the increased number of stoplights is detrimental to my mileage.

Parts wanted from accord hybrid: Decklid spoiler, hood, and rear diffuser

Unfortunately for me, there are no nearby accord hybrids in my color being parted out. And I learned from my previous accord to not spend lots of money on parts expecting to get that money back in either resale value or gas mileage improvements.

I will be spending this weekend replacing shocks and maybe rechecking the valve clearances, its gotten noisy.

You're getting that high without engine off? :O I must be doing something horribly wrong, I can only average a little over 40 while killing the engine whenever coasting, and I have a more efficient engine that I tuned.

love waze except when it sends me to the feeder road, hit 3 lights, instead of staying on the freeway and taking the correct exit.
aluminum, love that also. there are fantasies of me in the VW stamping room, feeding sheets of aluminum instead of steel.

I do not EOC yet. I want a kill switch, PS delete, and 4.13 EM scanguage update before I do EOC.

I'm getting confused about which trip is which, but i think i got it. I need to post these earlier before i forget.

Commute 1: Forgot what happened, 36.5 mpg.

Commute 2: Tried out a different route. 71% OVER EPA! What's that? Its city epa? Awww. It turned out to be 30 mpg, i calculated an EPA estimated 17.5 mpg from the 27 mph average i had. This was with tons of stoplights, and a dying battery, so no engine off at lights. I don't like that route, back to my old one I guess. Take these trips with a grain of salt, it could be up to 4% off from new tires and winter gas.

Got a new battery after 30 mpg trip because car barely started even when warm. New battery was $126 I actually neglected to check water levels before going to store, so I hope it was really dead. It lasted only 3 years and 10 months, not very good. I'm used to batteries lasting about 8 years.

Guy who replaced battery for me(free/paid with jacked up prices) hooked up something to retain ecu memory , but it had already reset when it got too low during a start . After the new battery, it went back to its usual super fast and awesome sounding starter noise.

Replaced front shocks and took off clutch slave cylinder to clean out debris, car is 100% more enjoyable to drive now!

I'm Back Baby!

Thread revival! Yay! Its been a while since I last updated this thread, so I figured I should update it. Lots of progress has been made, and lots of pictures have been taken. Unfortunately I have not seen big mileage improvements yet, probably because it has been steadily getting colder outside. Last time I drove the car it was 40 degrees F outside.

Lets start in chronological order, so first up is the underside. If you paid attention to my previous posts you would have seen me desiring some sweet hybrid diffuser action. Well, I got one! Click image for larger version

Name:	IMG_2933.JPG
Views:	60
Size:	69.5 KB
ID:	19521 Looks sweet! Installed it in an hour or so, wasn't as simple to install as I thought it would be. Turns out the normal accord doesn't have the holes drilled for it already, so I had to take care of that. Drilling into metal in a car is always scary, but this lead into the spare tire well and was super thin, so I was okay with that. The metal was so thin that I couldn't tap threads into it, so a nut was used instead.

After being tightened down, the entrance angle to the diffuser changed, I don't like that. Might do something about it at some point, like some spacers, but not really high on the list. The underbody before the diffuser isn't horrible, but I imagine it isn't allowing for much diffusion .

Any results from the diffuser have been lost in data noise, haven't noticed better coasting. I'm guessing it needs some underbody trays before it can do its job. A nice side benefit to the diffuser that I didn't notice when I first spotted a hybrid is that it actually mates up with the rear bumper really well, I imagine it severely reduces the parachute effect in the bumper.

The next mod I worked on were some nice wheel boat tails. I brought up what little information I could find about them, used the template, and created these: Click image for larger version

ID:	19527 To minimize road debris risk, I used hot glue and coroplast only, until later on that is. Here is how they looked behind the front wheels, the first place I put them. Click image for larger version

I think that they actually enhance the appearance of the car, anyone else feel that way? I got to test their speedbump impact index on the first test drive, luckily it didn't register . I took them off a day later because they were falling off. Minimal velcro and a poorly placed ziptie on each tail meant they didn't stay on well. Also, in the front they blocked the jack point, so it would have been a PITA to deal with anyways. Too bad, they looked cool up there.

So I put them behind the rear wheels this time, and used a sturdier mounting system this time: L brackets! Yay! Click image for larger version

Results? You know the drill, I don't do testing (yet...?) so I can't narrow down little things. Which means absolutely no improvement noticed. However, I do have an insight (no, the other insight) into why. Thanks to forza 6 I saw the back of an Indycar and their form of wheel boat tails. Take a look: Click image for larger version

See how the tail is open to the wheel well? Guess what my tails aren't? Yep. They are closed in the front. I think it should be open after seeing an indycar, anyone else agree? These things have stumped me for long enough.

After I saw how effective the L brackets were at holding on the boat tails, I decided to finally make some rear tire spats. Unfortunately the L brackets were too long, so the spats had to be mounted away from the floor of the car. I didn't even try these out because I thought they wouldn't help.

Another easy mod up next This one actually went on the car. Upper grill block woohoo! Click image for larger version

I made it out of clear tape so it is really hard to see, just how I like it. The right side is completely blocked, but the left side is only half blocked. You can see where the tape ends right at the transition from radiator fins to the silver edge of the radiator.

This was the first mod in a while where I actually saw some results! Rarity definitely warms up faster. The unintended side effect is that the operating temperature is higher now. The fan will kick on in slower traffic, and I had to take some tape off the first time I drove with it. Good news is that it raised intake temperatures. It was 40 degrees F outside, but 100 in the intake in slow traffic. My usual driving style keeps IAT about 40 degrees above ambient when moving. I cannot report any mileage improvements though.

Undertray, Yay! Pun not intended but welcomed . What a pain to mount though. I kept trying to push the clips through the bumper, undertray and oem undertray. Said screw you to the clips, hello zip tie technician.

I am satisfied that it will stay attached, and am sure it is an improvement over nothing. Excited to see SOMETHING, ANYTHING, the next time I drive it.

nice set of mods there! looks good to me. hope you see some improvement. will be hard to tell which one works and doesn't. hope one doesn't cancel the other one then you'll never know.
