car is 2000 civic ex with b18c...it runs fine with the jdm ecu the swap came with but will not start with a 98 (no immobilizer)usdm ecu i have to install and run for emission??? havent looked closely at the car yet but i know it gets fuel??? just wondering if there is a simple answer to this problem that someone knows about??? i dont know if my ckf sensor is wired correctly???? would that be it???

i tryed the ff squad ckf trick but still wouldnt start...now with my jdm ecu i have a code 9 cyp sensor????

 

 

wat kind of usdm ecu u gots ?

 

its probably looking for a crank trigger > some were actually on the crank with a huge cog on the crank gear

 

98 p73

hu???^^^^ explain please??

 

AM bump

 

do you have a conversion harness dude? stupid question maybe but hard to help without all the info and what your doing. 98 and 00 are different pinouts as you already know maybe. CYP is in the dizzy. if your getting that code from the jdm ecu , than trace the 2 cyp wires from the dizzy to the ecu using diagrams. make sure there in the right spots and you have continuity. what year is the jdm ecu and swap?

 

boomslang 0BD2B&gt;0BD2A conversion harness

 

oh and its a 2000 jdm b18c which is an obd2a setup in japan so i have the 98 itr ecu obd2a

 

you sure its a obd2a motor? i believe they changed after 98 jdm or not

correct me if im wrong peoples....

 

dont think so...i think someone sold me a bad ecu

so i got it to run holding down the gas...wont idle at all...and i got 3 codes
9 cyp
41 O-2 Sensor Heater
65 Secondary O-2 Sensor Circuit
BUT my buddys 98 integra with an odb1 b16 wont idle either and he gets a

ckf and vtec code

help me please

 

instead of using the p73 try a p72 gsr ecu...and see wat happens...

 

Is it a USDM ITR ECU? When i ran an ITR ECU in my 99 civic, i had to move the fuel pump relay wire over to the next pin on the ecu plug, its something like A14 to A15, don't remember for sure though...

 

a 2000 ecu is not obd2a , regardless if its JDM. JDM ecu's utilize less sensors than us though , like only 1 o2 sensor , no CKF , no vtec pressure switch. couple differences. maybe theres something wrong with your conversion harness. just run the jdm ecu man, why wouldnt you. its an obd2 ecu that runs like obd1.

did you have a coversion harness?

 

im putting this ecu in to pass emission in CT

 

if all you need it for is to pass emissions , than find someone with the same year car as yours , but GSR , and borrow thier ecu for an hour dude. than when its done , throw the jdm ecu back in it.
