The value should be optimized for the specific type of car 18 28 is generally the ideal value The factory standard engine control system performs further compensation meaning that even if you reduce the value to 10 to save on fuel if the factory stand ard computer decides based on the lambda signal that the mixture is insufficient then it will modify it possibly even up to 25 28 if it can This can even lead to an increase in fuel usage instead of the hoped for decrease The exact value in question depends on a great number of tiny factors for example lambda speed and values can vary even among cars of identical make The ideal value can be determined with a little experi mentation Many factory standard engine control systems are sensitive to even a few percentage points of difference which can potentially mean more work with determining the correct value which might even require a special tool in these cases such as an error code reader or an engine diagnostics tool Engine temperature detection cfgADPUEna Used to select the function of the analog input that is the method of temperature measuring Its possible values are NIC or thermostat E85 mode switch cfgMaSw Can be set to have the system switch over when the purple wire is grounded Ultimately this is the entire device s master switch which allows the activation of ethanol fuel mode from inside the cabin For BioETUN this value is 2 p18 and will never need to b
