yes I put alot of money into the car but hey its a honda. BTW no rust at all.

15" Rota X-cross with candy lip qith Kumho Ecsta AST's inflated to 36 psi cold.

Now i drive exactly 197 miles everyday. I have a brand new cobalt (blah [freak]in blah garbage) so i know the mileage is correct and not off on the honda. plus my gps is matched correctly with my speedo. So there are no calibration issues with the shocker number im gonna give you

After all this garbage was done to the car I drove it on a couple trip and got some numbers, along with my work drive.

My last MPG way 47 MPG. FORTY-SEVEN.

Now. Since i have gotten this much greed has reard abound. Can i get more?

i was wondering is crome would be able to touc hthis 0bd0 ECU. maybe throw a resistor somewhere. Im waiting on this Hydro thread to be complete. Or shoudl ijsut leave it alone. i have seen people get 54 mpg in a Crx. Dont bash me pleez.

 

47 is nothing to be ashamed of, but there is also no shame in wanting more. However, you won't be able to chip your ecu with crome, it's an OBDI program.

If it doesn't have carbs or vtec then it's not jdm.

 

i have a 91 crx si with a rebuilt (i think) d16 and my tranny busted so i threw in a hf tranny that i had around and it has much longer gears and i was getting 47 around town. i never calibrated it on the highway but you could imagine it was in the 50 something.. at 70 mph i was at 1700 rpm or so.. but now i have a c5 in it so those days are over.

 

Yeah, i get about the same in my crx, maybe a bit higher (around 55 was the last i calculated). The only thing you can really do to get better mileage outside of swapping major parts (tranny, like someone mentioned earlier) is doing a tune up, spark plugs, wires, dizzy cap. Run some injector cleaner through the car. Should see your mpg go up a little.

 

Well about this JDM motor, i got it from japan. So i called it JDM. im sure they had cars without Vtec. But i think ido need a new tranny. Hf tranny. ima kind of a a n00b at the tranny segment, where is this from?

You said it was stock, any 1.5L EF engine in Japan was carbed.

Yes he has a jdm motor but that doesn't mean you can't run them without the carbs.

My hatch has a d15b in it with the stock dpfi manifold on it
