    Well guys thanks for the nice welcome!!

    I just dropped it of at the shop to get a DOHC ZC motor installed! they said it will be done in 3 days. I will post pics soon as it gets back!

    I am getting the ZC full motor and tranny, its coming off a jdm front clip that was imported at a shop I went to. The only thing that will not be jdm is the ECU, I am gonna run a PM6 mod with a higher rev limiter.

    I had a d15 in there, it still runs strong but runs hot, mechanic said its a leaking headgasket and a bad water pump.

    mid wing wasnt that hard was it :D

    I highly advise that you change to a PM7 ECU, far better ECU than the PM6, my shuttle ran like shit on the PM6 but the PM7 made me open my eyes, can't believe how much quicker she is with it.

    WASn't hard at all, I needed to kinda force fit it, because there was a slight arc towards the center, but its all good now.

    I am running a PG7 ECU, I do have a Euro PM7 sitting at work right now, but I have read that since I have a USDM Honda, people have had problems with rough idle when plugging in a euro PM7. I will try it when I have a chance.
  • Hey guys, I like some of the accessories that some of you have done on your wagons, I apologize in advance for not being original and copying some of you, ei: MidWing, maybe a SIR front bumper, rear fogs, CRV wing, etc...

    Just tried the Euro PM7 on my USDM wagon, it doesn't work. Idles rough and no throttle response. I read on another forum about this problem. Basically anything that has ends in -A031 (EURO) won't work on any car that has a Catalytic converter. I will try and find that post and put a link to it on the Engine topic.
  • That is odd considering the CRX's I have had over here in Germany have cats. Can you send me a PM with the numbers from your ECU and I will check it with an ECU from a German CRX. My buddy still has a CRX and his has a cat too.
  • I'm not so sure it has much to do with the cat. We tried the JDM PM7 on his 88 RT wagon and it did he same.... idle wasn't good. A couple months later we put in a ZC, and then that PM7 was perfect for it and we were still using the cat. I suspect it has more to do with the twin cam. not sure if the injectors are the same, but if they are a different size or pulse width (duration) that would do it.

    On the 3rd gen Si, I know have to use the injectors from a twin cam if you use the ecu, and then it works, otherwise the idle is the same problem you experienced.
  • K guys here is what I found on the the euro spec pm7 ECU. I was wrong about the cat. It has to do about the O2 sensor or something.

    ECU# 37820-PM7-E031
    Check this out, tell me what you guys think? I found a site that explains the differences from the JDM and euro PM7 ecu's.
    Brief overview of the Si ECU

    The ECU or "Engine Control Unit" for the US or European Spec CRX and Integra are similar but differ in there code. All JDM models are limited to 117mph. I have changed my 88 Si ECU to a 90 Si ECU because of the better fuel and ignition mappings. In simple terms it goes better from 3-5000rpms and revs much smoother to the redline. I also found it makes it easier to drive off from a stand still, much more progressive throttle response low down the rev band.

    European and JDM Differences in the ECU

    JDM Models are what's known as closed loop ECU's. They use an oxygen sensor in the exhaust manifold to monitor oxygen content. This will tell the ECU if the fuel mixture is too rich or too weak. Using this input the ECU will alter the fuel mixture on the fly to try and keep the ratio at 14:1 or 14 parts air for each part fuel. The system is designed to stay at this ratio because catalytic converters work best in those conditions. Now pro's and con's. The advantage is your fuel mixture will allways be set right, even if you fit an aftermarket intake the ECU will compensate the difference but only to a certain degree. The downside is you cant force higher fueling rates for highly modified engines. In order to do that you have to get the ECU re-programmed, because european models dont use this system they isnt anybody who can unfortunetly.

    European Models dont have an oxygen sensor, instead they have a manual idle mixture adjustment clipped onto the side of the ECU. Its basically just a variable resistor, you can only set it if you have a Co meter monitoring your exhaust gases. From there the ECU knows how much to increase the fueling at higher revs and loads by the tables in the ECU. This makes altering the ECU much easier because all you have to do is alter the tables in the EPROM chip. i.e. superchips. The eueopean ECU also has an atmospheric pressure sensor located beside the glove box which the JDM's dont have. There is also another sensor attached to the bulkhead with two vacume lines connecting into the back of the intake manifold. I am yet to figure out what it does.

    The ECU gathers information from the following sensors,

    Oxygen Sensor : The Oxygen sensor or O2 sensor located on the exhaust manifold is used to measure the oxygen content in the exhaust gases. It outputs a variable voltage signal from 0.1 volts to 0.9 volts. 0.1 being High Oxygen, Lean Mixture and 0.9 being Low Oxygen, Rich Mixture, the ECU monitors this variable voltage to alter the air/fuel mixture. This is done by altering the pulse width to the fuel injectors, which is basically the time they remain open. The ECU tries to maintain a mixture of 14.7 parts air to 1 part fuel at all times. The oxygen sensor produces no voltage during the initial warm up period, only when the sensor reaches about 316 degrees Celsius it starts to give out a signal. After the engine reaches normal operating temperature OR has been running for 2 or more minutes AND if the oxygen sensor is producing a steady voltage below .45 at 1,500rpms or greater the ECU will set a Code 1. Code 1 meaning all is well. During the initial warm up period the ECU runs in an "open loop mode" where it controls fuel delivery accordance with a programmed default valve instead of by feedback information from the oxygen sensor. If the Oxygen sensor is unplugged or faulty the ECU will stay in "open loop mode".

