Experience sharper, smarter shifting with RacingLine OEM+ TCU software, professionally installed in house at JCR (Leeds) Ltd, as an authorised OEM+ Technical Centre for Yorkshire.

Our OEM+ calibration transforms the performance and feel of your DSG or S-tronic gearbox, unlocking the drivability and torque potential your car was built for.

At JCR (Leeds) Ltd, we don’t flash random files or chase numbers. As an authorised RacingLine OEM+ installer, we use genuine software developed by RacingLine’s calibration engineers and fitted by our own trained technicians.

Every installation follows a proven, transparent process, all vehicles are health checked, data-verified, and tuning is tailored to your vehicle’s setup.

We also operate from a dyno ready workshop equipped for pre and post tune testing, ensuring that your gearbox calibration perfectly complements your ECU software and supporting hardware.

RacingLine’s OEM+ TCU software is built using OEM grade development and methodology. Rather than altering a few limits, each gearbox file is a full recalibration, designed from scratch to deliver strong, consistent, and predictable performance.

One installation serves your car from standard to full Stage 3 builds, dynamically adjusting clutch pressure and torque limits in real time to match your engine’s output.

It’s the same engineering philosophy used by vehicle manufacturers, redefined for maximum performance.

Faster, smoother gear changes
Recalibrated shift timing and pressure provide instant, seamless up and downshifts.

Dynamic clutch pressure control
Clutch clamping is continually adjusted to engine torque demands, ensuring zero slip, maximum torque transfer, and longer clutch life.

Raised torque limits

Removes factory torque caps that cause the gearbox to request power reduction from the ECU.

Optimised drive modes

Comfort, Normal, and Sport modes are reprogrammed for more intuitive, natural responses — relaxed when cruising, aggressive when you want it.

True manual mode

No more unwanted auto-upshifts. Full driver control when you select manual shift mode.

Launch control optimisation

Refined launch behaviour and engagement RPM for repeatable, awe inspiring performance.

One-flash compatibility

Your OEM+ TCU file evolves with your vehicle, no need for repurchasing software when you add hardware or move up stages.

Cross tune compatibilityFully compatible with RacingLine ECU software and safe to run alongside other reputable engine calibrations.

1. Pre-tune health check – diagnostics, fluid level check, and visual inspection
   

2. Baseline verification – optional dyno run to record power and gearbox performance
   

3. OEM+ software installation – via OBD or bench, depending on TCU type
   

4. Data verification – post-flash checks to confirm calibration integrity
   

5. Road test and handover – ensuring optimal drivability and shift strategy
   

As part of RacingLine’s global Technical Centre network, every TCU installation we carry out is health checked and verified before tuning.
