2003-2006 Mercedes-Benz E55 AMG M113K Mk-Ultra Calibrated TCU

THIS VERSION IS NOT FOR S55-CL55-SL55 DO NOT ORDER WILL NOT WORK FOR YOUR CAR AND YOUR ORDER WILL BE CANCELED.

2003-2006 Mercedes E55 Amg Custom Tuned TCU Plug And Play.

After hundreds of live testing and simulations and feedback from many other customers, we have done major changes to calibrations to fit most drivers in what they strive for. Fast smooth shifts normal to part throttle, mid to wot firm fast shifts.

Torque limiters raised to 1200nm

Torque management overhauled

TCC Control during shifts recalibrated

Pressure controls and overlaps have been recalibrated

Torque reduction during shifts scaled out for modified cars.

Many other features are calibrated.

3 Different Tune Types:

Speed Shift+ 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 raised also. Agility Mode Included for sprinted driving.

Stage 1 Street Tune (03-20-23 Update to new car shift performance) 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 during normal driving. Torque Limiters Raised. Agility Mode Included and Modified for faster firmer shifts. No gearbox learning with A mode. This has been updated to shift like a new car now.  Blue-top solenoids gives the best results. Most E55 cars have them, 05-06 came stock with them. I can verify through Vin #

Stage 2 Drag/Street racing. —DISCONTINUED 

Blue-Top Solenoids are Mandatory! Does not work with Brown-Top solenoids! You will get wonky shifts

Mercedes-Benz McLaren 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

“Warning” If your tuner has removed the rev limiter or raised too high you could over-rev the engine with Full control M-MODE and float valves or other damage can occur! ECU Rev limiter should never be removed!

*Gear Ratio Option*= Pick STOCK unless you replaced rear differential gearing. TCU does not change the rear gear ratio!  You will go limp mode if the gear ratio is incorrectly chosen or pick the wrong car.

Handling time is 1-3 business days for shipping. Each TCU is flashed and tested before shipment.
