Custom Code v6.9 (to be released soon) changes the activation button from FAR DOWN to SHORT UP on the rocker switch.
Max Cooling On-The-Fly: with a simple button combination sequence, you can enable the Max Cooling option without re-flashing the car!
There will now be two option available for cooling your engine: Regular cooling and Max Cooling. Use “regular cooling” with regular driving, then switch to “Max Cooling” with a quick and easy button sequence. Max Cooling is achieved by lowering the target engine temperature and increasing the target intercooler coolant volume flow.
If you want to use that feature please connect a Car to MG Flasher App, then select your map and from the Flashing Car Options page enable Cooling section. It allows you to choose some extra options which can be adjusted by your own preferences.
The “Regular Target Engine Temperature” option should be treated as preferable for everyday driving - that is set when Max Cooling On-The-Fly is not enabled.
The “Max Cooling On-The-Fly” option allows you to adjust: “Max Cooling Target Engine Temperature” and “Max Cooling Target Intercooler Coolant Volume Flow”.
Target engine temperature and intercooler coolant volume flow will change between your slider settings (configured before flashing) and the default values when toggling Max Cooling On-The-Fly. OEM target engine temperature is 110°C and the OEM intercooler coolant volume flow is 1500 L/h under full load operation. You can adjust the values from 90°C - 110°C and from 1500 L/h – 1800 L/h.
