Here's the skinny i have a 97 EK with a JDM B18C swap it has a P72 OBD II ecu that i cant get the OBD scanner to recognize is this a common problem with JDM ECU's or can it be a problem with my ecu. any help would be appreciated.

 

The jdm b18c is the usdm b18c5.

Are you sure it's a gsr motor? If it's jdm and is badged b18c, it's likely the type-r.

 

Yes the JDM B18C is just a GSR motor the Type R is a B18C5....

 

nahh. there are JDM GSR that are also stamped B18C just like the JDM-R and i dont know the answer to your question

USDM-B18C5(type R),B18C1(GSR).
JDM-B18C (GSR or TYPE R)

 

None the less my question still remains is there a tendancy for JDM ECU's to not scan via the OBD II port or is my ECU having issues.

 

obd scanner as in to check your ecu codes?

 

Yes i have tried the paper clip in the self test port as well and instead of a series of flashes i get a solid MIL light. currently i have no check engine but for smog i need my ecu to communicate with the obd II scanner.

 

JDM ECUs will not connect to USDM scanners.
You need a USDM ECU to pass emissions.

 

What about the fault codes from the lack of 2 sensors. is there a way to bypass them?

 

which fault codes?

54? (CKF) <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">I posted were only for obd2a, if you are obd2b it will be different. From what I can remember from that old post for obd2a you take the ckf(the crank sensor you dont have) which is pins 1 and 11(11 should be directly below 1) and cut them a few inches from the ecu, then take the ecu side and tap c1 into c4 but make sure the original c4 is still hooked up. Then tap c11 into c14(c14 is directly below c4) leaving c14 hooked up as well. Now the wires for c4 and c14 should go into pins both c1, c4 and c11,c14 respectively. The wires for c1 and c11 on the harness side stay unhooked as they went to the sensor that is no longer there anyways.</TD></TR></TABLE>
found after searching for CKF bypass.

which other CEL would you have?

Found that out trying to get a 00 Si through with a CTR ecu.
