HKS FCD wiring on YRV Turbo

Forum: 

Hi everyone!
I have YRV with a home made air filter and a blitz-nur spec exhaust.

As many have said, I expected to have some fuel cuts.
Indeed I have some big fuel cuts under hard acceleration and especially around 3000rpm.
So I've installed a HKS FCD to the pressure sensor, connected to the red wire (PIM signal).
Exactly like this :

Now, whatever the FCD setting (6,7,8,9,10,11,12...), I still have fuel cuts (less when set to "11" but fuel cuts yet).

So can you confirm or describe the connection of the FCD on the pressure sensor please?
Am I good with the central RED wire of the pressure sensor?

Many thanks.
