I just need a quick answer really quick, im about to sell some h22 injectors to someone and they want to know if they are obd1 injectors, does that matter cause I thought it didn't really matter if it was 1 or 2?

 

There is no difference between OBD1 and OBD2 injectors.

EDIT: as far as connectors, sorry for the nonspecificness.

 

On H22 the OBD1 are peak and hold (low impedance) with a 345cc flow rate and OBD2 are saturated (high impedance) with a 290cc flow rate. It makes a difference for both electrical and tuning setups.

If you have a multimeter you can test the impedance but not the flow rate.

Low impedance have a resistance of 2-3 Ohms
High impedance have a resistance of 11-13 Ohms

 

Just to add to what Ghost said, actually the '96 h22a1 engine uses the obd1 type injectors even tho it's otherwise an obd2 engine...this is the only exception to the rule

 

To emphasize what DeadlockRiff said: The F22B1 has a 240cc LI injector with a metal clip style plug while the F23A1 has a 240cc HI injector with a button style plug. Just as an example.

 

Ok the guy I was selling them to never came to pick them up haha but thanks anyways guys this was good info that helped me a lot and now I know the differences between them
