If you’re thinking about tuning your car, one of the first questions that comes to mind is:
How long does a remap actually take?
At Remaps Bristol, we know your time is valuable. Whether you’re squeezing it in during a lunch break or planning to get back on the road for work, knowing the timeframe helps you plan.
The good news? For most vehicles, the remapping process is quick, simple, and usually done the same day.
Here’s a breakdown of how long a remap takes — and what affects the time required.
Typical Time for a Car Remap
For most Stage 1 remaps, the process takes 1 to 2 hours from start to finish.
This includes:
- Running a full diagnostics check
- Reading your vehicle’s original ECU software
- Modifying the tuning file based on your vehicle and goals
- Uploading the new software (flashing the ECU)
- Final checks and road test
If your vehicle is healthy and there are no unexpected issues, we can often have you back on the road within 90 minutes.
What Can Affect the Time?
While many remaps are quick, some factors can extend the job slightly:
1. ECU Type
Some newer vehicles have encrypted ECUs that take longer to read and write. Others require the ECU to be removed and bench-tuned, which adds time.
If your car needs bench tuning (rather than OBD port access), allow up to 3 hours.
2. Diagnostics Issues
We always carry out a full pre-remap health check. If we find warning codes, sensor issues, or other faults, we’ll discuss them with you before proceeding.
Fixing small issues can delay the process, but it’s worth it to ensure a safe, effective tune.
3. Custom Maps and Data Logging
If you’re going for a Stage 2 or Stage 3 remap, or if your vehicle has lots of aftermarket parts, we may need to log data on the road and fine-tune the file.
This can extend the time to 2 to 4 hours, depending on the setup and how many adjustments are needed.
4. Mobile vs Workshop Service
We offer both mobile and in-house remapping in Bristol.
Mobile remaps are just as quick for most cars, but setup and teardown (especially in tight spaces) can add 15–20 minutes compared to workshop conditions.
Either way, we’ll keep you informed and give a clear estimate before we begin.
How Long for Vans and Commercial Vehicles?
Most vans and commercial vehicles follow the same timeframe as cars:
- Stage 1 van remap: 1.5 to 2 hours
- Stage 2 or custom remap: Up to 3 hours
If you’re running multiple vans or a fleet, we can schedule tuning over a few days to reduce disruption to your business.
How Long for Gearbox (DSG) Remaps?
If you’re also having your gearbox remapped (e.g. DSG, ZF auto), allow an additional 1 to 1.5 hours.
Gearbox tuning can be done at the same time as the engine remap, and we often offer discounted pricing when you book both together.
Can I Wait While It’s Done?
Yes — if you visit our workshop, you’re welcome to wait while we remap your vehicle. We have a comfortable space and free Wi-Fi, and we’ll let you know as soon as it’s ready.
For mobile jobs, many of our customers relax at home, carry on with work, or even run errands nearby while we get the job done.
We’ll always keep you updated and let you know when we’re nearly finished.
