    I just got a 1997 civic w/ b16a2 swap. The guy tells me it needs p72 ecu to run, bc the p2t ecu (original si ecu?) will not work. The car is retarded slow, gets absolutely no power from 1st to 3rd gear. I have to shift @ ~4K rpm IN EVERY GEAR, which kills mpg ratio. Autozone says that I need a new distributor, spark plugs, o2 sensor and wire set. Should I believe autozone and hand over the money, or believe the guy who sold it to me, who says he's never changed the distributor?

    that first thing you did wrong... autozone over priced and bullshit is what i always get from them
    go to advance auto parts
    they know more
    i work there

    That really all depends on the area- some places AutoZone is better, some Advance etc......

    As for who to trust- I would take the car to someone who knows swaps before taking the word of the guy who sold it to you and obviously doesn't know how to get it to run right or a shop that probably has no idea what's been done to the car. Whoever did the swap probably didn't wire it up correctly.

    yea you are right
    is the ecu from a dohc motor? if not that would be one problem
    but yea talk to peolpe that know swaps and that can actually look at it to see about that wiring

    try this and get back to me
    This article describes how to trick a U.S. OBD2a or OBD2b ecu into thinking a CKF sensor is wired in when there actually is no CKF sensor on the engine.

    What is the CKF sensor?
    The CKF is the Crank Fluctuation Sensor.
    On all 96+ (OBD2) Honda/Acura vehicles, this sensor is integrated onto the oil pump.
    (CKF images soon)

    This trick is mainly aimed to help hybriders who are using a U.S. OBD2a/b ecu in their vehicle, but their motors are lacking a CKF sensor. For example, running an JDM OBD2 engine in a US 96+ vehicle but retaining the US OBD2 ecu. For those that don't know, when using a US OBD2 ecu and the CKF sensor is not wired in, the engine runs like total crap. This trick basically taps the CKF into the CKP signal.

    This wire trick will save you money (around $300) and headaches!


    PROCEDURE

    1. Please refer to the ecu pin out page respective to your OBD2 type and take note of the CKF pin locations:
      OBD2a pin out schematics
      OBD2b pin out schematics
    2. Get 4 Scotch-lock/tap splicers
      Sometimes dubbed 'quick splice', these can be real life savers.
      Get yourself 2 of these bad boys and a pair of pliers for the squeezing-splicing portion of the job.

      [​IMG]
    3. Locate ECU pins

      OBD2a Users:
      This mod requires you to quick splice a total of 4 wires (2 wires per quick splice).
      Locate the blue ecu plug "C":
      [​IMG]
      Now locate pinout C1 (CKFP) and C4 (CYPP) ; using the pliers quick-splice these two wires together as shown:
      [​IMG] [​IMG]
      Then locate pin C11 (CKFM) and C14 (CYPM) and quick-splice these two wires together as shown:
      [​IMG] [​IMG]
      That's it!
      Your finished OBD2a quick-splice job should look something like this:
      [​IMG]

      OBD2b Users:
      This mod requires you to quick splice a total of 4 wires (2 wires per quick splice).
      Locate the blue ecu plug "C":
      [​IMG]
      Now locate pinout C22 (CKFP) and C29 (CYPP) ; using the pliers quick-splice these two wires together as shown:
      [​IMG] [​IMG]
      Then locate pin C30 (CYPM) and C31 (CKFM); quick-splice these two wires together as shown:
      [​IMG] [​IMG]
      That's it!
      Your finished OBD2b quick-splice job should look something like this:

    wow...i havent seen this thread in a while.... wow almost a month.... so if i have the p72 ecu and harness, and given my car is 97 ex w/ 2000 b16a2 engine, the above mentioned procedure would work? man i gotta find this... i'm still working on my problem!!!

    first things first, how fast do you expect it to be? it wont be that fast. it's a heavy car with a low hp engine. if you really want to find out if something is wrong with the power, save your money, go to a shop and pay $30 to get a baseline dyno run. this will show you where your power curves are.

    if you get 130hp to the wheels you are doing good. b16's really aren't going to be a whole lot faster than the sohc vtec. but it is always good to do a full tune up.

    it's not necessarily about being faster than other civics... it's being able to keep up with normal, daily driving traffic. at an uphill stop light, I am the slowest of the pack, seeming like the car is running on 2 cylinders. I just want it running correctly before even assuming i have power to run against other tuners.

    its not the ecu nor a tune-up! i owned an ek hatch with a b18c5 with basic bolt ons( jdm 4-1 header, intake, cat back, complete msd ignition) and the car still ran like crap. im guessing the culprit was the weight of the car. my friends own eg hatches with b18c1 motors and pull on me all day long! i can imagine a b16a2 in an ek! i can take an ek with a b18c1 motor though! just an opinion!!!!

    then you need to get it on a dyno. if you don't have a check engine light, then you need to find it's power and where it's weak.
