I have an obd2.2 integra ('98+), and would like to run 450cc dsm injectors with my stock ecu (p73).

Can someone please explain what I need to do with a resistor box? Where do I wire it in, and what exactly does it do?

Also, when I switch to an obd1 ecu (hondata p28) in the next couple of weeks... will I need to reconfigure this setup somehow?

I know all of this has to do with saturated and peak/hold... but please break it down for me.

Thanks.

 

Still need help?

 

Yes please!

Contact ef-1 tech support in my sig. He should be able to help you. He has a huge amount of knowledge and is friendly.

 

The reason a resistor box is needed is because the DSM 450's are low impedence injectors that send different voltages and is necessary to run a resistor box.

It's hard to explain while typing, and I have a diagram somewhere, I'll have to look for it.

But basically you take the Yel/Blk wires from the fuel injectors, cut them from the Engine harness, with enough slack from the fuel injector harness themselves.

You wire those Yel/Blk wires to the Resistor box from the fuel injectors, and wire up the 5th wire (depending on what resistor box it is) to the yel/blk wires from the engine harness.

As for the converting to OBD1, no you will not. I would just get the Hondata tuned for your set up and run an OBD2b to OBD1 jumper harness using the P28.

HTH.

 

Good info.


Hey Brandon.

I like your sig.

I think 99Hybrid_Hatch has some good advice on H22/H23 tensioners.

Already talked with him in the Prelude forum

Good info he gave. I need to order me one within the next couple days.

 

.....do you have that diagram anywhere?

The resistor box just has a plug on it.....

BTW: which resistor box should I use (or does it matter)? Any year honda?

DSM injectors use obd2 injector clips, right?

 

ive got a resistor box for you... I can give you both plugs also with some of the wiring harness... let me know

 

Wow, people don't know how to search, this has been covered in depth, one MILLION times :mrevil:
