Hi a-dandy-scot, here is my recollection from summer 2018:
The installation went smoothly. No issue with the fuel gauge. I removed the stock controller altogether, though. I had a short blast over my home hill, B-road, 30 km, swiss style. Just a short report of this quick test before I do a more extended evaluation on the German Autobahn:
1. The car feels sorta softer right away when leaving my car park.
2. The typical “pogo” is gone.
3. Less diving while accellerating or sharp braking.
4. Very composed when booting it in 2nd to 60 mph.
5. Less roll in corners.
6. Transmits much more steering confidence in long corners with higher speed than before.
I am a daily driver with no track racing. The first verdict thus is: very well invested money. A clear improvement, towards an Audi but still a genuine Focus RS.
I tried all 4 modes.
Normal: slightly softer ride, but paradoxical pogo-effect on some flat-like-pool-table roads. So no real option for my daily commute into town, but for motorways it’s fine.
Sport: a bit stiffer than before but improved steering.
Track: just bloody f***ing brilliant!!! On B-roads it’s a very big improvement and so confident!
Drift: a bit harder and more composed in quick corners. Daily commute as before.
HTH, drive safe 😎
