Tuning
Custom tuning files developed for professional tuners, workshops and enthusiasts. Upload your original file alongside your requirements and receive your completed tune.
Services we offer
Three core areas of work: ECU calibration, TCU calibration and specialist ECU services. Open a category to see exactly what we can do for you.
ECU Tuning
Custom ECU calibration for standard, modified and bespoke performance vehicles. From software-only solutions and Stage 1 remapping to Stage 2 hardware upgrades and bespoke Stage 3 tuning.
TCU Tuning
Custom TCU calibration for smoother, faster shifts and improved torque handling. From shift-point optimisation and raised torque limits to fully bespoke transmission mapping.
Specialist ECU Services
Specialist software and electronics work beyond performance mapping: immobiliser solutions, ECU cloning and EEPROM work, diagnostic software fixes and bespoke one-off requests.
How remote tuning works
Four simple steps from upload to validated tune.
Upload your read file
Read your ECU or TCU with your preferred tool, then upload the original file along with your vehicle details and requirements (and stock datalogs if available).
Expert calibration
Our tuners craft your custom map to your specification. Simple jobs such as a Stage 1 or a delete/solution are usually completed within 20 minutes. Stage 2 & 3 jobs can take longer depending on workload - please get in touch to check expected timescales.
Download & write
Receive your tuned file back through the portal and write it to the vehicle with your read tool.
Datalogging and analysis
It is advised to record some datalogs either on the road or dyno (if available) before and after tuning. These will be reviewed to ensure that the tune is working as expected - essential for safety and achieving the best performance. After reviewing the logs the tuner may upload a revised tune for you to flash and datalog again.
