Why is re-mapping a better option than a plug in tuning box?
The option other than a proper re-map is a plug in tuning box. We often get asked which is best. The simple answer is a full re-map. A tuning box simply gives false sensor values throughout the complete rev-range. The ECU is constantly told (or fooled) that not enough fuel is entering the engine, so it over-fuels the engine to gain performance. Although performance gains are made, these are at the cost of high emissions, higher engine temperatures, and general poor running of the engine. Many sellers of tuning boxes state that they are completely invisible, as they can be removed. This is not the case, diagnostics tools will show errors which have been caused by the incorrect fuelling. Problems related to tuning boxes are poor running, black smoking from the exhaust, rough idle, and clogged injectors and even engine’s cutting out.
