2003-2007 Mercedes-Benz SL55 AMG M113K Mk-Ultra Calibrated TCU

2003-2007 Mercedes SL55 Amg Custom Tuned TCU software.

Torque Limiters Raised.

Torque Management Overhauled

Pressure Control Calibrations Overhauled

Many other features are calibrated.

3 Different Tune Types:

Shift Speed+ is for the guys who don’t wanna feel shifts and want street cruisers. At wide-open throttle, shifts become faster but not firm like stage 1. Includes torque management overhaul to minimize bogs/power dips during around-town shifts. Torque Limits were raised also. Agility Mode Included for sprinted driving and no gearbox live for the moment learning.

Stage 1 Street Tune gives faster around town/street nice shifts depending on the load of the engine. Wot Fast crispt shifts. Torque Management Overhauled. No bogs/dips in power during shifts. Torque Limiters Raised. Agility Mode Included and Modified for faster firmer shifts. No gearbox learning with A mode.

NEW: SL-55 SLR Hybrid Version.  Mandatory to have Blue-Top Solenoids! If you do not know if you have them do not order.  The newest update 3-20-23 completely changes how the car drives with 45% faster shifts that are not harsh or slam but give a nice smooth shift feel, gearbox learning radically changed, engine torque management smoother power flow, tcc lockup no longer lugging.

 SLR BLACK SERIES 

After 6 months of development, testing, modeling and data logging our new release is a game changer, bringing major changes to drivability and shift performance and feel, unlike any release we have put out.

• The Torque Converter logic has been changed to significantly reduce the common 5g clunky transmission when shift speeds are sped up, smoother transition of lockup clutch and absorbing torsional vibration of the engine and
  powertrain, and smoothing out the engine rotation. Changes to Reverse flow mode and Forward flow mode reduced/eliminated a lot of tcc lockup bugs.

• 3-4 trailing throttle clunky bumps were reduced significantly/eliminated with ecu tunes from Race iq and a couple of others.
• Smoother transition into gear and reverse.
• The newest tcu operating system available 
• Torque management has been recalculated for better torque control during driving and shifts.
• Full control M-mode holds gears. (Only in M-mode you toggle to with mode button)
• Drive modes included are C-Comfort Mode. S-Sport/Standard Mode. M-Manual Mode. A- Abuse/Agility Mode.
• Torque converter control is radically different, with smooth coasting to stop and smooth parking lot driving without jerking from stock tcc calibrations that most hate.
• More sensitive downshift per throttle %
• WOT downshifts are faster into lower gear. These transmissions do not skip gears they are sequential type so going from 4-2 downshift has to downshift to 3rd then 2nd. We sped that up significantly.
• Blue-top solenoids are MANDATORY
