I ordered some high impendance 720cc injectors online (I have RTek v1.8) I received them and they were brown, offset, and high impendance. I know my engine is a S4 engine. I have an N332 ECU. Is the N332 the 87 ECU, and the N333 is the 88 ECU? So, if the N332 is the 87 turbo model ECU... then shouldn't I get low impendance instead? or does the impendance matter to the ECU?

I checked out the FAQ and found this:

Year Engine Plug Size Colour Part #
84-85 13B NA, low square center, 680cc, orange, 195500-0900
86-87 13B NA, low square center, 460cc, red, 195500-1350
86-87 13B Turbo, low square center, 550cc, tan, 195500-1370
88 13B NA, high square offset, 460cc, purple, 195500-1350
88 13B Turbo, high square offset, 550cc, purple, 195500-1370
89-91 13B NA, high oval center, 460cc, red, 195500-2010
89-91 13B Turbo, high oval center, 550cc, purple, 195500-2020

Those are what came with it.

 

The ECU doesn't know high vs low impedance because the harness takes care of that issue.

If you are using high impedance then no resistors are needed.

If you use low impedance then 6ohm by 10watt resistors are needed at the least(I'm currently using 6.8ohmx10watt resistors on my secondaries).

 

So, these will work... thanks!
