Need an ECU Remap in Sussex? Call Hyper-Tune!

At Hyper-Tune, we’re proud of the reputation we’ve established as the leading ECU remapping experts in Sussex. One of the reasons why our customers choose to come to us for car tuning, rather than go to a nearby rival, is because of our friendly and open attitude. We keep our process as transparent as possible, and are more than happy to explain our work to you in layman’s terms, so you can get a full idea of what ECU remapping involves.


With that in mind, on this page we’ve detailed three different car tuning methods, each of which is useful in its own right. If you have any questions regarding the below, or indeed any of the services we offer the Sussex area, don’t hesitate to call us on 01798 342400 .

Types of ECU Remapping

OBD Remapping – Seen as the most efficient and non-intrusive way of carrying out an ECU remap, OBD remapping is suitable for vehicles dating back to the early 1990’s. To carry out this method of car tuning, we don’t even need to pop the bonnet. We’ll connect our remapping equipment to your vehicle’s OBD port, which provides direct access to its ECU unit.


Chip Tuning – The original way to carry out ECU remapping was known as chip tuning, and we still carry it out for Sussex motorists who drive older vehicles. This involves removing the read-only chip within an ECU and replacing it with one that contains a different, tuned map. It’s the most manual and difficult of the aforementioned methods, and isn’t necessary with modern vehicles, for which OBD and BDM car tuning can be employed.

BDM Remapping – There are a number of reasons why we might not be able to utilise OBD remapping on a Sussex customer’s vehicle. Firstly, the car might not even have an OBD port. Secondly, it could be faulty. Finally, it may have been protected from car tuning by the manufacturer. In these cases, we’ll look to access your ECU’s EEPROM, or Electronically Erasable Programmable Read-Only Memory. This is where your ECU map is found.


BDM stands for Back Door Module. BDM tuning involves connecting to your ECU’s circuit board directly. To do this, we’ll employ a jig that holds the chip in place, and machinery which can connect to it via electronic pins. Our Sussex based team are highly experienced with both OBD and BDM tuning, so you can rest assured your vehicle and its components will not be damaged throughout the ECU remap process.
