Tuned BIN · Mercedes-Benz
From Redline Autohaus & Performance
The company profile has been reviewed. This does not assess file safety, ECU compatibility or government identity.Uploader’s title: Tuned / modified · Mercedes Benz CLS550
Uploaded as Mercedes Benz CLS550. The current research associates this file with Mercedes-Benz. Review candidate alternatives in the vehicle details.
Candidate means a possible identity that the analysis could not establish confidently. Full findings are available below.
Inside the tune
What changed.
Observed calibration changes in this accepted file. Expand an observation for the analysis and any uncertainty.
01Broad ignition timing advances
Observed selected load-and-speed cells across related ignition surfaces advanced by approximately 0.75–3.75 deg while axes and overall contours remained unchanged.
02Raised load and torque calibration
Observed upper cells in complementary load-to-torque and torque-to-load conversions increased coherently. A maximum relative-load curve also rose by about 20% while retaining its original shape.
03Maximum load curve set near its scale ceiling
Observed all eight points of a maximum-load curve change from approximately 50–87% to 99.61%. This is consistent with a deliberate ceiling-level limiter calibration, although runtime behavior was not tested.
04Mixture-protection targets were raised
Observed rich protection targets increase toward 0.867–0.875 lambda, while a loaded target surface was reshaped to include 0.875 and 0.922 lambda regions.
05Engine-speed ceilings increased and flattened
Observed multiple 6,500 rpm limits raised to 6,700 rpm, indexed 5,500/6,500 rpm limits flattened to 6,700 rpm, and one distinct 4,000 rpm ceiling raised to 6,700 rpm.
06Vehicle-speed ceilings raised uniformly
Observed indexed vehicle-speed limits originally spanning 160–250 km/h changed uniformly to 300 km/h.
07Ambiguous percentage curve flattened near maximum
Observed an unidentified descending 100–50% curve become a uniform 99.998%. Its exact control purpose remains unresolved, so the operational meaning of this change is uncertain.
