K-pro effect on gas mileage

[teemmy]

Anyone know how adding k-pro to an 04 tsx would affect the car's gas mileage?

depends on tune and mods. Most likely it will go far down because of your driving. otherwise u can tune it to be more economical.

do you have any ballpark figures? I assume that if you tune the car to be more economical you would basically lose power from the car?

If you are going to tune a K-Pro to be more economical, don't even bother investing money into it. There's essentially no point. You're better off with your stock computer + program.

On the other hand, if you're looking to unleash the raw power from the K24 and don't really mind spending $10+ extra dollars a week on fuel, then go for it, and don't be overly modest with the tune.

It would also depend on how you drive the car. You can turbo the car, and still get decent fuel economy by just driving modestly. (I know I wouldn't)

How much more power can you get out of the car by installing k-pro when everything else is stock?

if you're not planning to go all out to extract as much power possible out of the motor, might as well and save you a really big chunk of cash and just get the reflash...

With K-Pro, you can tune and get better fuel economy AND get more power.

This is because the K-Pro has different fuel tables based on how much you are on the throttle and what RPM you are at. Keep in mind that when you are tuning to produce more power you are usually adding ignition and leaning out the air/fuel mixture (taking away fuel). So in a way, taking away fuel will give you more power and get you better gas mileage at the same time. Many people add parts that provide more air and require more fuel (ie, headers, SC), so that is what ends up making their their MPG go down.

After my last tune, in comparision to my Comptech ACM engine management box, my fuel economy improved when at part throttle / cruising. It went down during WOT and while in boost, but it was expected since I went from 320CC injectors to 520CC injectors and added 3 pounds of boost. I gained quite a bit of power though, so it was definitely worth it.

So it's really up to the user. I've heard of some of the RSX guys tuning their AF ratio even higher than 14.7, to allow better than stock fuel economy in certain RPMs.

With that being said, having the K-Pro will probably make you drive faster, so you're MPG will probably stay the same and would even go down if you upgrade other parts and drove agressively a lot. So, it's pretty much up to you and the way you drive. I can get 24-25 mpg on a good day or get like 18 mpg if I drive it like a stole it!

can someone clarify the differences between the reflash and k-pro?
sorry for being so noob

i just want to have more power but still retain good mpg (which i'm sure is everyone's dream too)

I assume u are not 20 yet..... but thats ok. more power=less MPG. That is a very simple formula that will answer a lot of questions Light weight pulleys should help with both, but only u can judge whether the price is just.

actually I am 20 =]

the reflash is a one size fits all tune thats more aggressive than stock and designed to take advantage of bolt ons. even without bolt ons, it lowers vtec crossover and increases midrange power.

K-Pro is a custom tuning application that can be used to tune for specific parts. Cams, intake manifolds, turbo kits etc would benefit from k-pro tuning. Theres more information on these boards about the subject. Thats just a quick rundown.

[Tsx536]

Reflash is static and cannot be changed by the user. K-pro is user programmable.
