All our Astra J VXR remapping is carried out serially, through OBD II/diagnostic port directly into the vehicle's ecu. All our maps are bespoke written for us to suit your requirements. All our ECU upgrade software is installed on your car whilst on our rolling road optimising fuelling, boost and Ignition maps. This enables us to see and rectify any underlying faults or problems and to ensure that the calibration is 100% accurate and safe for your car before handing it back to you, along with the full power and torque print outs. If your car does not fit into the categories listed, for example you have a different exhaust configuration, we can and will write a bespoke map and tailor it to your vehicle.
