Default Highway Performance Flat

I wonder if all '06 Accord V6's are like this? This EX L I have is a rocket off the line and scats in and out of traffic really well in slow city driving, but get it out on the interstate where the new speed limit is 75, it seems to be straining. The other day I went across town and was on the interstate for a few miles. I was trying to pass an 18 wheeler, and did but it took all I could give it to get it done. It got up to 90 during the pass, but it felt like top speed for it and was straining it's guts out to do that. That old '05 Accord Hybrid I had could cruise at 90 with no strain and I even had it up to 120 per a time or two!

Wonder why these '06's are geared for better performance in town, but not for overall performance on the road as well, like the '05 hybrid was? I do have a K&N filter on it and think about going back to the stock filter, but I will expect a decrease in in town performance, and probably no improvement for highway either. I doubt there is anything a mechanic could do to balance out the performance spectrum any better, but I wish they could. I've thought of getting turbo mufflers, but I figure that would only make matters worse. It has stock mufflers now and I assume the catalytics are okay. It has about 29k miles on it now.

Automatic?

I'll use my 10 Accord EX-L V6 to offer an answer. The V6 have two modes. At WOT, it's a beast (for a large family car). 0-60 in 6.5 sec auto trans. In other modes, it seems like no one is home under the hood. What happened to the Acura Legend feel that I love?

The Accord Hybrid was a strange bird. Honda actually wanted to prove a point and that Hybrids can be powerful, fast, and offer performance. That's why it failed because Hybrid owners care more about MPG, not 0-60. Electric motor offers that feeling of torque that is addicting.

Putting this together, the Accord V6 (auto) is not meant to be a performance car, period. It feels like a I4 most of the time. That's how it's programmed, tuned, and designed. But it is powerful, smooth, and fast for the 98% the driving situation on the road.

If one wants a spirited Honda J-V6 powered car, there is Acura.

Automatic! Thanks for a very informative reply, GoLowDrew. They definitely proved the hybrids could scat. I would have never parted with that car, but some woman driver, probably talking on her cell phone failed to yield right of way at an intersection a year ago last October and totalled both my '05 and her Cadillac! I did my best to get the dealership to find another hybrid, but they just couldn't come up with a good replacement. I didn't want a Ford, Chevy or American junk, I wanted another Honda, which of course, I got. BTW, what is WOT? Wonder if I can get it set to stay in the scat mode of WOT? lol! It's a running car, but just lacks a tad on the open road sometimes. It loves cold weather and hauls it good when it's cold. I also use a mix of mid range octane and V Power octane of Shell gas. That also seems to be a good combination for better perf. Strange, but it seems to help.

Wide Open Throttle.

Did your car kick down when you tried to pass that truck?

Knowing this now, I wish I new something I could do to enhance the power. A different type muffler, going back to the stock air filter, I don't know. There may be nothing anyone can do. I don't have a lot of money to spend on a car, not on Medicare yet, but just looking for a cheap "pepper upper" if there is one. :-)

For certain it is weather sensitive. If the barometer and humidity are right, it's a bomb, but if not, you can tell the difference. Most times, it accelerates (to me) better than the old hybrid, feels lighter. Just needs that highway zip that it doesn't have sometimes.

There is the traditional recommendation of intake, and cat back exhaust. From your responses, I'm guessing you are a mature owner, and not sure you want your car sounding like a ride for a teenager.

A bit more "spirit" can be uncork on a Honda V6.

Have you also tried a higher octane gas, like 91? I'm not a fan of using anything more than 87, but I have noticed my engine "feels better" when I do run with it a few times.

There is a thread here in the accord section where owners mentioned the J35 V6 actually produce a power increase with continue use of higher octane gas. The results was dyno, so it's not just an opinion by feel.

Or mabye you can test drive a Acura TL and see if that's the driving feel you are really looking for.

I use 91+ all the time and it DOES make a difference. the ecu will take into account the added octane and NOT retard the timing as much as if it detected conditions with 87.

87 works fine and the engine does need anything more than that... unless you want a more lively throttle response.

When you are going for that pass... stamp that gas pedal. it will kick down and you should feel the max the car has to offer... if you try and squeeze the throttle, you wont get a kick down and your passing time will increase.

On additional thing you can do is to reset the ECU, Acura j series owners swear by this to get the car feeling proper based on the fact that the ecu is learning your driving patterns. I have not tried it myself because I have a Manual and my car runs fine.

---------------------------------------------------------------------------------------------------------------------------------------------


The Throttle is "Drive By Wire" and adapts to your particular driving
style. Do a TBA Throttle body adaptation.

