well i have just gotten a swap into my car

specs-1996 gsr swap gsr tranny stock except aftermarket intake sgort ram

car-1996 civic hatchback dx

problem-well my main problem is that i have very poor mpg i get like 8-10 and that is not hitting vtec when i hit vtec its worse.
i went to the shop that did the install and they said that it will be easyier to convert to obd1 and i will have a lot less problems.
now i am wondering will that be better or make more problems.
the ecu i have says p0p it is not a p72.
i am throwing codes also heres what they are

p1337--crankshaft speed sensor no signal
p0135--primary h02s ciruit malfunction sensor 1bank1
p1381--cyp sensor intermittent interuption

future plans- i am planning on going with a reliable turbo setup 6-7 psi

main questions-
now should i just go have my ecu tuned or should i go obd2 or should i not worry since i am going turbo anyways.

 

First, try an OB2A P72 .... if your problems persist, fix them.

After that, get a chipped P28 with custom map when you need to (ie, when you turbo your car).

 

need a p72 ecu

 

so is this a good ecu i have never heard of it before and he also said that its tuned
but i didnt have my o2 sensor hooked up and its still let it engage in vtec so i was thinking if i can just get the ecu tuned better
what do u think?

 

how much u got the ecu for

 

Step 1: Hook up both your O2 sensors
Step 2: Use a P72 ecu

You shouldn't be surprised that you are throwing codes for sensors that aren't functioning properly.

Perform a search for P72 on ebay or on Honda-Tech and you will find tons of for-sale ads.

It would be better for you to get the correct ECU like everyone is telling you to do

 

ok thanks ill get the right ecu and try to sell this one is it worth any money

 

my bad the ecu is a p2p whats that

P2P is for a D16Y8 ('96-00 OBD-2 Civic EX). Your B18C should definitely be running like crap with that.

 

Buy the p72 or get a chipped p28. Both can be had for under 150 easy.

 

how do i get a chipped p28
do i buy it from a store or do i have to buy the ecu then get it chipped.
damn and the shop that sold it to me charged me 200 bucks too for the p2p

 

you gonna have to wire up your crank sensor. on the single cam its like single wire and b series is 2 so you need to wire that in. and for the 02, hook them up

 

wait just called the shop
and they made a good point
my engine hits vtec at 4400 rpm and redlines at 8200 so its just the shell of a p2p
so i just need to get it tuned i guess

 

and wheres the crankshaft sensor because i dont know where it is located

CKP is in the distributor base. It is not replaceable. If it goes bad, you need to source a new distributor.

 

Sounds to me that you need to take it back to the shop and have them fix everything. What shop did you go to anyway? (if you dont to publicly post it can you PM me)

Do you plan on getting the car BAR'd? If so dont even worry about the whole tuning thing (hell if its a stock motor you shouldnt worry about the tuning til you go turbo). Next your swap (being that its the same year as your car) is a 100% plug and play setup. If you still have access to your old motor, take your distributor. You could swap the internals with your GSR dist. and 2 of the codes would be gone. Did you ever have a 2nd o2 sensor?

 

no i have never had a second o2 sensor on my y7
but i still only have one sensor right before the cat.
and i want to get it tuned cause i am getting very bad mpg.
thanks for the help

Huh? All D16Y7s have two O2 sensors, just like every other OBD-2 Honda engine . . .

 

no i just had one in the cat right after the header
