7-Speed DCT - Custom Options

Customization Module 7-Speed DCT

xHP features a “Customization Module”, which allows users to change certain settings before flashing an OTS or Custom - Map. The Module injects those user-defined values into every Map before flash. Usage is simple: Just do your settings, save them and flash any map to apply them.

The 7-Speed is a very different transmission, compared to the 6 and 8-Speed units. Its manufactured by Getrag and basically consists of two manual transmissions in parallel, with one clutch each. A Gear Change is done by pre-selecting the Target Gear in the adjacent Transmission and then opening/closing both clutches at the same time. While one clutch opens, the other one closes at the same time and therefore enables the transmission to carry out “seamless” shifts. BMW used it for around 10 years, mostly in M-Cars and some of the sportier AG Cars, like the 335is E92 and Z4 sDrive 35i. While its raw up-shift performance is unparalleled, it has its drawbacks regarding daily driving, compared to the 6 and 8-Speed Torque Converter transmissions. For instance, spontaneous downshifts over multiple gears in a cruising situation are much quicker on 6HP and 8HP and also maneuvering in tight spaces is much easier with the ZF units. Last but not least, the DCT is much harder to adapt to different power levels and requires more setup work, when mated to different engines.

You must flash your vehicle after changing settings. Just being connected to the car is not enough. You can access the Module through the “Flash Settings” button at the bottom of the Map-Flash Screen. Please note, that the Module is not available for all vehicles and/or engine/transmission combinations.

To see what your specific car can support, please connect the app to your car and click on it. Then in the lower right corner, click on the blue “flash” icon and then on the gear symbol.
Now you can see, what features your car supports.

This can be done without acquiring a license.

Launch Control Setup

You can fully configure the Launch Control Function of your DCT Transmission with xHP. xHP offers to change the Launch RPM, as well as advanced settings for controlling Engine Torque and allowed Slip during acceleration. The stock values are setup for a stock car. Especially for heavily modded cars with sticky tires, big turbos etc. those values need to be adjusted upwards/downwards for optimal acceleration.

Non-M cars (335i, Z4 etc.) use a simpler form of Launch Control. Those cars can only adjust the Launch RPM. Controlling engine torque and slip values through the DCT transmission is not possible on those cars, as they use the normal DTC function to control the Launch instead. (which resides in the Stability Control of your car, not in the DCT)





  • Min: The minimum RPM you can adjust your Launch RPM in-car through the Cruise-Control Up/Down buttons.

  • Base: The initial RPM the Launch Control targets when activating.

  • Max: The maximum RPM you can adjust your Launch RPM in-car through the Cruise-Control Up/Down buttons.

  • Desired Slip at Rear-Wheels (DS): In a nutshell, this slider means more or less spinning wheels during Launch. Move it to the right for more wheel spin, move it to the left for less wheel-spin. The desired Slip is the main variable the Launch Control uses to regulate engine torque and clutch torque during Launch. The DCT calculates the actual slip during Launch through reading the front/back wheel speed sensors around 30 times per second and adjusts engine torque and clutch slip to achieve the pre-programmed values. The optimal slip depends on many factors like climate, tyres, road surface, suspensions setup etc. BMW did setup this for a stock car on an “average” road surface. As a rule of thumb on damp roads or in cold climate (Winter) lowering slip values will get you better times likely. Vice-Versa grippy surfaces (e.g. Drag-Strip or new country-road) and tyres can generate more traction with higher slip values.

  • Torque Initial Slip-Phase (TI): This slider lets you adjust the initial torque when the LC dumps the clutch. It affects how aggressively the clutch is dumped and how much boost your engine is targeting in the first moments. This phase is crucial for a good Launch is it loads up the drivetrain, settles the cars springs and gets the tyres spinning. Right after the LC will start to regulate based on the “Desired Slip”. Too much torque will just burn rubber and the LC needs to adjust a lot downwards in the first ~ 1.5 seconds. Too low will make a weak Launch overall.

