im running 550cc and not sure what it is. i blew my ls vtec turbo motor and going na. i sold 550cc and not sure what rc 310cc to get for my high compression na built. Which is better peak or saturated. Do I get obd 1 or obd 2. My ek is obd 2 with obd 1 converted p28 ecu.

 

Saturated OBD-2

I am taking it that you are not running a resistor box? If you are (but it sounds like you dont know) then you will need Peak and Hold

 

peak & hold injectors you run a RESISTOR BOX and you don't need a RESISTOR BOX for saturated injectors

 

peak & hold is better

 

For All-Motor Saturated is just fine.

Peak and Hold are cheaper, and are better when you start to run a larger injector like 1000cc and higher.

I wouldnt go as far as saying that a 310cc Peak and Hold is better than a 310cc Saturated though

 

im not running a resistor box with rc 550cc on my turbo setup. So am I running saturated obd2?

You have 550cc saturated injectors OBD1 which do not need a resistor box.

 

The only difference is peak and hold is low resistence and Saturated is high. There is no good and better between the two. The amount of CC's is what makes the difference...just make sure that your fuel management can support Peak and hold injectors or you will need the resistor box.

 

how do i know im obd1 1 rc's not obd 2?

 

I don't believe there are OBD-2 injectors, just OBD-1.

Somebody correct me if I'm wrong.

 

Most injectors have the OBD 1 <U>style</U> plug. You need to worry about it being peak and hold or Saturated.

I was about to make the same comment. Peak and Hold isn't any better than saturated. What is better is the injector driver circuit in your ECU. All Hondas (to my knowledge) are saturated driver circuits, which is why you need resistor boxes to drive peak & hold injectors. Typically a driver circuit that can handle low impedance injectors can switch faster, that's it.
