D16tuning

hey katman, i have a 96 civic lx with a z6 mini me and i have the ckp code gettin thrown and i have replaced the ckf sensor i think its called by the cam pulley and i have reset my ecu and still the code gets thrown but.... i have a 2000 y8 dizzy on it and im NOT ENTIRELY SURE if the wiring is correct i have looked and looked and still cannot find a decent pic on how to wire a ond2b dizzy correctly to a obd2a harness. and i cant buy a obd2a dizzy cause im pretty tight on money so can you help me out??

THANK YOU! this helped me out alot!

Katman

Yes, you can reuse the following EK civic mounts/brackets on a B-series swap:

- both mount on underside of frame rail
- TOP tranny mount/bracket
- rear engine mount
- driver side mount and bracket

Good to hear you bought the rear bracket and driver side mount.

From the LS brackets you just need the front tranny bracket and A/C bracket, and you're set.


From the LS you will need the fr

hey katman i just got done reading your info and i have some ?
i'm doing a 96-97 jdm b18c r swap into a 96 civic dx can you tell me
what i need (item) and what i need to do to get this going....

this is what i have

96-97 jdm b18c r it has the o-re-g-no wire hardness hook up
and cut form the wall. (should i use the dx's wh?)
i also have mounts
the jdm ecu ....

and if you could give me a step by step swap info
thanks...much thanks....

hey katman, from all 12 pages here, you're very helpful and very knowledgeable, but i've run into huge problem that i see a few others have run into as well, but i dont know if my problem is the same or not.

what i have is:
98 HX coupe
stock EWH
had a d15b vtec dropped in, wired the vtec with no problem, been driving but wanted more power

pulled motor out and now putting in b16a obd1 complete swap, everthing wired up, only thing i've run into is dizzy...

at first car would only attempt to turn on (turn) with no spark. we pulled the d15b dizzy and car sparked. we put the d series module into the b16 dizzy and car turned on for about 10 seconds, but was really rough then died... never saw this car turn on ever again. smelt all the modules and they're all burnt, or smell burnt at least.

i feel that there may be a short somewhere?? i have a ground hooked to the valve cover to my chassy, then on the tranny side too. is there suppose to be another one? where?

how do you wire up the obd1 to obd2 harness, where the colors say "obd1/GREEN, obd2a/GREEN, and obd2b/GREEN" i dont have green to green, i have like green to orange/something.. i forget. but i guess those are the last remaining wires to go together? i need a picture, i'm more a visual learner.

uh.. what else? my car just wont start i'm so sad.. help?

Katman

First off, don't be lazy - read the very first post of this thread. I explain what's needed to get an OBD1 engine installed into an EK chassis. It's not quite hand held step-by-step information, but more of what's required to make it work. You can search the forum for a hand-held step by step if you're a first time swapper.

As for wiring, you need to use an EK engine harness for the swap. You can't use any kind of Integra harness (ie. the one that comes with your ITR engine) in an EK because of its 2-piece design. I highly suggest to run a 96-98 EX harness for your swap to minimize on wiring procedures.

The JDM ecu will plug directly into your EK because its OBD2a spec which is what all US 96-98 civics are. No need to worry about the 2nd 02 or the CKF sensor wiring when using a JDM OBD2 ecu either.

sup katman i spent the weeken...to swap motor..it went in well..
i know you said to use ex ewh but i dont have one so i use the dx's
did some cut and add...every thing seem to work..

i start the car and it fire up but when i hit the gas it want to die
and shut off ...if you could help thanks...

Katman

are you getting a check engine light at all? if so, find out what the CEL code is and that will help pinpoint the problem hopefully.

Also, did you perform the IACV fix being that you reused the DX harness?

also, whats the part number code on the side of the ECU you are using?

just1

yes there is a engine check light...new at this... how do i find the cel code

sorry but what is iavc...and how do i fix this?

i took out the spark plugs and the tips were carbon black...?thanks

Katman

the carbon black spark plug tips are more than likely due to the fact your car is running rich because of the ecu being/running in LIMP mode because of your CEL.

read here on how to check a CEL code:

IACV fix is explained in these 2 diagrams here:

katman thanks alot for the info every thing you post up is very clear
i did just what you say and it work out perfacto!!!!!!

so you say if i were to use ex ewh it would be alot simple
just got one more ? i use the dx ewh and did the iacv fix .....ok now when
if i choose to us the ex ewh do i need to go back and undo the iavc fix?

thanks alot you where very helpful

lets hopes there is no more problem....thank again..

Katman

Good to hear

If you pull out your DX ewh and replace it with an EX ewh, you don't need to do anything with the IACV fix - the 5-speed EX harness is already pre-made to be used with a 2-wire IACV from the factory. And don't forget that all EK ewh's are a 1-piece design. So when you pull the DX ewh, its the whole thing including the ECU plugs where you've performed the IACV fix.

thanks so much you are a honda swap god
one more ? is it normal when i'm going 70-110mph the temperature climbs up then when it slow down the temperature is back to normal..

This distributor wiring is confusing the $h!t outta me lol!!! I have a b18c obd2a thats going into my obd2b 99 EX Civic. I am going to be using an obd1 ecu, therefore obd2b-obd1 conversion harness.

