? for those who run N20 TMAP and HFS4

A few questions for those of you who are running the HFS4 and the N20 TMAP.

Are you modifying the HFS4 controller as detailed in step #2 in the below image?


What is your preferred settings for PI/R, THRES, GAIN etc?

I am getting some flow issues as of recently, and one of the changes i made was adding an N20 TMAP sensor. Trying to rule some things out...

Thanks for any help you can offer.
