I found a reference today that said 2G (black top) DSM 450cc injectors are peak and hold while the 1G (blue top) injectors are saturated. Is this true? Or are they all the same? If they are all the same which is it, peak and hold or saturated?

Also, what OBD connector is on which generation injector?

After wading through all the "DSM 450cc injector" posts I found by searching (it really really sucks that we can only search on post titles) I was unable to find an answer.

 

They are all low impedence designs.

 

low impedence = what? peak and hold since peak and hold is low resistance?

 

yes..

 

so do they all have the same connector? If so, which one is it?

 

Use OBD 0 plugs or the dsm plugs and the OBD 0 or DSM injestor resistor pack.

 

prelude obd1 injector clips and pack works fine... They were a direct drop in with my h22a
