Alright, the other post about this got me thinking. I have a 95 Z6 in my 91 Hf. It ran with a rpm switch until now, when I am converting to OBD1. My question is do I still need the resistor box for the injectors? If not what do I do with the wires for the injectors?

Thanks guys.

 

Depends ONLY on what injectors you use. If you use the old OBD-0 Injectors you need the resistor box. OBD-1 no resistor box.

If you plan to turbo using DSM Injectors (Peak and Hold) then stay with your old OBD-0 Injectors (also Peak and Hold) = Less work. The OBD-1 Injectors are "Saturated" do a quick search and you'll learn the differences.

 

yup as stated before if you go obd1 you won't need it.

 

just use the same injectors you have now there is now and leave the box in.....there is no performance gained from switching to saturated injectors

I would tend to disagree the obd1 system has its gains.

Powerwise stock for stock no but I much rather deal with obd1 to tune as would most others.

Getting parts is also simpler.

 

Since I am going OBD1 I will need the OBD1 injectors and to get rid of the resistor box. But can I run OBD1 with the injectors from OBD0 w/ the box?

If you use OBD0 peak and hold injectors, you need to run the resistor box.

If you run OBD1 injectors (Like the ones that came with your Z6) you need to remove the reisistor box and solder all the wires at the resistor box together.

It really makes no difference which ones you choose to use. They both function the same. And can be used on any OBD0 through OBD2 systems.

Saturated injectors (Like the ones with your Z6) have internal resistance. The resistance is built into them, thus no need for the external box.

Peak and hold resistors (Like the ones that came off your CRX originally) have no resistance and the box provides this resistance.

Your ECU and distributer does not care which type you use, thus you can use either setup on OBD0, OBD1, or OBD2.

What you cannot do is use resistor type (Saturated) injectors with a resistor box. And you cannot use non-resisted (Peak and hold) injectors without a resistor box. Your resistance for the injectors would be totally fuxxord!

If you plan on going turbo in the future, I would recommend using the old injectors and resistor box. That way you will have less work in the future when you add the aftermarket injectors for your turbo setup.

If not, just keep the injectors that are in the Z6 and solder all the wires together at the plug on the resistor box to eliminate that fromt he circuit.

I think rywire also sells a nice little plug that you can attach to the green resistor pack plug that connects all the wires for you. That way you dont need to do any soldering, and re-converting back to peak and hold resistors only takes seconds.

 

Awesome, that is exactly what I wanted to know.

 

No problem man. That's what makes HT great. Sharing the information from trial and error, and piggy-backing research done from here and other forums.

I am glad I could help and I wish you the best of luck in your project!

 

Thank you.
