would i get more mileage if....

[DjM_coupe]

i think the p12 ecu plays part in it,

and dude wats your problem everyone especially deevegote answered your question

x2 people on here are tryin to help you dont just lash out on people for no reason...especially if you dont know em...its just not cool...everyone knows adding headers and intake with no tuning kills ur mileage..common sense..more air=more fuel

[Gotz Cb7]

I wouldn't say a short-ram would be known as more air. I see it as.....better flow. Iuno, I noticed a difference with it on. As long as you drive like a sane person though.

[deevergote]

nah,the only part worthwhile that HE can take.

If you don't have a 3rd gen Prelude to use any other parts from that car on, then there are no parts worth taking from it other than that steering wheel.

Go ahead. Take the ECU, the wheels, the motor... take it all. Have fun using it on the CB7.



Or you were correcting my sentence structure? I assure you... "you" wasn't directed to anyone in particular. "you" was the universal '"you" as a CB7 owner'. The 3rd gen Prelude steering wheel is the only worthwhile part for a CB7 owner to take. How's that?

run rich? how, if the O2 sensor will still run the same air/fuel ratio it's programmed to run at.

The o2 sensor only reads oxygen content in the exhaust gas. It is not programmed to do anything. When the ECU reads more oxygen content (more/denser air means more oxygen) it gives more fuel to prevent a lean condition. It has been my experience, and the experience of others, that the ECU tends to overcompensate when the basic airflow mods are added, and you find yourself burning more fuel than necessary.

I was getting about 24mpg until I had my ECU tuned. Now I get 32. That was a stock P13, which are notorious for running rich anyway (now a chipped P28).

imo and experiences an aftermarket intake will increase your mpg if you continue to drive it the same way. it has the potential for better mileage because whats its doing is really not adding more air but your lessening your pumping losses

[deevergote]

An aftermarket intake with a stock exhaust still keeps roughly the same powerband. The exhaust (and header if you add that) usually raise the powerband a bit, making it rather soggy down low. People generally rev higher with those things.

So yes, JUST an intake can cause an increase in MPG. It also doesn't create all that much more airflow, because the engine can only take in what it can push out. You'll probably still use more fuel, but due to the higher efficiency of the intake over the stock unit, it evens out (and can even be better). I know a few people with an intake only, and they DO see an increase. I saw 1mpg on my GTP as well.

I'm seeing at least 2mpg with my DYI ram intake IN THE CITY.

Haven't even gotten a chance to drive on the highway yet, so I don't know that info.

It was worth the $26 to install it for the MPG gain

hey not trying to thread jack but this is abotu mileage, i have headers and exhaust and i notice the drop in gas mileage soyour sayign i can get teh stock ecu tuned for better gas, and i can smell its ru nning richer then before. thanks