  • Torque after Slip-Phase (TAS): This settings adjusts the second part of the Launch, approx. 1.5 - 2.5 seconds after take-off when second gear is engaged. The shift from 1st to 2nd can unsettle the car. Too much torque will lead to instant wheel spin on 1-2 shift (which the LC then needs to tackle again based on the “Desired Slip”), too low values will waste time when pulling in 2nd Gear as the engine may not target full boost instant, even if the traction was available to put all power to the Ground.


SETUP-HINTS: Make sensible changes and do so in small increments. “Maxxing all out” is not the way to go. (unless you intentionally just want to burn rubber). If you are on the Drag-Strip on a warm day, start with a 15% raise for DS, and around 7% for TI . The TI-Slider usually only needs small changes.

The TAS can be adjusted with bolder increments as the car is already loaded when this setting kicks in and it will generate similar traction within a broader slip-window. Be prepared for wheel slip and car going sideways when raising.

The typical FBO car with Stage 2 engine mapping should be fine with the settings stored in our OTS Maps. Depending on traction available it even may profit from a few ticks to the left on the TAS Slider.

If you lowered your M-Car to the max and run 21” Inch tyres it may look cool but traction will be horrible. So lowering all Sliders by a few percent will get you better times likely.

Please don’t ask us, what the “optimal” settings are. If there was an optimal setting, it would be programmed into the OTS Map already. If you want to achieve better times, you need to change, measure, change, measure and so on.

Of course Launch Control gives your clutches a beating. Doing Launch Control 50 times comes with a price-tag on it, no matter if you alter values or not.

The DCT Launch Control can only be used if all of the following requirements are met:

  • 1000m traveled after the last Launch Control launch

  • 60 seconds have past since the last Launch Control launch

  • there is no trailer attached to the car (yes, this gets checked)

  • the parking brake (E-Brake) is not engaged

  • The transmission is not in hot mode: yellow or red

The procedure to activate the Launch Control is the same as with Stock vehicles.

Torque Punch

With this option users can configure the amount of torque that is added on each shift in “Sport/Sport+” and “DSC OFF” mode (AG Cars) and S2/S3/M2/M3/DSC OFF (M-Cars) respectively.

During an up-shift the transmission sends a request to the engine to briefly cut power to ease up the shift. The time-frame for this around 100 - 200 msec. Depending on the amount of torque pulled in this short time-period, the transmission calculates the pressure the clutches need, to carry out the shift. With the “Torque Punch” setting you can apply a factor to this calculated pressure to create a more agressive (or a more tame) shift. The “Punch” can be felt in car as small pull forward during the shift.

Slider to the right means harder shift!

Slider to the left means softer shift!

This custom option interacts directly with option “Torque Reduction”. (see below)

Torque Reduction

During each shift the transmissions orders the engine to cut power, while the transmission is pulling down to the Target-RPM for the next gear. The amount of torque reduction has to correlate with the clutch timing and torque at the clutches to create a quick, consistent and reliable shift, within the clutch specifications.

On high power cars, the DCT often suffers from “spongy” and delayed shifts, which are a direct effect of de-calibrated torque models inside the DME and unadjusted transmission mapping. The DCT is very picky and not that flexible in terms of self-adjustment and may need further adjustment through options “Torque Punch” and “Torque Reduction”, depending on your engine mods. If your Tuner asks how to “adjust for xHP”, just tell him to leave the Load-2-Torque Calculation as close to real-world as possible.

Slider to the right means “more reduction” → The transmissions pulls out more power during shift.

Slider to the left means “less reduction” → The transmission pulls less power during a shift.

Setup hints: A proper shift needs things to be in balance. Just lowering down torque reduction as much as possible is not a general recipe. If you feel the infamous “spongy” shifts, try to raise torque reduction (pull more torque during shift) and raise Torque Punch at the same time. Do this gradually, as when overdone you get the opposite effect. Please do not ask us “what is the best setting”. If there was one, we would have done the OTS Maps already that way.

Use Stock Shiftmaps

Our OTS Maps often sport adjusted Shift-Points in the various modes. If you do like the stock Shift- Points better, just activate this option.

