P28 ecm for mpfi conversion on d15?

[dan89]

I've got a few things I needed to get done to my car finished up and now the next thing on my list (after wheel studs) is a mpfi conversion.... what I'm wondering is if I can run the vtec p28 ecm for a d16z6 on my non vtec d15b2 as long as i have the dizzy, sensors, etc. I plan on dropping a z6 in here once i have the cash set aside and the time to do it...

Any help appreciated

You would have to do a obd0-obd1 conversion and it would probably throw codes if its a stock ECM because your engine won't have everything it needs...like VTEC.

[FrodoGT]

He said it. Itll throw vtec solenoid codes. If you want to go obd1, and not change the head. Use a p06. Its the non vtec d15b7 ecu.

[Christ]

If you just swap the ECU, you'll have injector codes, and your engine most likely won't start.... you can use a Vtec ECU on a non-Vtec engine, but you'll throw a Vtec solenoid inactive code whenever it should engage.

Best bet is to get a PM6 and do the MPFI swap, then invest in whatever you want and sell your other parts when you're ready.

[FrodoGT]

Actually on an obd1 ecu itll throw the code without ever trying to hit vtec. It just knows...

[Christ]

yeah, solenoid inactive code.. can't think of what it is... I've never had it happen until WOT tho.

alright thanks guys, now what i'm wondering is if i could put a z6 head on a d15 block...

[Tony]

Its called a Mini-me, do a search for it

[dan89]

The only thing I found was a z6 head on a d16 block

[Tony]

I'm pretty sure its the same on a d15 block. Give me a little time and I will find out. I frequent lots of boards, d-series.org is a good place for engine info

[Christ]

It's precisely the same, except depending on what block you use, you might need to switch to pistons with 4 valve reliefs (B8 I believe)

You also could have to either remove or drill out the oil thingy (technical term) that goes under the head in the oil passage.. it's a little removable metal thing... not sure what it's called atm.

But, it acts as sort of a Metering Device so that you're keeping oil pressure, and not flooding the head with oil... which, if you're at all familiar with D-series engines, isn't a problem at all...

[dan89]

well the block i'm gonna use is a good ol' d15b2

[dan89]

just got a mpfi intake on ebay

[Tony]

Found a d15b7 mini me swap:

There are other useful things in there also. The d15 mini-me write up might not be exactly what all you need to do. I haven't went and read it all yet. I had actually found 2, the first one was just retarded, so i won't give you the link for it, lol.

[dan89]

lol thanks tony, as i said above i jus bought a z6 intake manifold, now i'll be off to the junkyard in the coming weeks for the tb, fuel rail, etc.

and hopefully find a PM6 ecm to go mpfi
