Hey guys and gals, first of all sorry for the repeat on this topic but all i can find are people who have either a SI or a CRX and im not blessed with that option, but screw it! Momma always told me that things in life dont always come easy... so knowing that, here is my setup. Please correct/add anything if needed. Thank you ahead of time

Ok so thats what i got so far. So question is with that conversion harness can i just convert my car to MPFI using the orginal harness for it to work? or will it not be that easy?
Also, ill be using the injectors from the motor as well. I know nothing of this and im in need of some tutoring on how to be able to use them haha.
I think i hit all of my gray areas if anyone could shine some light on this topic or show me a link to read about my situation then that would be great. thanks again.

 

Can you link to the Rywire conversion package you are talking about?
You said 'mpfi' and it's a little confusing.
Your STD is DPFI so you need to go frmo DPFI to MPFI.
Rywire does a harness for this so I just want to double check for you.

Distributor - You may need an OBD2 to OBD1 adapter.

heres the link. Its intended for MPFI EFs only and i was hoping i can just convert my car over to MPFI without having to buy that $350 dollar harness then use the conversion harness without a problem... ahhh hopes and dreams haha

 

For corrections sake it's VTEC... vetch is a phone manufacturer...

It also helps to search as most, if not all, of your answers can be found in our lovely FAQ's...

You can call them to verify, but I don't see that working for you.
You are going to need to do a DPFI to MPFI conversion on your DX harness - totally not worth buying the harness RyWire sells for $$$, but that's my opinion.... unless you are looking for a show quality install.
WHY? Because your DX harness is missing 4 wires (2 wires go to injectors and 2 go to the distributor that your DPFI harness currently does not have). Also, a few of the ECU pins are in different locations between DPFI and MPFI.
THEN you will be able to plug that OBD0 to OBD1 jumper in and all the wires will be going to the right places.

 

No way around it, you will need to do the MPFI conversion. And if I recall, rywire is out if stock on the DPFI to MPFI (obd0) harnesses.


I can build you a completely brand new engine harness with all the wiring pre done for a sohc vtec motor. Completly plug n play.
I'm a lot cheaper. Feel free to txt me for a price quote or check out my sig below for pics of my work.
