Diesel Engine Remapping
for TDI, CDI, dCi and HDi engines
Remapping a turbo diesel re-calibrates the engine's own software, rather than adding a box to alter its signals.

Overview
Diesel Engine Remapping across the UK
Whether it is a TDI, CDI, dCi, HDi, CRDi or JTD engine, the principle is the same: the ECU's stored maps for injection, boost and torque limits are rewritten within safe margins for that engine. The result is stronger acceleration, particularly in the mid-range.
People sometimes ask how a remap compares with a plug-in tuning box. A remap changes the ECU's own calibration and is tested on a dyno; a box intercepts sensor signals. Our guide explains the differences fairly. Across the 965 diesel engines in our catalogue the average stage 1 gain is 34 bhp and 73 Nm.
Who it suits
- Owners of turbo diesel cars and SUVs
- Drivers choosing between a remap and a tuning box
- Anyone wanting a calibration written for their exact engine
The process
How it works
- 01
Tell us about your vehicle
Search your engine or request a quote with your make, model, engine and registration.
- 02
We confirm the details
We contact you by SMS or call back, check the vehicle and confirm what is possible.
- 03
Your local site books you in
Your local Remap Experts site arranges the work and answers your questions.
- 04
Remapped and tested
The work is fully dyno tested, with a 30 day money back guarantee and a lifetime software warranty.
What to expect
- Noticeably stronger acceleration, mostly between 1,500 and 3,500 rpm
- A calibration written for your engine, not a generic file
- Figures confirmed on a dyno
Worth knowing
- Extra torque puts more load on the clutch, dual-mass flywheel and gearbox, so worn parts should be checked first.
- Tell your insurer about the remap before you book.

Questions
Diesel Engine Remapping: your questions
Is a remap better than a tuning box?
They work differently. A remap rewrites the ECU's calibration for your engine; a box alters sensor signals. See our guide for a fair comparison.
Will it work on my engine?
Search your make, model and engine to see our figures. If your engine is not listed, call us.
