Sakimano. I nickname the corporate guys at Quattro (or as you may please, Inc) as the german GmbH guys (Norweigan AS, Swedish AB). Pardon the confusion.
By powdercoating the S/C radiator black, you lose cooling efficiency(per TTS). Hence, I was adviced not to opt for the blacked out option when I purchased the S/C system. However, perhaps I have been proven wrong? bitcpy on AZ has provided some very interesting option to the “getto” look while improving the cooling effeciency further. Here is a link provided. (http://www.calicocoatings.com) I might have to try this?
In regards to the EPC situation and the cut off. The reading was “Fuel pressure TOO HIGH??” I never though I would need to give the RS4 blood pressure meds? We believe the combination of the very high temp/humidity is S FL with slightly lower quality fuel than 98 RON might have given the ECU’s a tilt? We are now running a mix of 93oct and 105oct, plus,nwe are finally cooling down in S FL.
We have not finished the ECU programming yet. As of today, she is running at 95% on the MRC tune. We are ripping out the ECU chips in a couple of weeks and I will report back in.
Happy Holidays all.
Over and out for now.
