Angry dpfi to mpfi help....

Ok, I'm stuck my cars new engine is ready to run just its waiting on a wire harness. I have a new ecu thats for the motor and thats it. my old motor was a D15B2 dpfi and my new motor the D15B7 is mpfi and i cannot find out out to get my car running because of this. as of right now i only have 80 cash and wont be getting any any time soon. so my only plan was to go find a D15B7 at the junk yard and pull the wires from the ecu all the way up to the motor and take them home and connect them to my new ecu and to all the sensor on the motor. is it as easy as that or is their more? someone explain plzzzz. im stuck.

travis..sounds like either way you'll need a conversion harness.. unless you can find an si harness obd-0 (88-91) there are also a few write ups on how to do the coversion your self.. search it.

Why you say that? a entire harnesss from the junkyard will be a direct swap shouldn't it? everything connect like nothing? what would i need a conversion harness for in that case then?

your car is obd-0. Like I said, unless you can find an si harness(obd-0 mpfi) you can do what you said, other wise you will need to convert. mpfi harnesses are mainly obd-1 and later. So if you go to the junkyard and find an mpfi harness it will most likely be obd-1 . Again, do a search for dpfi-mpfi, there is detailed explanation and you can get a better understanding of the difference.

Ok, i found a great writeup on this but i need help.

as of right now i know im going to have to buy a soldering gun and heat shrink thing, extra wires and a injector resistor. but what my question is am i going to be using my stock ecu or the one i bought with my new motor???

also, changing a few wires on my ecu and swapping the wires on the tps sensor backwards, and putting in a injector resistor and running the new wires to the new injectors and extending a few connections. is this the only thing i have to do even know i put it in likes its easy???


CAN I JUST GET A INJECTOR RESISTOR BOX FROM A JUNK YARD OR EBAYMOTORS???
and the only thing i know i need to buy as of right now is a injector resistor. is this correct? and if theirs any other stuff i need to buy plz let me know what it is and why i need it. THANKS !

what injectors will you be running? You can use the obd-0 ecu if you are staying with obd-0 injectors. You dont need a "new" resistor box but it wouldnt hurt. List all the components you will be using and members will have a better idea of what to suggest. You mentioned a d15 motor, but nothing about which components. Be specific.

You can run obd-0 and obd-1 components together with a little fab work.

Gets a little frustrating doesn't it, prpprimo?

Travis, do yourself a really big favor and wait to do the MPFI and OBDI conversion when you can afford to do them. You don't seem like you're ready to build an OBDI conversion harness. Have you noticed that your OBDI ECU has three female plugs and your stock cabin harness only has two? You'll need to do something about that, which is what the ECU conversion harness is for. Put your D15B2 intake manifold and distributor on the B7, use your stock PM5 ECU, and call it a day.

That's what my motor build was. It was very functional, and treated me well. Didn't have to worry about anything else, either.

Sad part is, you will probably still end up chopping and splicing wires.

you didn't even have to cut a lot of wire. You already had two injectors, therefore already had two injectors wired in. What's so hard or confusing about wiring in two more?

If you couldn't find help, why take on something you don't know how to do? Don't take this personally but so many people dive in head first without filling their brain first... I don't know how to do plastic surgery but I love titties, you don't see me trying to go around giving breast implants do you?

I'm with these two guys. There's also a wealth of information on this subject and you just made this 100% more difficult than it needed to be. Put your dash back in and do it the right way.

Well i bought a Si ecu PM6 out of a crx si for $37.99 and the engine harness only for $27.99 and all that money was wasted when i found out it wasn't just plug and play. so after that my internet got turned off and i had no axcess to the internet so i went the way i know how and been workin since. the only thing i need now to start the car up is the under the hood fuse box and the distrutor and ignition key. after that i have to figure out how to wire all the lights up and blinkers. but from i have read wiring up the wires on the stock harness seemed difficuilt and long and boring.

And you think you made it easier, short, and fun now? This is where the saying 'never judge a book by it's cover' comes in handy.

Wiring from dpfi to mpfi for the first time would have taken you 2 hours tops, along with giving your brain some food. It's obvious it's starving. Now you went and gave yourself 50x's more work that's gonna take 100x's the time it would have taken you if you would have just spent that much more time searching and quit being lazy.