1. Get in your car, it doesn't matter if you close the door or not.

2. Turn the key to the on (not start) position, the position just before the starter
turns over.

3. Press the gas pedal to the floor with the key in the "on" position.

4. Hold the pedal to the floor for five seconds, then turn the key back
to the "off" position (don't remove the key), then release the gas
pedal.

5. Wait 2 mins. for a full alignment.

6. Drive the car as you always do.

Depending on your driving style, this may or may not be a big factor. I do a lot of city driving so
I noticed a big change after erasing my history. It is not hard to do this, just follow the instructions -

Key on, pedal down, 5 sec, key off pedal up, wait 2
minutes.

Keep the key in for the entire thing.

I'm sitting here laughing in amazement at that reset deal, MSchu! Not laughing at you or the method but a kind of "Wow, that is so cool" type laugh! I'm gonna print this off and try it, by cracky! Thanks, and I'll let you know how this goes. This erases history? Neat! Most of my driving is city driving too.

If I use 91 octane for very long which for me is V-Power by Shell, it seems to become more sluggish, but alternating back and forth between medium octane 89 and V Power seems to be the right mix. Kind of a half tank of each. Probably weird, but what seems to work for me.

you cant really judge by the butt dyno... it is wildly inaccurate.

also, to do the reset, you need to have a throttle by wire model j series.

I don't know what type throttle this is. I've never needed to know I guess. It may not even work if it's not the wire model J series then. All I do know is it's a Honda Accord EX L 3.0L V-6.

Yes, I am in my 60's, but still like a teenager in wanting good performance, but not a lot of noise. I'm open for suggestions for uncorking that pup, if it's not real spendy.

I'm just posting links/info. I'm only using ebay because it's quick. I'm not recommending them as vedors.

Catback exhaust - I recommend Apexi WS2.
http://www.ebay.com/itm/APEXI-WS2-CATBACK-DUAL-EXHAUST-03-07-ACCORD-COUPE-V6-/190562037533?pt=Motors_Car_Truck_Parts_Accessories &fits=Model%3AAccord&hash=item2c5e61ef1d&vxp=mt r

As a former owner, it is the "quietest" performance exhaust. It's expensive. Alternative would be something like Megan Racing OE. Half the price.
http://www.ebay.com/itm/MEGAN-STAINLESS-TIP-OE-RS-CATBACK-EXHAUST-ACCORD-V6-COUPE-2-door-08-CS2-/270825818743?pt=Motors_Car_Truck_Parts_Accessories &fits=Model%3AAccord&hash=item3f0e7a0a77&vxp=mt r

The links are for coupes, you'll have to find the sedan version and correct year.

Intake

K & N is a good (famous) brand. I use their drop in filter (no performance gain). Here is a good short ram intake.
http://www.ebay.com/itm/K-N-Typhoon-Air-Intake-System-08-11-Honda-Accord-2-4-4cyl-Black-/260968384096?pt=Motors_Car_Truck_Parts_Accessories &fits=Model%3AAccord&hash=item3cc2ed8660&vxp=mt r

If that's too expensive, there are cheaper ones for $70+.

I have an 03 V6 auto, and it does loose a little with warmer weather, but I guess all engines do that to some degree. If you want it to really go, you have to make sure it gets the message (pedal to the floor). If it doesn't downshift, you aren't getting much acceleration. I do find it cruises at 80mph with no effort on the highway, and that's the best part of the V6 engine.

there is a pressure switch upgrade for the transmission TL j series guys... I dont see why it would be any different for the accord other than this is a much older version (J30)

The dealership used to let me know if there were updates to software on the '05, but nothing heard about a transmission updgrade on the '06.

This '06 V6 does pretty good up to around 80, but then the struggle begins, any higher!

I just emailed the dealership to see if it is due any updates. The ones I would get for the '05 would always improve performance with each one.

Yep, they just raised the open road speed limit to 75, and in Texas, that means get movin' or get flattened! Most of 'em the other day were cruising at 85-90 or more, even 18 wheelers. Give 'em an inch, they'll drive a foot... buried past the floorboard.
With gas prices going off the charts, I'd say that was a dumb move. If anything, the speed limit should have been reduced back to 60 or 65.

I once consider meeting a relative on the other side of TX. Big state. Gas prices or not, it would be painful to get from one side to the other at 60 or 65. So...ok, I can see why "going fast" is almost a necessity.

Note: I'm not saying we should break the law, but you know what I mean.
