A common question before booking is how long a remap actually lasts. The short answer is that a remap is a permanent change to your ECU software — it does not fade or wear out over time.
Permanent, but not untouchable
Once the optimised file is written, it stays in place and performs exactly the same on day one and year five. The only common way it gets removed is if a dealer reflashes the ECU during a software update or recall.
What can overwrite a remap
Your file can be overwritten by:
- A dealer software update or recall that reflashes the ECU
- Certain major electrical or ECU repairs
- Deliberately returning the car to its saved original file
If a dealer does update your ECU, the remap can simply be reapplied afterwards. Because we store your file, restoring it is quick and straightforward.
We keep your file
Should a dealer update ever wipe your remap, we can reapply it — and return the car to standard whenever you need.
Key takeaways
- A remap is a permanent change and does not fade over time.
- It performs the same for the life of the car.
- A dealer software update or recall can overwrite it.
- We store your file so it can be reapplied or reversed anytime.

Will my remap wear off over time?

What happens if a dealer updates my ECU?
A dealer update can overwrite the remap, but because we store your file we can simply reapply it afterwards.
