    My total frankenstein..just a surging idle.

    Okay, so I'm running a OBD0 B16a, converted to OBD1, with a custom wiring harness, in an all custom 99 Civic sedan chassis. The ONLY problems I'm having are codes for O2 and knock. However, even after tuning the ignition timing, the idle now surges just slightly between 1k and 1200. Now, I...

    Troubleshooting My Swap

    Yes, it IS in fact a JDM ecu. I didn't really pay attention. But still, I dont' believe there's a knock sensor on the motor and I've seen footage of the CRX from the guy I bought it from. To the best of my knowledge, OBD0 didn't come equipped with knock sensors and there is not one on my block.

    TX Want to trade VIRGIN USDM OBD1 P30 ECU

    I'm sorry it's JDM I read the numbers wrong.

    This IS an OBD1 ecu correct? Or is it a Civic SI?

    TX Want to trade VIRGIN USDM OBD1 P30 ECU

    Would like to trade my p30 (USDM from Del Sol, untouched) for a chipped and socketed p06 or p28, that already has a chip for an OBD1 B16 with knock and o2 deleted. I must receive yours first as it is my only car then will ship mine.

    Troubleshooting My Swap

    The ecu is fine, but you're right I should probably just trade for a chipped and socketed p28 with an eprom b16a obd1 w/o knock and o2 and I'd be better off.

    Troubleshooting My Swap

    Before I tuned the ignition timing the timing belt was jumping all around but now it stays still and looks right maybe I should check the tensioner tomorrow.

    Troubleshooting My Swap

    But I still gotta figure out the back pressure issue.

    Troubleshooting My Swap

    I would like to salvage the p28 but I really jacked it up pulling out the old chip it's destroyed. I'm totally lost as to the o2 issue I'm pretty sure it's running just fine but I can't clear the code. And I only use 91 octane. It ran way better with o2 deleted on the p72 map though.

    Troubleshooting My Swap

    Okay so, I think I've figured out why this is giving me a small headache. The b16a is OBDO, converted to OBD1 with injectors, etc., and we're running it on OBDII wiring if I'm not mistaken with a xenocron conversion harness. I replaced the o2 sensor and it produced very little results and still...

    Troubleshooting My Swap

    It's showing 23 and 41, knock and heated oxygen. The ecu is from a Del Sol VTEC so I'm pretty sure it's OBD1 and only needs one sensor. BUT, I also forgot to mention that the sensor was NOT spliced it was plug n play brand new. Also forgot to mention that we were running very rich for a little...

    CEL in b16a swap..question?

    By the way, for some reason, when I floor it it doesn't want to really accelerate past 100 mph?

    Troubleshooting My Swap

    Okay, so I'm running an OBD1 b16a in my 99 sedan. It's throwing code 41 heated oxygen sensor. Now, it's a JDM b16a but I'm running a USDM P30 ecu from a del sol. Could this be why and if so, how do I fix it? Also, did the USDM b16a come with a knock sensor that it's trying to read but isn't in...

    CEL in b16a swap..question?

    So, I'm running an OBD1 b16a swap in my 99 sedan. The problem is I have a check engine light on throwing code 41: heated oxygen sensor. Now, the ecu I'm running came from a del sol vtec and it's not JDM so..could that be why I'm throwing this code and if so, how do I fix it? Reason I ask is...

    98 hx coupe obd1 b16 issue

    Well, it dawned on us that we were using y7 injectors so we grabbed some b20z4 injectors from jjunkyard 97 crv and it revs now but we can't drive it because injector number 3 is squirting fuel, just gotta replace orings. It's my friend's car so I'm not sure if it's still throwing codes or not...

    92 accord swap, jdm f22b. Done research, in planning.

    So..I'm planning on swapping my brother's 92 accord DX and I've done research on these forums and found some things that need answers. Motor is leaking oil like crazy from cam seal, and I found the swap I want to put in it. I wasn't able to find another f22a1 however, the closest I can find is...