-I have a obd1 and/or a obd2a dizzy plug that I'm goin to have to use for my gsr dizzy right?? I have both. I do have the obd2a GSR harness, so I can just use the dizzy plug off of that? Aw poo I'm just confused. I have the y8 obd2b harness and dizzy, and I have the gsr obd2a harness and dizzy. Which plug to use?? Its going into a 99 obd2b using an obd1 chipped p06 ecu.

So, splice the plug from the gsr harness onto the EX harness? I guess this is where I'm tryin to get at ??!?!??

-I read something about the tach is controlled by the obd2b ecu, but since I'm converting to an obd1 ecu, what am i to do??? My tach wont work??

Katman

you could buy an OBD2 to OBD1 dizzy jumper if you really wanted to

I'm working on an updated dizzy diagram at the moment that shows where to pin each wire to each pin slot for manual OBD2-OBD1 dizzy conversions...

Xscort

I'm still going to use my obd2a dizzy that came on the gsr, but I'll be using my obd2b Civic EX EWH. So should I just cut/splice the dizzy plug off of the GSR EWH-->>EX EWH?

I'm assuming thats what I'm to do, but as far as the tach goes, since I'll be converting to the obd1 ECU (i already have boomslang obd2b-obd1 harness), I'm going to have to do something about wiring the tach since it won't be controlled by the ECU???

Katman

yes, I would use the OBD2a GSR dizzy 'big' plug (from the engine harness), and adapt this over to your 99 EX EWH (which has the 'small' style dizzy plug).

As for the tach, just take care of the GSR dizzy plug swap for now. Plug in the jumper harness and OBD1 ecu and see what happens first. If there is no tachometer operation, then yes, you'll need to add the RPM signal wire.

hey katman, i just swapped a b16a obd1 into my 98 hx coupe, i don't have AC or the compressor doesn't turn on when i use the p30 ecu with the conversion harness, but when i put any obd2 ecu on there, a/c is available again, is it something wrong with the conversion harness? can't be fixed at all? or is there a pin configuration i gotta do?

eohagan

katman you are a god ... can I assume you know f-series too?

my swap: obd1 f22b into obd2a '97 acura CL, need to pass smog
i'm stuck at fuel no spark - had to jumper 2 pairs of CKF wires to get fuel, have not seen spark yet. Was told to buy an h23 dizzy, wouldn't plug or fit, took it back. Have usdm CL dizzy and the dizzy that came on the motor (one is 5 wires other is 7) don't know if i can cannibalise them into a working one, replace, convert to obd1 ecu (unclear if this will pass cali smog)

I appreciate any help you're willing to throw me

Katman

could be a faulty jumper harness design, I can't say though. WHo's the maker of your jumper harness? You should contact the maker and see if they can provide you an answer.

Katman

aww thanks....but no, I'm just a simpleton.

I'm sorta versed with F-series knowledge (still learning at the moment).
Well, i'm not sure if you can pass being the short block is OBD1 (older than your vehicles year). Normally, the engine has to be the same year of the car or newer, in order to pass.

But, I believe the CKF might be the culprit here, and when performing the CKF trick, I don't think its the same as it is on say an OBD2a/b integra when doing this trick...in fact, I'm not even sure the CKF trick even works on the prelude/accord/CL platforms. Thing is, if you cover to OBD1 you shouldn't have to perform any kind of CKF trick at all as OBD1 ecu programming doesn't look for the external CKF sensor.
Perhaps your igniter is bad?? try swapping it out with on of your dizzy's?

useful information thanks

Question about the OBD1 Distributor, does it have a CKP sensor inside of it? as opposed to the OBD2 Distributor where the CKP sensor is external?

I just swapped a OBD1 B18c1 motor into my OBD2 98 Integra GSR. There is no spark, Im trying to use an OBD2 distributor <it plugs into my OBD2 harness> but im wondering if there is no spark is because the OBD2 doesn't contain the CPK or TDC sensors the OBD1 ecu is looking for? or am i off base in my thinking.

ok dont flame me lol im tired and just ran into a bitch of an issue that i have yet to see in all my years of doing motor swaps. first off the car being swapped is a 99 ex coupe. doing b20 vtec swap for a kid. head is from 99-00 si, came across an issue when i noticed that the distributor plug on the harness is tiny and will not fit any b series dizzy plug. so i went ghetto and hacked the plug off the original d16 dizzy and attempted to splice it onto the b series dizzy. almost everything matched up fine until i got to the light blue and yellow wire on the dizzy and the dark blue wire. noticed that the light blue and yellow wire had silver wire in it and there was only one wire left on the d series dizzy plug that had silver wire in it so i spliced it together. (this was simply an experiment cause the kid plans on buying a new distributor) well i ended up having only the dark blue wire left (copper wire inside) so i left it hang. car fires up and is not throwing any kind of ignition or firing code. so my question on that is uh is that gonna be ok? also we are using obd2a y8 ecu still till his p28 and harness come.car is hitting vtec but is throwing a code for the vtec spool solonoid, my question for that is why is that code being thrown? is there a conflict with the y8 ecu? car is only throwing 3 codes (primary 02 which i can fix, ckf no duh, and the vtec spool solonoid). please excuse my grammar or lack there of and my lack of knowledge on this, never seen that little plug before or dealt with obd2b. any help is appreciated.
