Hey everyone, my 93 jdm h22 swap is almost done. everything is attached to be started. The clutch pedal is dead and i think it needs to be bled. I'll be doing that 1st thing when i im off work. May have to replace clutch master cyl. also.

I grounded out the external ignition coil becuz the h22 has an internal one.
MY QUESTION: Will the p13 ecu programed to USDM specs i have work with this motor and its dizzy?

 

itll work but youll be throwing codes, wont crack vtec, and run like ****......

Heres a link. someone had told me to do it this way and that it should work. take a look... what do u think?

 

just get a chipped p28 cuz jdm motors dont havea few things that usdm motors have

 

Like what? The ecu i bought off a guy that programs ecu's out in the SF Valley. The ecu i have isn't an actual p13, idk what ecu it is but he has programmed to a usdm p13. I called him and asked if the ecu will run a jdm motor and he said it would be fine but i should use 91 octane at the pump.
Is there anything else i would need to worry about?

 

just plug it in and start her up........you'll know if something aint right

 

it wont be right if its for usdm, because of the egr block off and no 02s on the jdm motor

 

I have a jdm h22a, running a jdm p13......it looks for egr....and I even put a block plate in and no cels....the usdm should work just fine.....there isnt much difference in jdm and usdm p13's........the mystery is what exactly did your tuner guy put into that ecu.........the ecu don't care about if you have a external or internal dizzy..........just get your car started first,...then troubleshoot the cel's if you got 'em.........

I just went through all this myself........you can still hit vtec with your cel on.............because before I fixed my egr issue, I would get code 12 at high rpm......but I would still hit vtec......I didn't think vtec would engage with a cel.......but it does.....even while running a stock jdm p13

 

only some cels let vtec crack but if its not safe some cels will not let vtec pop

 

good point,...you are right about that

 

My JDM H22 had the EGR and O2 on it, and the USDM P13 will run it just fine. Where do you get this backwards crap?

 

He does not know himself from lack of experience lol. if the ecu is reflashed i'm sure the guy disabled the second 02 and fixed the egr problem. just about ALL the ecu's from the same model will work in other cars(with some exceptions) as long as they were modified and reflashed to work your vehicle, dont NEED a p28.
