well you can use the 99 LS ecu, but you'll need to get an OBD2b to OBD2a jumper harness adapter (which i sell
) in order to plug n' play to the ecu. Either that or convert to OBD1 and run an OBD1 LS ecu.
You won't want to use the 00-01 integra LS ecu because of the immobilizer situation. Although I do have a way to bypass the immobilizer and you won't have a constant CEL light. Actually this would probably be the cheapest route. Hit me up if you're interested...

Re: (Katman)
Hey Katman, I am in the middle of swapping a JDM OBD1 B16 SiR II in my 97 DX, I thought that all D series injectors were 240cc but now I am not sure. I didnt want to convert my OBD2 injector plugs to OBD1 so is it ok to use my DX injectors or should I just convert them? If so, what route should I take to convert them, thanks.

Re: * * OBD1 B-series engine into OBD2a/OBD2b civic/integra * * (Katman)
I have a 2000 honda civic DX. I pulled the d16 and replaced it with a 98 b18c5 out of a type r integra. im using the engine harness from a 99 civic si. my si harness only has 8 wires my dizzy has 9. im using a 99 si ecu. car starts in limp mode. but if you rev it up a lil turn the key to off and back on then you can trick it and it will rev all the way to 9000 rpm. but then the car wont idle it shuts down if you dont keep the idle above 1500 rpm. i tried to swap a 99 si dizzy on the motor and it wouldnt even attempt to start. Now i have a P06 ecu chipped with the Hondata S300. Unfortunately you cant trick this ecu with the key trick. so i can rev to 3800 and thats it. Does anyone know how to fix this.Will trying a 99 si dizzy on this ecu work? I have a new one on the way just waiting on it to get here. I need it to run right so i can get it on the dyno and get it tuned. Im only running 5psi of boost right now cause im afraid to go any higher. Im still using the 99 si ecu so i can trick it and get it to rev.Any help would be greatly appreciated. Thank you.

hey katman, new to this whole scene, got a 96 civic ex that had the d16y8 in it. i just bought a b16a2 out of a 99 si. now from what i read in order to use that 99 ecu i have to get the jumper harness, a to b, right? which by the wya you sell right? or can i use a obd1 ecu? sorry for the noob questions, btw grat thread

Welcome...
That is correct, you would need an OBD2a->OBD2b jumper harness to run the 99 Si ecu or if you wanted to convert to OBD1 you'd need an OBD2a->OBD1 jumper harness & OBD1 ecu such as a reprogrammed P28.
OBD1 allows for reprogramming whereas the Si ecu does not.

Re: (Katman)
so do u have htose jumper harness.i have a p28 ecu out of my old civic and i also know where i could get a p72 if i were to go obd1. would the p72 be the better option?

Most of the D & B-series injectors are 240cc. Your OBD2 DX injectors are 240cc if memory serves me right, so you can use those with your B16 swap. Btw, you can make OBD1 injectors fit into an OBD2 plug by pulling out the blue insert as seen here:

I believe if you have an Si of HF model, you're ok, but the lower models (DX/STD) need to have the spindles swapped out for that of an Si or HF model spindle.

Yes - IF using an Auto harness in a 5speed chassis.
Reusing an Auto harness in an auto chassis converted to 5-speed has been reported to work.

hmm...if you truly have an Si engine harness and Si ecu, you shouldn't be having these issues. The car should start up fine, if everything is installed correctly when using the Si distributor (ground wires are grounded, plugs are fully clipped in, etc). I'm going to guess that your engine harness isn't Si spec or somthing along those lines.
Can you put your Si ecu back in along with the Si distributor, get the CEL to come back on and and find out what CEL codes you're getting are?
here's a how-to on checking the CEL light codes:

Re: (LA_HONDAS)
I have a 99 civic ex and just put in a LS swap (reused my engine harness). The dizzy plug is different. I read this post and it turned out that I have to convert it back to the older style "big plug." Is there a write up of how to do this?

it would be the same overal installation procedures as a VTEC engine swap minus the VTEC and knock sensor wiring.

Re: * * OBD1 B-series engine into OBD2a/OBD2b civic/integra * * (Katman)
hi katman
i have a problem. my wiring harness is an OBD2b harness out of an 99-00 Honda civic. Everything is plugging up execpt for the dizzy. the harness is an 8 pin while the dizzy is an 10 pin. Do you have any idea how to rewire it so i can use my 8 pin harness to the 10 pin dizzy
Thanks
Ian

when you swap over to the bigger OBD2a dizzy plug, just color match the wires to their respective pin locations.
You can also use this diagram as reference:

welcome..
You'll have to reuse your 00 engine harness on the 96-97 (OBD2a) EX D16Y8 engine. If the 96-97 Y8 engine comes with an engine harness, you will have to swap the dizzy plug over to your 00 harness. 99-00 civics use a smaller dizzy plug.
To use the OBD2a EX ecu, you'll need to purchase an OBD2b-OBD2a ecu jumper harness adapter (which i sell
).
