Whats up... Im working on my 99 ek gsr jdm swap OBD2a and im picking up a si harness tomorrow and ive bough a obd2b to obd2a jumper off ebay. I just want to know if its plug and play and if i have to switch any pins on the harness??? LMK Thanks

 

-Wire up IAB's (if you are using them)
-IAT won't plug up but you can put your current IAT into your new intake arm
-wire up secondary O2 to ECU
-are you in a state with emissions that plug to the ECU? the JDM ECU won't read properly and will fail emissions
-ckf will be left hanging by the crank as the JDM ECU does look for it and the JDM engine won't have it

 

I suggest just going obd1 with a p28 that way u don't have to hook up cks, ks and such. otherwise everything should plug in. my gsr had a iat sensor in the manifold.

Yeah but the 99-00 Si IAT doesn't use the same IAT as the B18. It depends on your state emissions whether you can do OBD1 and pass.

 

Hey i was wondering if you know how i can get my 99 EK JDM GSR to pass an NY inspection it running a engine code but i can't read it since it a jap ecu and when i plug my b16 ecu in it comes up with a ECT code P0118 and i clear it and it comes right back?????
