i have a b16 with ctr piston. i just got some h22 injectors with res box. i need to know how to install this. thanks.

bump. i got no answer

i know how to plug in the injectors but what about the res box?

 

need help asap!

doi have to slice some wires to get the res box in? do i even need the res box?

 

i think it fits right on perfectly and there is no need to res box. im not a 100% sure but thats what i heard.

bump for u

 

what year prelude did they come out of? and what engine

 

call rc engineering.. but i think the fifth gen prelude do not require resistor boxes if i remember what rc engineering told me.

97-2001 prelude h22

before that they do

 

easy way to find out: take a multimeter and do a resistance check on the injectors. Are they low or high impedance?

Low impedance: 2-3 ohms(needs resistor box)

High impedance: 12-15 ohms(no need for resistor box)


I think that the OBD-I H22 injectors need a box and the OBD-II injectors do not. Not sure though.

The OBD1s are 340cc and the OBD2s are only 290cc.

Search brought up a shitload of threads. I also read somewhere where you can wire up individual resistors with each injector.. not sure how to though.

yes you can but I am not sure which resistors to use! More than likely 1K ohm or 10K ohm resistors; but find out before using these. Also do measure resistance on a resistor box b/c the resistors are in a parallel network which means total resistance is different and than the individual resistance of each branch or wires!

If you can find out how much current the ECU signal puts out and how much current you need for the injectors, you can mathematically figure it out.

Do some more searching and get back to me. I can give you formulas if you need them.
