Ethanol Adaptation: General
The engine management system adapts itself according to the ethanol content in the fuel and resets a number of parameters so that the engine shall run optimally. Ethanol adaptation takes place automatically after refuelling amongst other things.
However, in connection with repairs it may be necessary to force the engine management system into an automatic ethanol adaptation, this is performed with Tech 2. The ethanol content can also be entered manually using Tech 2.
An algorithm has been developed that uses the lambda sond's signal for calculating the current ethanol content in the fuel.
