Process of Car Remapping at GMP Autos

Step 1: Our ECU car remapping process utilises the vehicle’s OBD port for the services, with most of our work leaving no visible trace or need for additional components.

Step 2: Using specialised equipment, we read and copy the original data stored in the ECU’s chip (EPROM).

Step 3: We then reprogram it with new and optimised data. These data maps, which control key aspects like fueling, ignition timing, and boost, are adjusted to enhance engine performance.

Engine remapping not only boosts engine performance but also improves throttle response, drivability, and fuel economy. For specific performance gains, get in touch.

Potential Benefits of ECU Remapping

If you’re considering an ECU remap, here are some compelling advantages:

Customisation Options

Remaps are fully customisable to suit your driving needs. You can have multiple remap settings, allowing you to switch between them based on different terrains and driving conditions.

Enhanced Power and Torque 

Remapping removes manufacturer-set limitations, allowing for precise adjustments based on your local conditions, such as altitude and fuel quality. This fine-tuning boosts power and torque output.

Improved Performance and Drivability

An ECU remap enhances your vehicle’s overall performance and drivability, making it easier and more enjoyable to drive. Typically, performance gains can be as much as 40%.

Better Fuel Efficiency

By optimising fuel control, ECU remapping improves miles per gallon, maximising your fuel efficiency and saving you money.

Increased Throttle Response

Stage 1: Light reprogramming for a modest performance boost, typically costing a few hundred pounds.

Stage 2: Involves additional modifications, such as a new air filter and exhaust improvements, costing around £1,000 or more.
