Frequently asked questions

Q. How long does it take to custom chip remap a vehicle?

At Manchester Remapping we take ECU remapping very seriously and not just as a simple install of some software like so many other companies will. The file is written by us and installed by us, this is only done after your car has been fully checked over for any undetected faults that may be unknown to you affecting the running of the vehicle.

After it has been re-mapped it is then tested and adjusted until we have gained the maximum benefit that can be attained from the remapping.

Due to this we cannot give the quick and easy guide times of our competitors who are simply installing a file. You should however be aware that anyone offering this service in a matter of 30 mins or an hour will not be providing the same level of service, testing and tuning that we deliver here at Manchester Remapping as standard.

We normally like to have the vehicle for a couple of hours minimum, this should give us enough time to complete full tuning, remapping, testing and rectifying faults.

Q. Do you offer a custom chip remapping mobile service?

We do now offer a mobile service, as in the previous answer, the remapping of the vehicle is simply one part of the service, testing and tuning that we deliver as part of our remapping service. We need access to our specialist diagnostic equipment and the internet if need be to ensure that the remap we provide is truly getting the most from your vehicle.

Therefore offering a mobile service for remapping should be as simple as adding a new file into the ECU overwriting the old version, after fully testing and driving the vehicle to make sure it suits both the vehicle and the requirements of the driver, then and only then will be happy with the tune, this is something we feel strongly about as so many, so called mobile re-mappers simply flash the ECU with generic files bought off the internet and flee, be aware that these companies offering this mobile remapping service are not even doing half the job.

Q. Does an ECU remap invalidate my manufacturers warrenty?

This is a point of some contention, generally it is perceived that for a manufacturer to cancel a warranty due to someone having after-market services or parts added to their vehicle is an anti competitive practice and therefore against European laws.

However if it is stated in your documentation that remapping your ECU will invalidate the warranty, then it will probably do so.

Unlike many other remapping companies we only carry out custom chip remaps which are tested and tuned to suit your vehicle and your needs, we naturally only modify the vehicle to within the safety limits of the vehicle and its components and certainly will not push your vehicle beyond those limits.

The European law states that a manufacturer cannot cite after-market services or parts to void a warranty or reject a warranty claim. The manufacturer need to prove that the service or part is the direct cause of the failure and the Burdon of proof rests with them.