    Manifold Absolute Pressure : The MAP sensor monitors the pressure in the intake manifold. This signal will vary according to the engines speed and load. It produces a variable voltage of 1.0volts to 1.5 volts at closed throttle (high vacuum), and 4.0volts to 4.5volts at wide throttle (low vacuum). The ECU uses this signal to control fuel delivery and ignition timing.

    Cylinder Position Sensor : The Cylinder position sensor determines the position of the cylinder for sequential fuel injection. It is located on the end of the exhaust cam shaft.

    Crank Angle Sensor : The crank angle sensor is used to control the timing for the fuel injection and ignition on each cylinder. It also detects the engine RPM speed. This sensor is located inside the distributor.

    Top Dead Centre : The Top Dead Centre sensor determines the engine's position during starting. (cranking) This is also located in the distributor.

    Coolant Temperature Sensor : The coolant temperature sensor produces a resistance of 2,200-2,700ohms when the engine is cold and 280-350 ohms when the engine is at normal operating temperature. It is located under the distributor on the engine block. (It’s the bigger one of the two sensors)

    Throttle Position Sensor : Produces a voltage that varies from 0.5volts to 4.5volts from closed to wide-open throttle. A fixed part of the throttle body.

    Intake Air Temperature : Produces a resistance of 1,000-4,000ohms depending on air temperature. Located on the intake manifold above the alternator.

    Vehicle Speed Sensor : Is located at the back of the gearbox, it produces a pulsing voltage signal when the vehicle is moving over 3mph. It’s a little unclear as to why the ECU needs to know this on non vtec engines. It is however the means for the speed limiter on an Si to monitor the vehicle speed.

    Catalytic Converter Sensor : Is located on the exhaust after the converter. It is mainly used just for the warning light on the bashboard, it lights up if it is unhappy about the content of the air or if the converter is running too hot. Isn't actually connected to the ECU at all. Some performance exhaust systems don’t give you an option to connect the sensor. It which case you can unplug the sensor and remove the bulb from the dashboard.

    Emissions Crap,

    Catalytic Converter : Lowers the content of hydrocarbon (HC) and Carbon Monoxide (CO) in the exhaust system, downside is it creates a lot of back pressure in the exhaust system.

    EVAP : Evaporative emissions control absorbs fuel vapours form the fuel tank and releases them into the intake manifold via a charcoal canister on the bulkhead.

    PCV System : Stands for Positive crankcase ventilation. At idle speed the crankcase sucks air in and out via the breather pipe on the rocker cover. This pipe is then connected to the intake pipe before the throttle body . When the engines revs increase and the pressure builds up in the crankcase the pcv valve opens with vents air in from the rocker cover breather and out the breather at the back of the engine beside the oil filter. This pipe goes up through the pcv valve (one way valve) and into the intake manifold. There is a black box bolted to the back of the engine block above the oil filter, this is where the pips joins onto. The box is hollow, its only there to stop oil getting sucked up the pipe into the intake manifold. However it still does at high rpm's leaving you intake manifold dirty inside.

    Miscellaneous Sensors / Information:

    Clutch Sensor : There is a simple switch sensor on the clutch pedal but I am unsure as to what it does exactly.

    That annoying Bong Bong buzzer over 60mph : Inside the dashboard behind the instrument cluster there is a white box with a small round black piezzo buzzer on it. There is a 6 pin yellow cable that plugs into it and a small yellow wire coming out. The big one connects into the ECU, why I don’t know. The small yellow screws onto the back of the speedo. If you disconnect the yellow wire the bong will never bother you again. The box may house the speed limiter. I've never pulled the yellow wire to see. It is possible though that it gets a speed signal from the ECU and tells the ECU when to kick in the rev limiter so the vehicle speed can not rise above 117-120mph.

    ECU Part Numbers,

    1989 D15B JDM CRX 1.5X SOHC ECU (37700-PM4-912) OKI M83C154 (same as an M80C154 but has 16K of ROM on chip) (OKI83C154S.PDF)

    1989 D15B JDM CRX 1.5X SOHC ECU Also had revision (37700-PM4-913).

    1990 and onwards had a revised ECU, a 1991 model has an ECU model (37700-PM4-914). The 1990 onwards ecu's seem to run a lot smoother, the Rev Limiter seems less severe aswell. However they do seen to have less torque low down the rev range.

    1990 D16A6 US CRX 1.6L SOHC ECU (37820-PM6-L09) OKI M80C154

    1989 D16A8/9 EURO CRX 1.6i-16 DOHC ECU (37820-PM7-E031) (643-201115 - 05/04/89)

    holy shiz your wagon looks so NICE!!
  • U R an Ef'en gangsta. All the rides are tight. Slow down so I can catch up!

    The wagon looks sick! I like the R HARTS. Nice Brake upgrade. Do you feel a big difference in stopping? Do you have the stock Master?

    Those Gram Lights are going to look hot on the EVO. Make sure you post picks when you mount them.

  • Gangsta. :shock:
  • sup dude, nice meeting you earlier @ Extreme Autofest

    i'm diggin the wilwood brakes, I think i'm gonna definitely need to do that when I go turbo on my wagon. right now my stock brakes feel like crap, especially in stop n go traffic everyday.

    what was the part# for that? is it the same for all 88-91 civics?

    let me know....

    Nice meeting you at EAF too!

    The wilwoods are great, yeah its the same as the 88-91 civic ones. I am going to change the rotors to the drilled and slotted ones.
