we just did this wap(b16a2) into a '97 cx hatchy. we are using the '97GSR ecu. we are showing codes 22 and 54. please goto this link and read more from the owner. we need some sort of help please people!

if anyone is in the DFW area, PM me.

Jdm engines dont have the crank fluctuating sensor. Ihave a code for this also so i would also like to know how to get rid of the code . you need a usdm vtec solenoid.
i just drill and tap the solenoid on my engine and use the vtec switch off my d16y8

B18C5-EH2

There's no such thing as a JDM B16A2.

come on people. please help me out here. its a jdm b16a2 1/2.<<<<thats what my friend is telling me>>

your problem is probably that the engine is an OBDI engine and you are trying to use an OBDII ecu. If you do this you will throw codes left and right. There are not as many sensors on the OBDI motor as there are on the OBDII so its trying to read sensors that arent there.

i dont know what those codes are but, a gsr intake manifold is dual stage, if your using the stock b16 intake manifold theres a problem...i think the ecu does something special with that, and as posted above, there is no such thing as a jdm b16a2, the second gen b16(OBD1) is called a grey plug, a b16a2 is a 99-00si usdm motor....if the ecu is 97, it should be obd2, if the motor is a 99-00si motor then the ecu would be compatible in terms of obd, but if its a second gen b16 then you need a obd1 ecu...to tell you the truth, the GSR ecu is garbage.

p30 chipped is the answer to your issue.

the code is a cel 54.<<<<cfk>>>crank-pulley fluctuation/fluctuator sensor.

on regards to the ecu being garbage..&lt;&lt;&lt;&lt; a local shop that does all these swaps told me that we needed to use the 97 gsr ecu b'c when we bought the swap, we got an ecu that ew cannot use.

You have a few solutions:

1. Find a 96-98 JDM Integra Type R ECU (will be a "P73" ECU). It should have the 1996-1998 plugs you need for the 1997 Civic, and it doesn't look for the crank fluctuation nor the VTEC pressure switch because the JDM Type R motor has neither. It will also have a higher rev limit and better a/f maps too.

THE JDM P73 ECU IS OBD2 IN PLUGS ONLY!!! IT RUNS AN OBD1 PROGRAM!

2. Find a JDM 1996-1998 P30 ECU from the SiR Civic. Again the same as #1 applies in how it will work. I'm not sure if it reads for the VTEC pressure switch though - I don't think it does, but I have seen OBD1 grey plug JDM B16A motors with a VTEC pressure switch.

3. Get a 1992-1995 SOHC VTEC ECU (it will be a "P28" ECU) and also run an OBD2 OBD1 conversion harness. Both can be purchased from Kenji Plennert at kenji211@tampabay.rr.com - he re-chipped the P28 that runs my B18C5 and it's an awesome program. I also ran one of his conversion harnesses with a JDM P73 (it made the OBD2 plug style ECU PLUG into my 1992 Civic) and his harnesses are awesome.

If you run any USDM ECU you will need to get a VTEC pressure switch from any 1992-up VTEC motor. Even the SOHC D16Z6 ones will work from any 1992-1995 Si/EX. From there hard wire it to the correct pins.

Sorry to say that you won't get that car running right unless you spend some more money on it. You're finding out the hard way that a 99-00 Civic Si B16A2 or the 1996-1997 Del Sol VTEC B16A2 would have been much easier.

If you have emissions testing in your area then converting that 1997 Civic to OBD1 specs might make you fail emissions. Here in GA they plug up an OBD2 scanner to read ECU codes - the re-chipped P28 with harness and JDM P73 ECU will not allow the emissions scanner to communicate with it.

As far as using a GS-R ECU for a B16A, don't. The P72 ECU sucks *** on the B16A and B18C5 motors because of the too-low VTEC point designed for the dual butterfly intake manifolds found on the B18C1.

Lastly don't get pissy when someone tells you that there's no such thing as something that you're talking about in a post. You confuse the rest of us trying to help by calling a JDM B16A a B16A2. If it really was a B16A2 then the trouble shooting procedures would be totally different, so keep this in mind when you ask a tech question.

B18C5-EH2

A few more things:

Are the plugs milky white or grey on this JDM B16A?

Like is the motor pre-OBD like a first-gen or it it the grey plug OBD1 second-gen B16A?

I wish I could tell you some quick fix so you guys could fix it right up tonight, but unfortunately it's going to take more time to locate the right ECU and/or harness and certainly more money too.

I'd just stop messing with it until you get the right electronics.

the only reason i was getting "pissy" was b'c you were being an a$$ about the whole thing. keep in mind that we worked on this thing ruffly 14 hours and everything was discombobulated to me........ i called it an A2 1/2 b'c i was told that was what it was called. and dont be rude in other peoples posts....&lt;&lt;&lt;&lt;
si crx autox&gt;&gt;&gt;&gt;&gt;&gt; thank you though for the tips that you offered. i am going to email them to the friend who the swap is for and who is also a honda-techer. also, i will bring the crappy GSR ecu thing up to the performance shop i talked about earlier, and let them know their other choices.
