WTFF?!

I've noticed this ever since i bought the car but always forgot to bring it up here.Is it just me?!!?80mph at 4000 and 65-70at 3500 is NOT cool.Both for mpg and comfort.

Is there a TSB about this from Honda?

 

That's the way the car's designed -- every 5MT is doing 4k@80. There's no TSB b/c there's nothing to fix.

 

There are a couple of companies that make different gearing for the Fit but they will only exacerbate that issue, as they are meant for better accel not lower rpm.

It's just the way it is on the MT.

 

shiiett,ecu reflash will do the job.

i dont remember being over 3000rpm in my old civic in 5th

 

Nope, the car's geared to run at that speed, ECU isn't going to have anything to do with it. Quite honestly, what's the big deal? Lots of cars are exactly the same -- my '05 xB ran 4k@80 as well. You're still getting excellent MPG and better highway performance to boot, why's that bad?

 

Chikubi is right. The manual trans is geared a bit low, and your RPMs are typical.
The automatic is geared higher, better suited for freeway driving. The manual is better off the line and in the city.
This has been covered ad nauseum in previous threads; give it a search and you will see everyone's opinions.
Your car can take the high revs. Keep your oil changes up to date.
Best to you.

 

Same as my 1986 Civic Si, and it ran for 300,000 miles, mostly at speeds above that. It's designed to take it. I changed oil every 2500 miles, but oil was cheap then too, and probably not as good as what we have today.

 

Define "comfort". I find cruising at high RPMs very comfy; on street or on track.

As for MPG, where is your data that supports you have had a significant loss as a direct result of this? It takes more than RPM to consume more fuel. Your right foot is what indicates more fuel being added to the engine.

Your driving area is going to have an affect on this. If you are going up and down hills all the time, expect less mpg than someone who drives on straight, flat surfaces all the time. Vehicle weight, aerodynamics, etc...

 

not sure about you guys but I've never seen an 80 MPH speed limit... problem solved

 

I would like to see less highway rpm. With a power upgrade from say a super or turbo charger the final drive could be less extreme. Think any final drive from another Honda would work?

 

its normal... i dont really mind it... i like how it sounds, and were till getting killer MPG

 

so funny to me how some people freak out about high rpm. Unless your used to driving american cars its 100% normal. A fit or civic at 2500 or 3k at 80 would NOT get up hills or be able to pass with out down shifting. These cars are designed to rev reliably and its no worse then driving at 2k. My Civic now is at 3400 at 60mph and at 80 haha like 4600. My 04 Si was the same way 3k at 60 4k at 75. Its 100% normal i dont know why its a problem

 

I just find it annoying that im smack dab in the middle of my power band when im CRUISING

 

You just answered your own question there chief

 

You've never been on an interstate that has a 70mph speed limit?
And dont even start with im risking lives by speeding talk

 

I'm not freakin out,just annoyed.And ive never owned an american car and probably never will.

It's retarded though,you're not supposed to pass or climb hills in 5th,it's for cruising.

 

I had my Fit reving near redline around 5500 rpm going at 120km/h (or around 75mph) for a extended amount of driving, but I was going up a very steep mountain. I was worry if the extended high rev would hurt the engine, but a little voice in my head told me Honda design the car for high reving and after that trip, I actually experience better mileage!!

 

4,000rpm on the highway is normal for imports, but it's not normal for a car that has such a low redline. If I were at 4,000rpm AND had an 8,000rpm redline, I would consider it normal. We're at 2/3 of our total available rpm when cruising. As for the fuel mileage, there are many threads of people with the Scangauge that shows their economy drops drastically at higher speeds. Know way to know if that's due to the motor working so hard or wind resistance without doing a final drive swap and seeing the results.

If there's a final drive that is numerically lower that will fit, I'd be willing to try it.

 

THANK YOU!!!!!

 

Bottom line.....it's normal and short of major transmission modification, there ain't a damn thing you can do about it.
