YOUR TRANSMISSION.
YOUR SETUP.
YOUR CUSTOM MAP.
Take your transmission tuning beyond an off-the-shelf calibration.
The xHP Custom Map Service delivers a personalised TCU (Transmission Control Unit) tune developed around your vehicle, modifications and driving goals.
Sharper performance shifts. Refined shift behaviour. Personalised transmission response. A calibration designed for your unique setup.
Unlock the Next Level of Transmission Tuning
Engine performance is only part of the driving experience. Your transmission determines how that performance reaches the road.
xHP has transformed automatic transmission tuning by making advanced transmission calibration accessible through its Flashtool platform.
While standard xHP tuning stages deliver predefined performance characteristics, a Custom Map takes personalisation further.
Every performance build is different. Engine output, drivetrain modifications, transmission hardware and driving preferences all influence the ideal calibration.
The xHP Custom Map Service gives you the opportunity to move beyond a standard tuning package and develop a calibration tailored to your individual requirements.
Instead of adapting your driving expectations to a predefined map, a custom calibration is developed around your performance priorities.
What Can a Custom xHP Map Deliver?
Custom transmission mapping enables a wide range of calibration adjustments, with available features determined by the transmission platform and software configuration.
Optimised Shift Strategy
Tailored shift points and gear-change strategies designed around the engine's performance characteristics and intended use.
Enhanced Shift Response
Fine-tuned shift behaviour to achieve the desired balance between responsiveness, performance and refinement.
Torque Converter Calibration
Customised torque-converter lockup characteristics for supported automatic transmission applications.
Modified Transmission Setups
Calibration development for specialist configurations, including supported upgraded transmission components and hardware.
Personalised Driving Characteristics
Selected shift patterns, downshift behaviour and driving-mode characteristics can be tailored to individual preferences.
Performance & Everyday Refinement
Custom mapping can prioritise aggressive performance characteristics, smoother daily driving or a carefully balanced combination.
Standard xHP Map vs Custom xHP Map
Both options use the powerful xHP transmission tuning platform. The difference is the level of personalisation.
| Feature | Standard Map | Custom Map |
|---|---|---|
| Calibration | Predefined | Personally developed |
| Vehicle-Specific Goals | General tuning stages | Individual objectives |
| Shift Strategy | Preset characteristics | Tailored adjustments |
| Modified Hardware | Standard map parameters | Specialist calibration options |
| Personal Revisions | Not included as a bespoke service | Up to 5 revisions |
| Tuning Approach | Ready-made map | Individual engineering service |
Customisation capabilities depend on the transmission and available calibration parameters. A custom map does not automatically guarantee higher performance than every standard map.
What's Included in the Custom Map Service?
A specialist transmission calibration service developed by xAutomotive's mapping engineers.
-
Individual TCU Custom Mapping
A personalised transmission calibration based on your vehicle configuration and tuning goals. -
Specialist Calibration Development
Individual engineering work to develop transmission characteristics around agreed requirements. -
Adaptation Data Assessment
Review of relevant transmission adaptation information where appropriate data is available. -
Up to Five Custom Map Revisions
Refinements to the calibration within the scope of the custom mapping project. -
Personalised Driving Characteristics
Selected supported transmission settings tailored to the desired driving experience.
The real value of the Custom Map Service comes from individual calibration work, rather than simply selecting a predefined collection of tuning settings.
Transmission Tuning Applications
The xHP Custom Map Service offers options for several popular BMW and Toyota Supra transmission platforms.
6-Speed Automatic
Custom transmission calibration for supported BMW ZF 6HP applications.
8-Speed F Chassis

The Custom Mapping Process
Every custom calibration follows an individual development process, from initial vehicle information through to calibration refinement.
Vehicle & Setup Information
The mapping project begins with the vehicle's transmission configuration, modifications and desired driving characteristics.
Calibration Planning
The engineering approach is developed around the intended application and agreed transmission tuning objectives.
Custom Map Development
xAutomotive's mapping engineers develop the personalised transmission calibration.
Refinement & Finalisation
The custom calibration can be refined through the included revision process to meet the agreed tuning objectives.
Frequently Asked Questions
What makes a Custom Map different from a standard xHP Stage 1, 2 or 3 map?
Standard xHP maps offer predefined transmission calibrations designed for general tuning requirements. A Custom Map is developed around an individual vehicle configuration and specific tuning objectives, offering greater scope for personalisation.
Is custom mapping only for highly modified cars?
No. Custom mapping can be relevant to different types of vehicle builds, including performance projects and vehicles where specific driving characteristics are desired. The calibration is developed according to the individual project requirements.
Can a custom map improve shift behaviour?
Yes. Shift characteristics are a key area of transmission calibration. Depending on available software parameters, custom mapping can refine selected shift points, response and behaviour to suit the tuning objectives.
Can features from different xHP stages be combined?
In supported applications, selected features from different standard xHP tuning stages may be combined as part of the custom calibration process.
How many revisions are included?
The service includes up to five custom map revisions within the agreed tuning scope. This allows the calibration to be refined during the development process.
Is the xHP Flashtool licence included?
No. The xHP Flashtool licence is sold separately. The Custom Map Service covers specialist calibration development rather than the software flashing licence.
Does a Custom Map guarantee faster acceleration?
Performance results depend on the vehicle, drivetrain configuration, modifications and calibration objectives. A Custom Map allows more individualised transmission tuning, but specific acceleration improvements are not guaranteed.
Is this a physical product?
No. This is a digital transmission tuning service. The product consists of specialist calibration development and the included revision service.
