Mini Cooper HFS-3v3.1 help.

[narvarr]

I bought an HFS-3 v3.1 system second hand from a guy with Porsche. He never installed the system so it's still new in the box. I've been looking over the manual and it seem there is a soldering modification that needs to be done in order for the system to work properly on my car. Can anyone confirm if this is correct on the diagram?

I have checked my circuit board and it is not soldered between link 1 & 2 for the single jet application.

I believe the 3.1 has jumper link instead of soldering links for changing iDC scaler.
But for a single just operation, you need to solder link 2&1. Is this something you can do?

[narvarr]

Yes, it is something I can do. I just needed to be certain that it needed to be done for my application. Thank you.

for one jet, you need to do it.
