If i flash, or take out the governor, will my mpg increase?
if so, how much and what else will i get?

i have a 99 civic ek d16 all stock.

 

get a obd1 jumper harness and chipped p28 you can get basemap with no governor

 

I don't see how not having a speed governor would increase your fuel economy.

 

is it plug and play, or will i need to tune it?

 

This.

 

first off the car doesn't have a governor and second the car does not have enough power to push past 120 and third the this will not increase fuel economy in anyway.

 

What do you think the rev/speed limiter is? It's nothing but an electronic governor.

 

First of all, this is America!! Not Europe that you can max out in the highway..
second and most important, if you're doing auto x racing or drag racing, aint no where in hell you'll succeed reaching top speed in a STOCK motor. period!

 

Since hes gonna be doing 140mph on the highway, hell get to his destination faster and use less fuel.



/sarcasm

 

So much wrong... don't.. know where... to start...

must.. tear out... eyeballs..

 

Not on a stock motor.

 

Just made my day

 

im new to the car scene. I heard, if you take the govenor out or flash it you can get better mpg. i dont plane on going 120mph anytime soon not even 100.

 

1st, there is no governor. 2nd, what would you change to increase fuel mileage? You don't think the hundreds of engineers made hondas as efficient as they reasonably could? 3rd, how much more fuel efficient would you car be? 1? 2 mpg?

 

what has been seen.

seem pretty new to the whole automobile idea to me...

 

The car is not governed. The engine has a rev limiter, but you will not hit it in 5th gear with a stock motor.
If you modify car, like throw a turbocharged GSR swap in, then you'd have to tune it anyway and you can remove the rev limiter then...though it's not a good idea.

 

what about a intake?

 

what in the hell are you talking about if ur MPG is crappy than do a full tune up.... Cap, Rotor, Plugs, Plug Wires, PCV valve, Clean the IACV, New Air filter oil w/ filter, and Fuel filter i also add BG44k every 10k miles

 

Dont. Ever. Touch. A. Tool set.

 

already did most of that

 

Then your car should be running like a boss and thats about the most you can do to get some serious MPG's out of it.

 

ok thx for the info guys

 

Don't do anything to your d-series unless you rebuild the entire thing with high compression pistons and some solid cams.

Or you turbo it.

Anything else is a total waste.

 

Most people that I hear do N/A builds on their D regret it afterwards. The end results are not impressive.



BOOOOOOOOSTED D FTW!!!

 

For the cost of a gsr swap you can make similar power with a naturally aspirated d-series, that is if you're buying it from a motor importer and not snagging deals on local parts.

N/a d-series isn't bad if you're comfortable with ~150-160whp and 115tq.

It's fun, quick, easy, cheap replacement motors.

For the same money you could easily make 250whp on a d-series. Or the same power on a "fresh" gsr swap.
