b16 fuel problem

[b16ftw]

alright... so i have a b16 in my 95 civic. it has horrible gas milage. i think getting a map sensor will help that out significantly. but there isn't any plug for it in the harness. i'm guessing i have to wire it directly to the ecu which doesn't sound like any fun. any help would be greatly appreciated.

how is there not a plug for the MAP sensor? that makes no sense at all. hell, how are you running it without a MAP sensor? I guess, if there really isn't one, which honestly doesn't sound right to me, just find a pinout of your ECU, run the wiring to the proper place in the ECU plug and go to town...

i know right?? i have no idea how its running! but there is no map sensor that's one thing i'm sure of. and it's running up like 400 dollar a month gas bills.

any idea which ecu you're running? I have a lot of pinouts saved on a CD from doing swaps and stuff, so I can look and see if I have it, depending on which ECU

[b16ftw]

i believe it's a p30. that would be great if you could give me one.

What kinda gas mileage are we talking about? Mine only ever got like 25mpg at best.

OK, the map sensor is on pin d17...it should be a pink and white wire, and then I attached a diagram of the plugs for ya.

[b16ftw]

thanks that should help out alot. where do the other wires go though. theres three wires for the map sensor do they all go in the same one?? i really dont know anything about wiring up stuff.

haha 25mpg?? wow. i wish.... no im nowhere near that. probably like 10mpg?? haha. yeah. its that bad.

i dont think it will run at all without a map sensor!

[b16ftw]

umm well it is and the map sensors no where to be found...

[b16ftw]

ok i found that pink wire in d17... im not sure where it leads to. i still dont know where the other wires on the map sensor would go. there are three pins in the map sensor.
