So I've been hunting down and been searching for the last couple of years for information in regards to obtaining a BAR certification sticker.

I'm planning to swap over my 00 GSR motor from my sedan to my 96-98 obd2a ek.

I keep reading now how you can't BAR a gsr motor because it never came in that model of car anywhere in the world. As with some people saying that only applies to JDM motors.

For example,

I.E.

INTEGRA GSR WITH B18C1 CAN INSTALL A JDM B18C IN TO IT AS LONG AS IT HAS THE PROPER EMISSION EQUIPMENT.

CIVIC WITH D15B7 CAN INSTALL A JDM D15B
DEL SOL WITH B16A3 CAN INSTALL A B16A
AND SO ON

===

THEY ARE NOT SAYING JDM MOTORS ARE NO LONGER TOTALLY ALLOWED, THEY ARE JUST NOT ALLOWED IN VEH. THAT WERE NOT ALREADY EQUIPED WITH IS USDM SISTER MOTOR.

IN THE END YOU CAN STILL DO WHATEVER MOTOR SWAP YOU WANT IN YOUR VEH. AS LONG AS YOU USE THE OLD LAWS ALREADY STATED AND THE NEW AS IT CAN ONLY BE USDM MOTOR IF THE VEH. WAS NOT ALREADY EQUIPED WITH THAT MOTOR.

EX.
1990 CIVIC WITH JDM B16A NO NO NO!!!
1990 CIVIC WITH USDM B16A3 OR B16A2 OR B18C5 OR B18C1 BLAH YES YES YES!!!

can anybody confirm this?
Also i've read through this and it doesn't state anywhere that you can't swap a different engine it just says all smog equipment needs to be installed.

Some other questions I have are

1. 00 GSR swap in EK - can i use a obd2b jumper harness to obd2a or would have have to completely swap over the obd2b engine harness, cabin harness, and floor harness. I've read a bunch of mixed yes you can use a jumper harness and no you cannot. Please if anybody has any insight would greatly appreciate it.

2. CODE 91 - I've read KATMANS FFTECH article about how to bypass or fool the ecu with

Fool the ecu
We fool the ECU by providing a similar voltage that the FTP would normally send -- this happens to be around 2.5v. You need to acquire a 10k linear potentiometer: Radio Shack Part Number 271-1715.
The outter 2 pins are going to be +5v reference and ground (does not matter which), while the center pin will be your output feeding back to the ECU pinout.

(Before you hook up the pot's center pin to the ECU, use a multimeter to adjust the output to 2.5v.)

There was a few people saying that when the gas tank builds up pressure and the valve closes that the ecu will notice the same amount of voltage being sent to it and still will throw the code for 91.

Also the second alternative was to swap the gas tank out. I was leaning more towards this route, but my question for that is



that FTP sensor has a two wire plug, i was wondering
do i wire up light green wire from the sensor on the gas tank to Connector D slot number #15 on an obd2a harness considering that im allowed to use a jumper harness for BAR. If not allowed the jumper, then A29 on an obd2b harness.



EDIT: 2-27-13 i just picked up an si gas tank with the ftp and bypass sensor, my question now is the light green wire for the ftp is there and also the blue wire for the bypass but what are the extra 3 wire for?


Also i will be using the CAT off my 00 gsr in the ek as far as the piping i'm assuming that i would go to the muffler shop and get stock specs for 2" bpipe with a stock ek exhaust?

I know i need to bypass the IMM on the ecu.

Now sorry for the clutter in this post, but ANY OTHER helpful information is welcome in regards to my obtaining a bar sticker would be much appreciated.

A motor being available in the target chassis doesn't matter. What matters is that the "classification" of the motor matches the target chassis. The B18C1 is a passenger car motor, and your EJ6/8 is also a passenger car, so that doesn't matter to you.

The motor is newer than the chassis, so that part of BAR code doesn't affect you either.

The primary problem I see you running into is BARing an OBD2B motor in an OBD2A chassis. Before you go worrying about the fuel tank, I would find an OBD2A GSR ECU, swap the motor, plug in the replacement ECU, and see if it throws any CELs. You shouldn't need to swap tanks, since the general system is the same. That doesn't really become a concern until you start looking at K swaps with their returnless system.

I wouldn't pass bar with the obd2a ecu considering the engine is obd2b so i would have to run an obd2b ecu from my understanding. As far as the CEL's go i believe if everything is swapped properly then the only issues i would have is the evap bypass, fuel tank pressure sensor which is located on the gas tank and also i would need the IMMO removed.

Also can anybody help me out if this is right, the plug i have in the picture above of the connection wires for the evap bypass and the ftp sensor,

just wondering if this wiring is correct

OBD2A harness
sensor | ecu pinout | color of wires
PTANK - D15 - LT GRN
SG2 - D11 - GRN/BLK
VCC2 - D10 - YEL/BLK
2WBS EVAP BYPASS - A28 - BLU
PG1 GROUND - A10 - BLACK

Uh, you can't run an OBD2B ECU on an OBD2A harness without an adapter, and I believe (although I could be wrong) those adapters make your diag port useless, which is an instant fail. You can, however, make an OBD2A harness work on an OBD2B motor with only minor modifications. Unless you plan on ripping the entire wiring harness out of the donor car, as welll?

I know you can't run obd2b ecu on obd2a harness. i would have to use a jumper harness for it to work. That's the reason why in the original post i was asking to see if its possible to pass the BAR testing with a jumper harness because i've read that people have and yet still some people say no so i was looking for a straight answer. Also if i can't use the harness then i will most likely convert the cabin harness floor harness and engine harness to obd2b from a 99-00 civic.

but to help clear things up ill be running obd2a harness with obd2b ecu and jumper harness, immo removed, evap bypass, ftp sensor hooked up .

Evap bypass may cause you to fail. When you start the car the system looks for minor differences in the voltage sent to the computer, if you are constantly supplying one voltage it will not bring the OBD2 system monitor online. If CA requires all systems to be online it will fail. They solution is just swap everything over from the SI gas tank, I have heard you can do this without replacing the whole tank.

"Uh, you can't run an OBD2B ECU on an OBD2A harness without an adapter, and I believe (although I could be wrong) those adapters make your diag port useless"

Not true I ran an SI ecu on my 96 and could read codes afterwards.



You know you can always call the BAR place and ask them some questions.

So, i shouldn't even bother with dropping the gas tank? I do currently have the sensor on hand so i can just mount it up?

search, I thought I saw you do not have to

When I passed my JDM GSR, the ref asked me, "what year do you claim this motor to be?" I said, 98 GSR motor, sir. The motor was actually a 96, and my car is a 97. Yes, he checked the year stamp on the head. I'm not too sure how I got away lol.

So why not try this route? It's worth a shot. Just tell the ref it's from a 98, get obd2a everything, and pass.

where did you ref and how long ago was that? maybe i can try that haha

iTrader: (1)

also did you swap into an ek?

B(eighteen)C

Why don't you just run a obd2a gsr ecu....?

Hook up the evap sensor and the block it off so the ECM thinks there's no leak...?

ekx4

iTrader: (1)

^ what do you mean by block it off? the evap bypass valve?

because the engine year is 00 and the ecu needs to be obd2b IF the state ref (bar) checks, but zerovandez said he got away with running obd2a i would run obd2a if i can get away with it at the bar testing, something i might do, worst case scenario i will have to run obd2b.
