SmokinH22CL

im gonna let yal know the whole story...

right now i am using my CL ecu to run my h22!! for some reason my p13 ecu isnt working.. i have a obd2b-obd1 conversion harness from rywire, i used the conversion harness with my chipped p28 and worked fine.. but before all this i used to have a apexi vafc1 installed with the CL ecu runnin the h22.. I had a local shop properly uninstall the vafc for me and i noticed that i have spliced wires on my harness, im sure that its from the vafc.. so after that i hooked up the conversion harness and my chipped p28 and im all good.. well i ended up gettin tired of it cuz i wasnt happy with the way my car was runnin (vtec wasnt how it used to be compared to the vafc) so i decided to get rid of it and go a different route, turbo!! but that didnt work out the way i wanted it to.. my tranny wouldnt go in reverse and my clutch went completly out.. so i had to replace my clutch and tranny..
so anyways now my clutch and tranny is all good i recently found me a obd1 5sp p13 ecu. i hooked it up and reset and everything properly. then few min later when i start my car i get this wierd idlein, i guess thats normal.. then after a couple minutes my car idles really smooth so now im like hell yea ready to ride out and feel the vtec! but no, when i step on the gas my car cludders really bad and aint goin nowhere.. so now im back with my CL ecu and no vtec cuz the p13 isnt working for some reason, i dont have any clue whats goin on.. i thought it should of worked fine.. if anybody know whats goin on or anything please let me know!!! Thanks

btw i hope somebody here knows whats goin on.. i posted on h-t a couple weeks ago and one guy said i might have to swich some wires on my harness, can anybody confirm this?

Sounds like the splicing/hack job from your vafc is to blame for sure. Sounds like some bad wiring, if I read all that right, it kinda hurt my brain

Humm, the p13 and and the 28 are different so wouldnt that amke a difference in how the harness is connected to the Ecu??

Arnt there different Pins??

SmokinH22CL

yup could be.. but then i dont know how my chipped p28 worked..

both ecu's are obd1 and they both plug in the same as long as i have the conversion harness..

SmokinH22CL

another thing i'd like to know is how my CL ecu is working?? oh yeah and another thing is i have no VTEC!!

SupraManAG

well you can come here and ill tell u if my h22 works with your ecu. you can test it then. honestly sounds like you have a short somewhere. there would be no reason for a conversion from P28 to P13 to make the car not start. the pinouts are the same therefore it should run. btw. are you looking to sell your P13? and is it JDM?

teh CL

u want a P13? i got one if you want

SmokinH22CL

im actually thinking about selling it soon, and its a usdm. now thinkin about gettin another chipped ecu from my local shop and just have them figure out my wiring issues..

wilp99

you can get a p13 out of a 96 prelude, it was the last year for the obd2 p13 with no start chip. i did a frankenstein on my boys 96 (h23 to g23) and we had to find one.. very hard to find.. but it worked perfectly. the p28 actually is mapped out to give you more power out of the h22 but when you hit vtec it will fall on its face. anyways, try and find a obd2 p13 and you wont even need the conversion harness, and you can put that turbo on. good luck pimp..

SupraManAG

how much?
has to be JDM

SmokinH22CL

i wish i can find an obd2 p13, it will work for a obd1 engine correct? but what about my obd1 p13?? i thought that should of worked fine.. i still dont understand why it doesnt...

SupraManAG

it should
with the conversion harness it should work just fine
listen
hook up the p28. if the car runs fine then the ecu might be bad.

SmokinH22CL

i sold my p28 a few months ago.. i jus thought of finding somebody local with a prelude or an h22 swap to see if my p13 is bad or check their ecu in my car vice versa to really find out if its the ecu.

And if i did ever find a obd2 p13 then i think i have to convert from obd2b-obd2a right??......

wilp99

im not 100% sure but obd2b came out in 99. i think. is the stock cl ecu obd2b? i know they are different. and they do sell a conversion harness for that too.. or you can just get the pinout of the obd2b and obd2 and re-wire the harness. but like supermanag gaid your harness whould work with the obd1 p13.

wilp99

and the obd2 p13 will work on an obd1 motor.

SmokinH22CL

yeah my ecu is obd2b, it uses the left 3 plugs.. damn i guess i just need to find somebody around here to check my ecu since it should work.. its a very clean p13!!

and just in case i might have some wiring issuses here are 2 links this guy on h-t found. what he came up with is a11 stays empty. switch b7 on acura cl pinout to a6 on p13, and switch a20 with a12 is this right?? the cl ecu is an obd2 and i believe is the same as an accord obd2. here are 2 links he found showing pinouts
for h22 p13

and for acura cl

can anybody confirm this? and doesnt a conversion harness take care of all that or what??

SmokinH22CL

man this stuff is confusing!!!!!!!


EDIT: i noticed the 2nd link doesnt work.. maybe this one will work..

You must be getting some sort of check engine light to help you diagnose this on either the OBD1 or OBD2 ECU?

First and main difference is your CL ECU (OBD2) wants to see a 3 wire IACV and your P28 and P13 are only looking for a 2 wire IACV. You H22 most likely has a 2 wire IACV...

What that has to do with VTEC...well nothing really except for OBD1 ECUs with wacked out IACV CEL lights like to completely muck up how a car runs.

SmokinH22CL

i didnt really understand what your tryin to say... but anyways yeah its throwing cels, misfire in all 4 cyl., vtec malfuction, and some other stuff, im sure its just becuase im using a CL ecu on the H22.. i dont know but this stuff drives my brain crazy!!!

my chipped p28 worked fine with no cels.. and the p13 also no cels but it just wont go, when i step on the gas my car cludders really bad and aint goin nowhere.. its weird, but i guessing my p13 might just be a bad ecu.... ill find out sooner or later.

No one can just chip a P28 to just 'work' for you...especially with an H22. It is possible to get it running correctly with tuning though.

What size injectors are you running? Stock H22 injectors came in 290cc, 310cc and 345cc...so you need to know that for making the P28 chip. If you reused your stock CL injectors, this might explain why the CL ECU seems to run ok (with a ton of CEL codes obviously) but your P13 and P28 ECUs 'just wont go'

If the P13 and P28 ECU are setup to be running injectors larger than your stockers, you will be running way LEAN, lowing tons of power and possibly detonating and doing damage to your motor.

Believe me, I have tuned numerous stock H22 motors and chipped well over a thousand P28 ECUs. If you knew what size injectors you had exactly and wanted to send in your ECU, I could take a look at it for you & probably set you up with a little better base program. From there you should take it to a local tuner and get everything dialed in...you will be much happier in the long run doing it to right way.
