Where is a realiable place to get a p30 ECU and the conversion harness? Guys thanx a lot for helping me in this time of hardship, I really do appreciate everything you guys do to help and to teach me. Mr.Fatbooty, thanx for putting up with me for the past few days, im sure you've got better things to do. Thanx all

 

I would suggest going to the OBDI ecu, but adding the CKF sensor is also possible and fairly easy.


ECU: Super easy... like... braindead monkey easy. But expensive.

CKF sensor: Cheap for parts, but time consuming labor wise.





I would do the ECU in the blink of an eye. In addition to resolving the CKF issue, the car will run better with proper fueling for its camshafts, intake manifold, and displacement.

Right now your car is most likely running at about 8/10ths because the GSR ECU is programmed to run the dual butterfly intake manifold.


WARNING: I do not know the emissions rules in your area. It is entirely possible that the car will not pass emissions with an OBDI ECU. In addition, it's possible that the car will not pass emissions at all because it is equipped with an engine older than the year of the car's production.

 

Josh, you used to live in mesa, do you think that I would be able to pass emissions with an older motor and OBD-1 ECU in my car?

BTW: I live in Mesa, Arizona 85208, if anyone knows the laws around here.

 

If the OBD-II versions of the B16 do not have a CKF sensor then you can use an OBD-II B16 ECU and it should work fine. However I don't know if the CKF sensor was added when OBD-II was added or not.

 

I'm pretty sure a '99+ Si uses a CKF. I haven't looked at a B16A2 oil pump but I'd put even money on it being basically the same part as the '96+ B18C1's, with the sensor.

Do you remember the tech asking or looking at the ECU? Actually, the blub was ripped from the check engine light and he knew there was a code. Most likely he hooked a computer up to your diagnostic port and read the codes that way. If you put an OBD I ECU, the diagnostic port may not function anymore (I think that was an OBD II addon). Do you know any of the tech's from the inspection place or have a friend who does? Sometimes you can work out a deal where they only go based on the sniffer test or you can just get them put a sticker on. I don't have emissions testing around here so when I get inspected, they just switch the stickers for me.

 

You are in the same situation as I am. I have a obd1 b18c1 in my obd2 car, and the only code it throws running an obd2 p72 is 1137. I'm looking for some more info on adding the CKF sensor to a obd1 motor. Do you just need to change the oil pump to an obd2 version, or is there more to it that that? I always run a obd1 p72 ecu, I just need to run an obd2 system for emissions. CiViC2nR86: I have been looking at all the options for passing an obd1 motor in an obd2 car, and this looks like the only option is adding a CKF, unless you have a hook-up at the emissions place. You should already have all the rest of the obd2 emissions stuff because you car was originally obd2 anyway. You can't run an obd1 ecu becuase when they plug it in to the diagnostic port, it will not read. if you find another way to pass please let me know. BTW: great info form everyone elce, some of you guys really know your stuff.

 

What about that little button behind sort of under my sterring wheel behind that box? I had to push that once to reset my check engine light because the mechanic forgot to after I left. What does that do? Just resesets your check engine light time?

 

no you had to do that to reset your maitnance required light mrl and cel are two totally different things

 

Since the tech gave the actual OBD-II code rather than a CEL code I'm thinking that he scanned the diagnostic port as part of the test, and the diagnostic port is indeed a feature exclusive to OBD-II cars.

It also seems to be the consensus that the CKF sensor was added for some reason when OBD-II was introduced.

So...since you need to run an OBD-II ECU to keep the diagnostic port functioning, and all of the OBD-II ECUs out there will want to have a CKF sensor plugged into them, it looks like your only solution for passing emissions will be to get a CKF sensor added to your car somehow.

 

Do you only need to swap to an obd2 oil pump to get the CKF working, or is there other parts that are needed? Swapping oil pumps is not that big of a deal and should be an easy solution to both of our obd woes.
