Nice work jon but not necesary to change your injectors to obd1 you can leave your obd0 and resistor box and it will work fine💪👍

@GarageBuiltHondas 6 лет назад

Thanks for that great info!! I wanted to get rid of that ugly box. 😁 I'd like to eventually get a tucked harness too so for me it was about trying to get the bay cleaner.

@jasond4752 5 лет назад

Is there any added functionality with the OBD1 injectors or no difference at all?

@GarageBuiltHondas 5 лет назад

It's required to go obd1, but no added benefit stock. However to make it easier to tune, going obd1 is the way to go. Not many options, if really any remaining at all to tune obd0 ecus.

@jasond4752 5 лет назад

@@GarageBuiltHondas Ok, so the previous comment (RT Motorsports) saying it's not necessary to change them when converting to OBD1 is incorrect?

@GarageBuiltHondas 5 лет назад

I should've phrased it better. Are you familiar with the 2 different types of injectors? One works with a resistor box, the other doesn't. He is correct in his statement, I prefer to use obd1 injectors as you'll then have the clips needed for a wide range of other "upgraded" injectors. What setup are you going to have?

@PlasticDrummers 2 года назад

For everyone wanting to do this conversion for the cleanest result. Don’t cut your wires!!!!! You can de-pin every plug and change the plugs over to obd1. Without ruining your harness or having to solder. The only wires that will need to be soldered is the 4 for the new o2 and the 2 for the vtec solenoid and pressure switch and 1 for knock sensor. Single cam motors 92-95 don’t need knock sensors The only time you’ll need to cut wires if you’re doing a dpfi to mpfi on obd0 Automatics can also do the mpfi swap into Efs as well non vtec and vtec A stock d15b2 crx dx bottom end with 1.6l zc non vtec cam slapped into the head converted to mpfi and a pm9 ecu header and short ram will hold its own against a stock crx si. It will pull from it on take off And a d16z6 conversion with auto p28 ecu holds its own as well While autos aren’t the fastest there’s a bit of fun to be had for those who don’t want to drive manual or can’t.

Hello, very informative video, I have bought a converted civic to obd1 and o2 sensor is actually with only one wire coming out of it, it started to throw code 43. Can it actually be ok if I put other same one or should I look for wires that should be for the sensor you have and use the one you do?

@Norse1957 4 года назад

I'm a bit confused by the discussion on the injectors. I have a 1990 CRX Si, and I'm putting a '98-'01 H22A, which I guess is OBD2, so should I go get OBD1 injectors and adapt my D16 injector harness to those? Or can I run the OBD2 injectors?

@GarageBuiltHondas 4 года назад

Which ECU are you using? Use the corresponding injectors to go with your ECU. You can use whatever you want depending on any conversion harnesses you want to use. It's up to you.

Hi mate, Hoping you still read these comments. did a JDM D15 swap dual vtec, into a 1991 HF CRX. Have the Rywire harness, everythings hooked up. No resistor box due to obd1 injectors. We are not getting any injector pulse, car starts on starting fluid but wont start without it. Has spark and fuel, just seems to be an issue with the injectors not pulsing. How do we fix or trouble shoot this? cheers

Hello, nice video but I have some little different questions. Im running eg4 (dpfi OBD1 sohc) and I'm planning to put D16A9 (mpfi OBD0 dohc), so i need (want) to chage motor wiring to OBD1, So I need to replace distributer with OBD1 one, replace thermostat with OBD1, use OBD1 injectors, 02 sensor with 4 wire (instead the OBD0 with one wire)? Im planning to use d16z6 motor installation wires and my tranny (because I want to stay with hydro not cable one). Do I need anything else? Do i need to add some wires to my original car installation because dpfi to mpfi? (Car installation is stock from b2 engine, and the motor installation will bi swapped with d16z6 one. Also which ECU i should run? Can i use harness OBD1 to OBD0 ECU? Or i can run some other OBD1 sohc mpfi ECU like from d16z6 or d15b7? Thanks a lot. Greetings from Croatia!

@GarageBuiltHondas 5 лет назад

You'll need to first do a dpfi to mpfi conversion and also use the obd1 conversion harnesses. That'll get you set up to running the engine correctly. Easiest option would be to use your existing wiring harness and convert it to be mpfi. Using a harness from an mpfi car will not work unless you use the underdash harness also.

@DJV94022 3 месяца назад

The combinations of errors of these ebay harnesses is crazy.there is a bad batch scenarios where sensors are pinned in extreme wrong places and missing wires..in my case my 1st ebay ecu jumper harness cyp and ckp came out with the wires being pinned wrong.and missing a alternator wire 5v reference..i bought a 2nd one and that one was worst.so i took a wire out of it to install into my first harness which was alternator signal wire b5 to a16

@GarageBuiltHondas Год назад

Under the dash? I'm not 100% positive. I believe they do though.

@justinsimons5367 4 года назад

Does the fuel injector apply to a d16z6? I have an ef hatch swapping

@GarageBuiltHondas 4 года назад

Yes. You'll use whichever injector is needed if you either want to keep the resistor box or not. In your case, I'd go obd1 completely and remove the box.

