CC 3.6 FSI — Stage 1 ECU Tune

This one is a story about listening to the engine. Through development the VR6's knock feedback kept stepping in earlier than a healthy 3.6 on proper 98 RON should — the classic signature of fuel that isn't what the sticker on the pump promised, or of a tank that had been topped up with something lesser. Rather than lean on the timing and fight the sensors, the calibration was shaped to what the engine would genuinely hold: a clean +9.3 kW and about +20 Nm through the middle of the range, delivered without a single degree the engine had to pull back.

That mid-range is where this car lives on the road — the curve now sits flat around 260-plus Newton metres from 3,000 rpm to past 5,000 rpm, so the CC responds the moment the driver asks instead of waiting for revs. And the honest professional read: there is more in this engine. With verified genuine 98 RON in the tank, the knock margin that held this calibration back opens up, and a follow-up session can push the same safe, data-led process further. The dyno sheet's baseline printout also shows why curves beat single numbers — its 'peak torque' was a roll-on transient at 1,900 rpm that both runs share; the real story is the sustained curve, and that's what's recorded here.
