Ok, well my brake light just started coming on in the past two days. Even with the hand brake off. The brakes seem fine and are working like normal but the light is bugging me. Also, I have an SOHC ZC motor with all the stock very very restricting D15B2 parts on it. I mean, I looked at the thing that says DPFI or whatever and I don't know how the throttle body opening can possibly be that small. Anyway, the car is soooooo slow that it's absolutely no fun to drive and it takes literally an hour to get to 60. I want to just give it the 120 horsepower it's supposed to have because I am definately sure that with all those restrictions it probably has that pathetic 92. Even though 120 isn't exactly a lot either but would probably get me around a little quicker. Lastly, I do not want my gas mileage to suffer. I get about 29-31 mpg which is way lower than you guys seem to get already, I don't need any worse. And nothing rice like those stupid Greddy exhausts and Apexi exhausts that sound like a can of bees in a can. I figure a stock muffler will do. I also don't want to spend too much money because it's my commuter car.

 

Check your brake fluid level.

Put a z6 or some **** in the car, 120hp right there, my friend gets 40 mpg on his, just take care of the car and use your head while driving.

 

SOHC ZC have 120hp out of factory. Convert to MPFI and you will notice the difference. I get my SOHC ZC into the 15s at the 1/4.

And I'm using a stock 1.5L exhaust manifold. I'm thinking of buying a junker header for now before I go turbo.

DPFI SUCKS!

Do a tune up...29mpg is worse then when I beat on mine 24/7. I get about 32mpg when I beat, 40-45 when I don't, on Si tranny.

 

So, what does it take to convert to MPFI? Also, the car has been tuned up and I even seafoamed everything. I shift like so: 1st-2nd is 15-20 mph, 2nd-3rd is 25-30 mph, 3rd-4th is 35-40 mph, and 4th-5th is 45-55mph.

Lately I've been using the AC on full blast a lot and only getting 28.9-ish. Without the AC I get about 31-32 in the winter months.

to convert your car to mpfi i just takes a resistor box and 2 wires into the ecu do a search on it and im sure u will find all the info you need

 

I checked my brake fluid level and it is full. The light comes on when it's cold (morning) or when I push the brake really hard to try and stop quickly. What else could the light be a sign of?

 

You must not have enough fluid, cause the civic did that when it needed a brake job, the fluid was slow, after the brake job I added like... 100 ml of fluid maybe.
