Primary Fuel and Octane

Choose your desired fueling. Higher octane ratings will have reduced knock adaptions as stock setting are designed for 91 AKI Octane. This will still leave the main knock detection program active but reduces the knock adaption values as they are overly sensitive. High octane will be considered 93 octane AKI or greater in the US, 98 octane RON or greater in the EU, or E30 to E85 mixture. Do not select 93 octane if you only have access to 91, you will lose power via DME pulling timing.