@russellniven6215 5 лет назад

Just asking why do you have to change the dizzy I have a 1990 b16a obdo vtec

@GarageBuiltHondas 5 лет назад

The obd1 distributor is different than the obd0 and they unfortunately don't work together.

Would this work for an 87 prelude Si ?, I have an odb0 fuel injected a20a3. thanks!

Can I buy the o2 sensor, knock sensor, etc sub harness separate? I am missing the extension harness….

@GarageBuiltHondas Год назад

I don't believe they make a sub harness just for those. Most como only sell entire engine harnesses.

@honda_bandit6603 4 года назад

so what wire from the sub harness wires into the second black wire into the o2 connector

@GarageBuiltHondas 4 года назад

Either black. They are both grounds.

@carloszapien9296 6 лет назад

no need to swap injector clips. you can use your obd0 injector clips on an obd1 injector. you just have to trim the inside piece. a lot cleaner this way

@GarageBuiltHondas 6 лет назад

Well shit, I knew I could use obd1 clips on the obd0 Injectors but not this way around. Thanks for adding this CJ!!

@GarageBuiltHondas 6 лет назад

I don't know why it didn't register, trim the two corner tabs off of the injectors, right?

@carloszapien9296 6 лет назад

no. i trim the inside of the obd0 clips. i use bosch ev1 (same as obd0, hard to find new obd1 specific clips idk why) and just trim the inside corners of the center pice and done. use my trusty dremmel. i can email you pics if you like.

@GarageBuiltHondas 6 лет назад

Awesome, please!! garagebuilthondas@yahoo.com. I was looking at getting one of your wiring harnesses when you had them on sale a couple weeks back but didn't have the money to spend. I'll definitely be getting one in the future! I didn't know you followed me on here and am flattered that you do, thanks! I gave you a shout-out in a video a few weeks back where we installed a JDM front end on to my friend's crx, you had made the headlight conversion wiring harness for him. 😀

@isaiahraybreeden4228 4 года назад

What is it doing to connect all those wires from the restrictor box? Doesnt cause a short or something?

@GarageBuiltHondas 4 года назад

It doesn't. It's how the new injectors power supply need to be since they are a different kind of injector. You're going from "peak and hold" to "saturated" injectors.

@HiFiInsider 4 месяца назад

is there a way to convert OBD1 to OBD2? I have a 95 civic with OBD1.

@DJV94022 3 месяца назад

No one does that..however if you have everything on your engine or your entire engine is out of a 96-01 then you need obd2 engine harness with obd1 ecu plugs

How do i run injector wires if my car dont have a engine and has the dpfi harness and no resistor box ?

@alexanderivy3482 2 года назад

@rexx2279 2 года назад

21:55 any insight on installing a 3 pin dlc ? was looking to use a hondash device

@GarageBuiltHondas 2 года назад

I don't have any experience with that.

@dummyjum 6 лет назад

Ones again my dude, You killed it haha! Good shit man! This conversion obviously gives you some power gain but did you notice any? Dyno tune very soon im sure?

@GarageBuiltHondas 6 лет назад

Dude, it felt much stronger at the track. The biggest inclination was this part of the track where it's a long straight, I normally would get to like 95mph but I seemed to be hitting close to 100mph which seemed different. I did however than my fastest outing ever! It feels really good!

@dummyjum 6 лет назад

Garage Built Hondas Haha that's what's up dude. Tune it now and get all the horses out of your bolt ons my dude. Since your obd1 now. With this obd1 conversion you're definitely getting more out of this motor. Tune it with Crome or Neptune.

@GarageBuiltHondas 6 лет назад

I can't wait, been talking to RT Motorsports also and may try out a COP setup before tune but after cams. Hoping this motor is pulling hard by the end of the summer!

@dummyjum 6 лет назад

Garage Built Hondas so your planning on camming this built?

@GarageBuiltHondas 6 лет назад

Yes, I've had them since last summer. Was something I wanted to get in earlier but just have had so many other things I needed to finish. If I wouldn't have swapped shells I probably would have been done already too.

@andruwwilson8367 3 года назад

Do I need a 4 wire o2 sensor or could I run without it for a while

@GarageBuiltHondas 3 года назад

It should still run with a CEL. Not sure how well it'll run though, might get crappy has mileage and run rich too.

@leepeezy 4 года назад

I'm doing this conversation and I bought obd1 injectors and went to change them out and the plugs fit without changing them they just plug right in I checked and the injectors I pulled out are low impedance

@GarageBuiltHondas 4 года назад

👍

@carbon310 2 года назад

Did that's with the mpfi swap on my zc single cam EF. But won't start. When I turn the key, there is no cel. I'm assuming I don't have power to the ecu or it's fried. Can anyone help?

@GarageBuiltHondas Год назад

Check for fuel and spark.

@wickedeagans 2 года назад

Now the car is switched to obd1 one. What to do when engine light is on😩 90 civic wago with d16z6 ob1 conversion with chipped crome ecu I pin the blue connector in passenger seat and light just stays on

@GarageBuiltHondas 2 года назад

You'll need a non-chipped ECU. Or download crome and look into what the CELs are on for.
