Thanks to the supplied AMP plugs, these chiptuning units can be easily connected and they scrupulously respect the power reserves and motor protection systems of the german manufacturer.
am very pleased with the whole process. You have to watch the transport package, the parcel has got into my hands in poor condition TUNE PEDAL outside the box and the bag torn.
Great Service, keep as it is and no improvements needed
