Is re-mapping better or simply different from chipping?
OBD Engine mapping is the modern version of chipping. When you “chip” a car you basically put in a chip that has a set of data already burnt onto it, into your ECU. When you OBD remap an ECU, you save off the data currently stored on the chip and overwrite it with the performance data. This then allows you to apply different maps where applicable and also restore the original data should you require it. The benefit obviously of this is that it means you have not changed any standard part of the car and therefore warranty is unaffected etc. What you must remember is that this is not some gimmick promise item that fools the engine into thinking something else (oh how I wish those things would be banned under the sales description act!), it is the real version of engine tuning using a modern approach.