Max. RPM

The AG-Cars (335i, Z4) have different Target-RPMs for D, S and M-Mode when applying full throttle. Instead of shifting at a certain vehicle speed, the transmission shifts at a fixed RPM per gear. With this option you can adjust that RPM target for each mode and each gear. Please note, that the transmission adds some pre-calculation, so it still may shift a bit earlier, then setup in this panel. For instance, when wheel-spin occurs, or you accelerate down a hill. M-Cars only have one automatic mode and therefore only a setting for D-Mode. (Called S in M-cars)

Rear-Axle Ratio

Gear-Change and Throttle-Blip calculation of the DCT needs to precisly know all Ratios in the Driveline. If they are not setup correctly, all target RPM calculations are offsetted, which leads to spongy shifting and incorrect blipping on downshifts. Adjust this option ONLY if you have fitted a different Rear- Differential. NEVER change this on a stock vehicle.

Shiftmap Editor with Presets

The shift map editor enables you to change all shift points in D and S mode to your personal liking. For instance you can make your car shift later from 1st to 2nd Gear when accelerating, or vice versa. Or make it hold 8th Gear for longer on the Highway when accelerating. For an easy start, xHP offers 4 presets: Relaxed, Relaxed+, Sportive and Sportive+.

Those presets make it easy to do a quick test on your car and experience the changes. Just select a preset and flash any map again. xHP will automatically apply the Presets to your Shiftmap during the Flash. Presets work with your Stock Calibration, with all OTS Maps and with Custom Files flashed.

Relaxed and Relaxed+: Your car will shift earlier up and will be less eager to downshift when pressing the throttle.

Sportive and Sportive+: Your car will shift up later and will stay for longer in lower gears. It will also react more quickly to throttle inputs and will be more happy to shift down.

Shiftmap Editor: Editing Presets

For further tailoring, you can also edit any of the Presets, and save your changes in up to three custom slots. Just select a Preset from the Dropdown and click the Toolbox Icon next to it. This will load the Preset into the Editor and expose the stored settings. You can now edit each individual up and downshift and afterwards store your Changes to 1 of 3 custom slots. The Presets itself will stay untouched, so you can always revert to them. Your personal slots also get exported when using the Import/Export feature, so you can easily share them with other users!

Shiftmap Editor: Setup hints

The shift map editor enables you to change all shift points in D and S mode to your personal likings. A “shift map” consists of 12 lines, which are spread over throttle input. Six for upshifting (1-2-3-4-5-6-7) and six for downshifting. (7-6-5-4-3-2-1) Up- and downshifts can be independently configured. The setting made in the editor are always relative to the flashed map. You do not set exact shift points, but rather are able to change the shifting of a given OTS or custom map! The spread is from +50% to - 50% for each shift. For example, if your 5-6 shift on low loads normally occurs at 50 mph, but you want it not to happen before 55 mph, pull the 5->6 slider to + 10%. Same goes for the downshifts. If your trans normally downshifts on 40 mph from 6->5 during coasting, but you want that to happen at 50 mph, pull the slider for 6->5 up to +25%.

Be sure to make sensible changes. If you alter the 1-2 shift upwards, you should do the same gradually to the subsequent shifts, to get a “natural” shift-feel during driving. Rule of thumb is to make bigger changes on the lower gears, and smaller changes on the upper gears. However, you are free to experiment with these settings. xHP pre-calculates and validates all changes against every OTS Map stored on the device. A fixed ruleset gets applied to auto-correct "wrong" settings and prevent dead-locks. Such a dead-lock could happen if your 2-3 upshift-point would be set below the 3-2 downshift-point, or if an upshift would lead to a target RPM below idle- speed of the engine.

Below is an example how to turn the standard Stage-3 Map of a 335i in D-Mode into a very comfortably and low shifting Map:


  • 1->2: - 24%

  • 2->3: - 20%

  • 3->4: - 16%

  • 4->5: - 12%

  • 5->6: - 8%

  • 6->7: - 4%


  • 2->1: 0% 

  • 3->2: 0% 

  • 4->3: - 2% 

  • 5->4: - 2% 

  • 6->5: - 2%

  • 7->6: - 2%

This is just an example, but users are encouraged to experiment and find their own personal best shift map. The Shift point Editor lets you change the character of a given map very much, by just pulling a few sliders.

