Need help on ecu PLZZ (99-00 civic d15z4)

[mynameisowen]

Ah well no. DPFi means 2 injectors not 4.

Honda attempted to call what we have SFi, from Simplified Fuel injection jada jada.

So:
D15B2 engine, 2 injectors (one main, one helper) = DPFi (Dual ...)
D14A3/A4 engine, 4 injectors squirting in pairs = SFi
D15B7 and alllll the rest, 4 injectors squirting sequential, = MPFi (Multi ...

SPFi (Single... )? No Honda engine I know from the top of my head that fits that description. Probably in the past or on bikes they got them. Btw I think the P comes from Programmable isn't it?

Yes I am being silly. At college we used to call an engine with a single injector upstream "single-point" (similar to DPFI) and ones with individual injectors "multi-point". That's where my confusion with the naming comes from. So ignore what I said and listen to dodo =P

ok say i have the full obd1 engine harness, dizzy an iacv and the ecu could i just swap every thing over instead on cutting wires.?

[Dodo Bizar]

Nope, I'd say use mine.

You'll still have to cut wires, the engine harness cannot be plugged into your car, really different design.

from OBD1 harness u ned only:
4 connectors for Injectors Jets (swap with stock, and unPair it)
1 connector to IAT (swap with stock TA)
2 connector sto DIZZY (new 9-11 wires to ECU)
1 connector to IACV
2 connectors to VTEC system (valve and sensor)

that's all. u dont need put in car all harness OBD1, just swap connectors.

thanks for all the help i have the full engine harness awaiting ecu half behind the firewall what does it connect to i mean the engine harness to the ecu harness behind the fire wall are they separated or joined im asking thing because i got the engine harness complete but it has no ecu connectors?? isnt it a complete haness together, the ecu and the engine harnesses? or is it those both ends have a connector to joint them??

OBD2 engine looms run all the way from the engine directly to the ECU.

OBD1 engine looms run only towards the right tower, from there a second loom passes the firewall beneath the fusebox and enters the ECU.

What I should do is what Ilya says, get the connectors of the loom. But also get a set of ECU connectors from a car of the scrapyard, I usually cut out the ECU connectors with as much wire length as possible, up to 40 cm. That is if you want to convert your current OBD2 loom to OBD1 yourself.

so repin the SFI connectors, use connector b from scrapyard loom, take out connectors from engine harness i have (dizzy and iacv) connect the up an rewire injectors..

ALEXFOS, sorry) u write 4 page. u have DU articles how to do, and realy example how swap ecu and other. what's problem da man? JUST DO IT =)
just start it)
