Default Re: Hfs-4 wiring for Audi B8 s4 3.0 (2009-2013)?

So it looks like I was able to smooth out the timing pull but by turning P/I-R to the 1 o'clock position and adjusting thres and gain accordingly. However, I am wondering if I have an issue of where I tapped boost from, as I started seeing the unreliable behavior when using MPS and had the P/I-R knob set below the 12 position. If I set it to the 10-11 position, I would only see spray seldomly and sporadically. Setting thres too low and I was seeing spray at idle!

I think for my use of boosting octane primarily then providing cooling secondary, it is probably okay for me to use engine load as the ramp mechanism.
