we tried everything in last 24 hours to make my mpfi work and we got nothing.. ive got both the dx and si wiring harness for the engine.. and i went and bought a "body or ecu" wiring harness from an si also we always seem to have left over wires ARGH it cranks but it wont start.. bleh whats those one sites again that help? i need one with pictures so i can print it and show it to my friends.

 

btw i searched for the thread and found a lot but i cant find any site with actual pictures.. i know there is one tho cause i saved it at work

 

http://tech.hybridgarage.com/tech/4g...-zc-wiring.htm

do a search on there

 

dangit somebody posted it on here.. but i lost the link grrrrrrrrr it was a one page site with info and pics it showed all the wiring i need and everything

 

uhhh u should have never messed with the interior harness or the dx harness u should have modfied the engine harness and thats it

 

was that the one out of the (i think) sport compact magazine???

 

no no it was a site that showed which plugs should be left over and the resistor box and some wierd **** as for the dx interior part i put my old one back and my old dx harness back too now i gotta figure out whats wrong.. btw if i got a mpfi from an hf (i think the junkyard fucked me over) will it still work? a guy here did a mpfi swap with a dx distributor but i think he got dif plugs or someshit i dunno what he said.. unless whatever he bought came with the si dizzy.. how much do si dizzy's normally go fo and shouldnt it come with my intakemanifold and injectors and stuff? i hope if i got the hf mpfi it will still work..

 

wait do i use the engine harness .. the dx one or si one? ive got the si and dx engine wiring harness..

 

u have to use ur stock harness and modify it like stated in most every post about this do a search

 

k so i use all dx harness... complete.. and just modify it? bleh... anybody here want 20 bucks? heh ill send s 20 doller check to anybody who calls my house and helps me and my pals do it by phone and ill pay the phone bill too.. im in seattle wa.. anybody interested? just help us with the wiring part.. thats it.

 

whats EACV stand for? and tps is a sensor right?

 

Loock up some of my old posts. Maybe they will help you. Good luck.

 

i just finished my mpfi swap yesterday, it didnt take too long, had a lot of problems with the wiring , i was throwing code 16 , so i rewired all my injectors straight to the ecu, you also might want to double check your diz wiring , it can get screwed up pretty easy, i took the si dis plug of and switched 1 wire at a time to the same color wire on the dx plug. the car runs great. .... i know someone with a whole si swap, trans, ecu, intake mani, tb, all sensors, everything you need if you got the hf stuff.

 

did you remember to switch teh wires on the tps cuz the tb turns opposite direction on the dx .

 

well my **** says pgmfi or whatever on it just like the si.. so i would think it would work the same if i had the si ecu since it has 4 injectors or whatever .. nobody wants to help me on the phone or maybe on aim? so i can explain each problem while i come across them lol this is getting very annoying and im disliking every second of it

 

i think i got a dx distrib i dunno bleh.. so nobody can help us on aim or on the phone? my car will be no more then 5-10 feet from the puter/phone cordless

 

my aim is joshwhe, talk to me if you want. the hf and si both say pgmfi or what ever, the hf intake runners are super small and if you put them on your gonna lose power instead of making power, the hf makes like 62 hp dx like 80 and si around 100, you should have gotten a diz when you bought all the stuff, the mpfi diz needs a crank pos sensor thats how the mpfi works, sequential ingnition **** , anyways you need the si diz cuz it has two wires that go to the ecu to make it work.......

 

how many wires are coming from the distributor.. there is a 2 wire plug.. then a bigger plug

this is off my head.... the dx has 5 wires and si/hf has 7 wires.

 

Sport Compact Car did have a hybrid how-to that showed the MPFI switch. It's the June 2002 issue

 

You need an si or hf distributor, it will start with the dx dizzy but run real crappy and it won't rev past about 3k. And yes the hf mani works, but has less flow than the si one so you woun't get the power that the si intake offers.

Do you have:
si or hf ecu?
si or hf injector resistor box?
si or hf dizzy?

If you want to haul the car down to Oregon, I'll help you out. It's been a while since I did mine, so I'm not sure if I can guide you through sight unseen over the phone.

You sound pretty rushed. I have said this about 50 times on this site, but I'll say it again. A novice needs plan to have his car down for at least a week to work the bugs out while performing this swap. There's always parts forgotten or parts broken.

The Throttle Position Sensor (TPS) is the electronic sensor that's mounted on your throttle body, and the Engine Air Control Valve (EACV) is on the backside of the intake manifold (#10 in the photo below)



Speaking of this photo, the webside I stole it from ( http://www.hondaautomotiveparts.com/...KA5MT&catcgry5= ) has a lot of good drawings like this that I find very helpful in identifying parts. Nothing there to help your wiring woes though. I followed the Hybrid's site mentioned above and had no problems whatsoever with my wiring, the SCC article I accually found more confusing than anything.

 

where in oregon? how much money do u want? and are u 100% sure u can do it if i got all the stuff needed? im interested... u couldnt come up to seattle? ill pay for ur gas and pay u also how about it?

 

I live about 1 hour south of Portland on I-5 and I work a split week, so I never get 2 days off in a row (I'm off Wednesdays and Sundays) I Can do the swap for you easy enough, but I don't think I could drive up there, do the wiring, and drive home in one day. Also, I'm not sure if I can trust my hatch to make that kind of trip right now, It has this little problem of dumping oil on the clutch at high rpms (which is any time on the freeway with a 4-speed) I wouldn't need any money from you, I'd just do it to help out a fellow H-T member. But If you have the car torn apart, You'll need to figure a way to trailer it down here. Being a trial member, you're probably about to hit your daily limit of posts. feel free to email me, or if you have MSN messenger I'm on there: thumpu77@hotmail.com

 

my big problem with my mpfi swap when i did it on the zc swap, was when i added the one wire at the ecu, i never took that white thing out to put the wire in, i just pushed it in, lol. But after that it was fine. It started though just ran shitty.

 

mr madeiniraq is right
haha
he helped me out with mine

 

how do i become a real member -_- lol and um so theres no way u could come up here to do it? i can have my friend do the engine mechanical part all ugotta do is the wiring.. and ill give u some $$$ plz o plz? lol im getting my si dizzy soon too
