You're probably not seeing the issue here but I'm going to wait and see what OP has planned and assist him as best I can.

98civdx

was there ever even a auto with Vtec?

tony_2018

jdm land, obd2 versions and obd1 versions.

tony_2018

You know whats fucked, I bookmarked a honda site that sells new/used jdm parts that lists them by make/model/part #'s, and now I can't find it.

I am seeing the issue, i was just letting him know that if needed rywire can help with a harness if needed.

tony_2018

There's a sensor he won't be able to utilize, the linear solenoid. Thats the issue. There's no obd1 solution for that. I'm hoping he was able to find an obd2 ecu and what ecu he used. The obd1 solution is to find a transmission with the kick down cable

Hey sorry every one thanks for the info I haven't finish the car yet had to see a family member at the hospital but I am back now. I saw the comment on the crv harness and decided to see if that will work on the civic. I am trying to get it to we're I don't have to mod anything so tomorrow I am going to pick up the harness and instal it and add the intake and finish by this Sunday and post a YouTube vid

tony_2018

But what ecu will you be running?

tony_2018

You'll have to wire up your tach directly to the distributor, 99-00 civics get there tach from the obd2b ecu, since you're using an obd2a it can't find it. Also are you using a conversion harness, you'll need that.

New tech

There are several ecu I'll be testing out on this swap like the p2t, ex I think it's p2e and the converted adapter for a 2001 lx auto ecu

New_tech, the problem you're going to run into is this: The TCU is (usually) integrated into the ECU. You'll need an ECU that matches both the transmission and the engine, or you'll need to find a separated ECU/TCU combination that'll work, as well as the wiring harness to run the separated control units. Exactly what did the transmission come out of? Yes, I know it's a 00-01 Integra, but is it an LS, or the uber-rare GSR auto that I've heard whispers of?

The issue you're going to run into is in the electronics between the engine and transmission. I've seen plenty of people pipe-dream what you're doing. I've tried to help a few gather information. I've seen two people claim to have pulled it off, but exactly zero people who have proven it with something as simple as a video. I was serious when I said this would probably be the most impressive thing I've seen, and I want to see it happen. Thread-jacks from someone else who clearly hasn't even begun to do any research are not going to be conducive to that.

Hello, Hope someone can help me out here. I'm doing a JDM B16A swap with a S4XA automatic Trans and a P2T-J91 ECU into a 2000 Honda Civic EX. I got everything working besides the fuel pump and the rpm's aren't working. The main thing I wanna fix is the fuel pump. I hear the main relay for the fuel pump click on but the fuel pump doesn't prime or turn on. I ran a direct wire to it and it works and the car starts. As for the rmp's the wire harness on the driver side strut tower that goes into the car has only one plug the the engine wire harness has two plugs. The bigger plug plugs right in but the smaller one has nowhere to plug into. I'm also looking for a kick down cable. Can anyone help me out PLZ?

This project is for the wife.

Interesting....I'll do what I can.

tony_2018

You can tap into that blue single wire thats sitting right there on your driver side shock tower. As for the fuel pump, I think I know your issue and the easy way is to get the obd2b to obd2a conversion harness. It should automatically help get you goin.

edit: show me your ecu plugs.

New tech

On the transmission code # is SKWA from a 2000-01 integra when u look at the lx civic and the integra auto trans they are exactly the same they have the same amount of plugs for the sensors and solenoids . I could still use the 99 ex harness but I would have to mod the plugs for(IAVC and crank sensor 3 wire 2 wire plug)and also the distributer. I want to see if I could use the CRV's wiring harness to connect to all the plugs on the engine except I will have to add the nock sensor and vtec also the crv's also have this trans with the same plugs trans code # is SKRA in which the engine harness I could use. So my question is? Can u run a p2p lx, p2e ex ECU on this engine if the the sensors are the same on the trans using the crv harness since I don't have to mod the harness?

I don't have a picture right now of the ecu plugs. I'll have one tomorrow. As for the harness... I have the JDM b16a engine wiring harness for a automatic that was modified for left hand drive.

Not really no. A D series ECU is not going to properly run a B series motor, and neither of those will properly read the transmission. Your best bet would be to either source a SiR-G automatic ECU (good luck on that), or adapt your harness to run separated TCU/ECU, and find the correct option for each of those.

This is what these threads ALWAYS come down to. Sure, you can get all the hardware in, but actually getting an ECU that'll run it right is where it always falls apart.

Yes you can use a CR-V harness in a '99 - '00 civic at least with a 5 speed. I proved this years ago. However you'll still need to deal with the distributor plug since '99 - '01 CR-Vs use the same small pin distributor plug that '99 - '00 Civics (Except HX/Si) use. You can always build a distributor using Y7/Y8/B20Z CYP/CKP/TDC sensors in a B-series vtec housing to get around this, or maybe use a '98 CR-V harness (I believe it to be both OBD2B and use a large style distributor plug for that one year only)

Pics of my buddy's car we put together years ago:





Also, some of those 6th gen JDM and Euro Civics came with a B16A automatic combo and these have the proper shifter and shift cable for your car so that if fits the hole in the center console properly.


Best bet is a JDM/Euro Civic B16A OBD2B automatic ECU (which do exist) From what I recall they have an integrated TCM.

tony_2018

^^^ This.

If this was a b20 auto it be a simple swap in, just like what you did, and used the crv ecu.

I see why you did what you did but trying to use an p2e/p2p ecu will throw a cel for the transmission, something to do with the automatic gears.

I hope you haven't given up on this project. Just checking up on what you're plans are.
