Help!!!!!!! b18c swap questions

[2point1]

If its an obd1 p72 then it doesn't look for a knock sensor. I had a 97 spec JDM ITR swap in my ej1 running on a stock obd1 p72 and it ran mint no problems at all.

i had an obd-1 us p72 ecu in my eg with a b-swap and it in fact did throw a code for knock when not hooked up......

Thats wierd because the only CEL I had was for an o2 sensor because I was running one piece ceramic headers..

use the harness thats in the car on the motor. If you have a OBD2 dizzy, just de pin the dist. and put a OBD1 plug on the end. or the other way around, doesnt matter.

Use ur b18a alt so it plugs rite in.You might have to wire ur knock. But its a single wire, so its easy.

Use your b18a injectors.

and your throttle body will work just fine.

Between the 2 motors you have, you shouldnt spend another dollar on anything but a computer.

doesnt have to be hacked, but do it either way. It doesnt matter.

the pins are different between obd-1 and obd-2,so how you gonna hook them up with out hacking them up...

so i was talking to someone and they were saying that because my car is a ex that it should be already wired to the shock tower for vtec??? I was told the only thing i would have to wire is the knock sensor.
does this all make sense to you??
because my ecu is a obd1 jdm p72 does it have the knock sensor programmed?

harness will work if USDM. no need to wire knock sensor if your using obd1 ECU... no wiring plug and play

[ManTyme]

use a p28 or USDM obd1 p72

Thanx for ur input nd I'm serious I don't think u need to wire a knock just tho ur swap in keep everything Obd2 use ur jdm ecu nd if it throws a code just check it nd if its cause of the knock then wire it in most ppl just don't use there is a write up on Honda tech to eliminate it


Nd here is another person that knows

harness will work if USDM. no need to wire knock sensor if your using obd1 ECU... no wiring plug and play