Enable/Disable Creep

Choose whether your vehicle starts moving/creeping by just releasing the brake, or only when touching the throttle. “Standard” means the flashed file will not get changed. “Enable” let’s the car creep when releasing the brake, “Disable” means the vehicle will only move, when throttle is applied.

Kickdown – Launch

For E-Series - 135i / 335i / Z4

You can select whether to use a performance-oriented take-off behavior when going full-throttle (incl. Kickdown) or if "Burnout-Mode" shall be activated.

In Burnout-Mode the clutch will kick in very aggressively, to immediately spin the rear-wheels.

In Performance-Mode the clutch will be applied gradually to build traction. In both modes you can choose the RPM, where the clutch gets engaged.

This function can only be applied together with our OTS Maps. It will not affect behavior on the Stock-Map! To use this function, please set DSC fully OFF, otherwise the Traction Control will kick in.

When Kickdown-Launch gets activated, it is always active, when DSC is OFF and the car is not using the Launch Control feature.
This way you can use “Burnout-Mode” at the drag strip to heat up the tires and then activate “Launch control”, for example.

For F-Series - M-Cars

The DCT has 2 modes of clutch-engagement when going Full Throttle/Kickdown at standstill, which are based on the current state the DSC (Stability Control) is in. The stock setup is as follows on all F8x M-Cars:

In DSC ON mode the clutch engages gradually at around 1000 RPM.

In DSC OFF it snaps around 2800 RPM. Depending on your personal setup and traction available you may want to change the RPM where the clutch starts to engage in each of the modes. For instance, higher Traction (sticky track, Slicks) means higher RPM possible/necessary before braking traction. Also, cars with upgraded Turbos can profit from raising the engagement-RPM.

Those Launch Modes are NOT related to Launch Control, which can be setup in the "Launch Control" Panel in xHP.

If you used Tools like MHD/bootmod3/MG-Flasher to deactivate Kickdown those modes (and Launch Control) do not work anymore. Kickdown needs to be turned ON in the DME

When Kickdown-Launch gets activated, it is always active, when DSC is OFF and the car is not using the Launch Control feature.
This way you can use “Burnout-Mode” at the drag strip to heat up the tires and then activate “Launch control”, for example.

Take Off in 2nd Gear as Standard

This option lets you choose, wether the transmission uses first or second gear for take off from standstill. This function is not active in the following situations:

  • Only active in D-DriveLogic 1

  • The transmission will revert immediately to 1st gear when activating Kickdown (Emergency Function)

  • During cold start on some vehicles

  • On inclines

  • When transmission is overheated


•limits your vehicles power to approx. 100 HP in lower gears, 130 HP in higher gears

•limits max. RPM to 2500-3000 approx.(depending on vehicle)

•disables Kickdown

•inhibits too early downshifting in Manual mode (max. 2500 RPM)

•locks down the transmission in its slowest operating mode

•inhibits Launch Control/Brake-Boosting.

Safely lend your high-power vehicle to your kids or make sure the shop mechanic does not show-off with your car to his buddies. Valet-Mode can be applied to any map and works safely in all driving environments.


The Stop-Go function makes the transmission stay in 2nd Gear at standstill when a traffic-jam situation is recognized. It's a comfort function to avoid continuous cycling between 1st and 2nd Gear in "Stop-Go" situations. Users can choose to turn this function ON or turn it OFF completely.

Stop-Go: OFF ignores the traffic jam recognition and leaves the transmission cycling between 1st and 2nd gear.

Stop-Go: ON does not mean the transmission will use 2nd Gear always at standstill. This is just when the vehicle senses a traffic-jam-like driving situation. If you want to use 2nd Gear as Standard for take-off, please use the respective Custom-Function.
