i have a 96 civic with a 2001 jdm gsr..now my prob is the check eng light is on cause the immobilizer from the gsr was removed to make the car run. can a usdm ecu plug into the harness without cooking it. some ppl are saying that the iab circuits are reversed and i will burn up the usdm ecu. i need my car to pass emissions and it wont obviously because the check eng light is on. any help ?????

Try pulling the CEL code first to see exactly what it's throwing.

I didn't know the JDM motors had immobilizers built into them...?

if it helps, i ran a stock USDM P28 ECU on my '94 JDM GSR in order to pass smog. it passed with flying colors but i don't want to recommend it for you *disclaimer*

shoklid

the code comes up as ecm failure..

from some searching on Google, it comes to the general consensus that the ECM failure code means you need a new ECU...ouch dood.

Your best bet is to find a OBD2A ecu for a GSR. I ran a OBD2A ecu w/ a jumper harness (cause 99 is OBD2B) in a 99 Civic EX on a B18C JDM GSR motor. I had all the smog equipment for my 99 EX hooked up properly and it worked fine and allowed me to pass smog via the plug. I don't know about your state, but here in AZ, they hook you up to the machine and if you don't throw codes, you pass.

They don't, the '00 - '01 USDM integras have an immobilizer built into the ECU rendering them useless outside of their original vehicle, the immobilizer can be removed, but it leaves you with a solid CEL, the CEL IIRC comes back as EXM failure, but it will otherwise function perfectly fine. You can also send the ECU to katman and have him remove the immobilizer and install a dummy unit that eliminates the CEL.

shoklid

is katman a web site i can go to ? i ordered a usdm ecu an hour ago to see what it will do um and yes PA does the plug in emissions test no codes you pass....i hate emissions im about to go back to 95 and older, obd1 i wouldnt have this prob.

shoklid

oh and i dont have a usdm gsr swap its def jdm and the car it came from had a chip that i dnt have making the car not start. so something WAS removed causing the cell to fail on comp diagnostics

94EG8

Katman is actually a honda-tech user, you can PM him for more info. Again though, no JDM P72 GS-R/SiR-G ECU had an immobilizer. I should mention though. I hadn't noticed this earlier, but you have a '96 civic, any USDM OBD2A '96 - '99 P72 GS-R ECU will work fine, these do not have an immobilizer, only the '00 - '01 USDM units have an immobilizer.

shoklid

urgh then i wonder what this dude is saying he removed it for if it wasnt there to begin with

Redbone

just get an USDM obd2a gsr ecu and pug it right in, MAKE SURE IT ISNT AN AUTO TRANS ECU!!!

shoklid

yea i bought one 3 days ago i just got the usdm p72 in yesterday and no cells are coming up so everything is working fine and btw whoever said i needed a jumper harness u are 100% wrong i took out the harness for the jdm ecu and it plugged the usdm ecu right in the stock civic harness. job took a whole 5 seconds and works fine so thanks for all the good poss feedback everyone

shoklid

ok well check eng light came back on. so usdm ecu does not work

nub

The cel comming on doesn't indicate the ecu doesn't work. You need to pull the code. You may not have a set of sensors with similar plugs connected correct or it may be a bad sensor.

Apparently, reading > you. I never said *YOU* needed a jumper harness. I said:

I have a 99 which is OBD2B not OBD2A which is what your car is. *I* needed a jumper harness. No where in my post did I say *YOU* needed a jumper harness. All I said was that you needed the ECU.

Like the poster above me said, you need to pull the code to see what sensor you are missing then we can help you out further. My guess is that you are missing the crank fluctuation sensor which is what that OBD2A ecu is looking for. You need to do this:

oh i musta miss read what u wrote my fault. im just getting frustrated and tired of doin all this stuff. it seems endless and im tired of getting pulled over loml my apologies

Get the CEL flashed. Autozone does it for free. Maybe you have some other issue.

kulo

can u run a p28 on a b18c1
or will it damage the motor?

or keep it below 3k rpm and drive it it to get it tuned?

94EG8

Check and see what codes are being thrown, note that it will be throwing codes for the CKF sensor as the JDM engines don't have them, along with the fuel tank pressure sensor, and possibly the vtec pressure switch unless someone swapped on a USDM vtec solenoid, or an OBD1 JDM version.

shoklid

the onlycode that came up was the cks

shoklid

actually im wrong its the knock sensor that came up? does that mean its bad of i dont have it ? not the cks

310HPS2k

I have a JDM GSR ECU if you are interested.

shoklid

i have a jdm ecu that works fine exc it blows a cell.. the usdm blows a knock sensor im just not goin the get my car inspected **** it

Are you sure it's not a cel for the cfk. The jdm motors don't have the cranks sensor and the usdm ecu will be looking for that. technet.ff-squad.com would be the "katman" site There is info regarding your issue there.

shoklid

yea i got the cell read and it comes up knock sensor and the usdm ecu wont let me rev up past 2500rpm "runs like ****" and stalls out but thats the only code that comes up. the jdm ecu runs fine, the way it should run. i cant even drive one mile with the other ecu it ran fine till about 60 mile on the usdm ecu then tripped the cell now it runs like poop
