JDM D16A What ecu to use?
Hello everyone, I'm new to Honda-Tech. I drive a 1996 Honda Civic EX. It had a D16Y8 5-speed with about 280XXX miles before she decided to go. I recently picked up a JDM D16A from a local guy very cheap. My problem with this swap is that I'm unsure of what ecu to use or if my stock Y8 ecu will even work. All I know about the motor is that it has P2J-3 stamped on the head, says 01 on the top right side and 98 on the bottom left side with 3 dots underneath. I have the D16A just sitting in the garage waiting to be put in. I have searched this topic to the point of getting migraines and have gotten nowhere, that's when I decided I'll register on Honda-Tech and let the gods shed some light. Any help or valuable input would be greatly appreciated. This is a budget build and would like to go the cheapest and simpliest route. Thank you everyone!

Single vtec solenoid?
It's not OBD1 btw. '98 is the year of the head. Also not the dipstick, it's plastic and on the side. OBD1 comes up betwee cylinders 2 and 3 on the front of the engine. That cam pulley is OBD1 though. You'll probably have to swap it for a Yy/Y8 pulley to get it to run right.
Yes you can run the Y8 ECU, but you'll need to bypass the CKF sensor and swap out the oil pump for a USDM Y7/Y8 oil pump

Re: JDM D16A What ecu to use?
As for the ECU, you could just use a stock P28 really. The engine is nearly identical to a D16Z6. If you go that route keep the timing pulley it has now.

You would have to be absolutely high to run an oil pump off an engine that blew up. Even if it didn't spin a bearing I probably wouldn't use it. Either a new pump or just do the CKF trick like most people do.

The OBD1 P28s are OBD1. There is an OBD2 version ('96 - '97 Del Sol Si), but they're rare as hell and you're unlikely to run across one.

Re: JDM D16A What ecu to use?
Edit: The reason I ask is I believe the OBD1 ECU does not look for the secondary O2 sensor nor the CFK. I have also read that the JDM D16A does not have the CFK. That being said, I believe I wouldn't have to mess with it at all. Someone correct me if I'm wrong. Thanks!

Re: JDM D16A What ecu to use?
Yeah if you're running an OBD1 ECU there's no need to do the CKF trick as the ECU wont look for a CKF sensor. There's really no need to chip a P28 to run what is essentially the engine it was designed for though.

Re: JDM D16A What ecu to use?
Edit: Is the JDM Dizzy and IM useable or would I have to swap my Y8 Dizzy and IM over? Also the IACV is a 2 wire on both motors, but on the Y8 it looks to be a female end while the D16 looks to have a male end. Anyone forsee any problems?

The IACV should be the same and have the same plug actually.

Re: JDM D16A What ecu to use?
You can always get a chipped P28 and cut the jumper wire for J1 and run it stock until you boost it. Or just get a stock P28 and chip it later.
The distributor is the same. IM will work, it looks like an OBD1 IM actually.
The IACV should be the same and do the same plug actually.

When J1 is connected the ECU reads off the aftermarket chip. When it's not connected it reads off the stock program.

Re: JDM D16A What ecu to use?
Nope, OBD1 and OBD2 distributors are electrically the same. The only difference between them is the plug(s) where it connects to the engine wiring harness. OBD0 is different though.

Re: JDM D16A What ecu to use?
Okay guys, so I have one last question about this swap. I plan to use a P28 ECU with my JDM D16A. Should I get a virgin P28 or a chipped P28? Does it matter? Is there anything I should be looking for in a chipped ECU? What do you guys recommend? Thank you.

Re: JDM D16A What ecu to use?
As many times as I ******* need to till I get my damn answer you *****. You still haven't answered my question but yet insist on being on being a dick. So there really would be no difference between running a virgin P28 and a chipped P28?
