Live Map Switching

• Map Switching allows the driver to independently select power levels based on the octane of the fuel or fuel type by using the cruise control stalk. Map switching can be performed with the vehicle running without the need to shut the engine off.
  • Example Map Slot Setup:
    • Slot1 – Stock Power
    • Slot2 – 93 Octane
    • Slot3 – 100 Octane
    • Slot4 – E85
    • Slot5 – Valet

Since Map Switching can be customized depending on the individual please contact us when purchasing if you’d like a different setup or would like a custom map slot.

 – M-Engineering also provides PDK Tuning –

HOW DOES IT WORK?:

• You are responsible for shipping the ECU to M-Engineering to be flashed.
• When you calculate shipping at checkout, this is for return shipping costs to you.

What octane are these tunes compatible with?
Files are tuned accordingly to your preference.

If I add an exhaust or intake, do I need to reflash my car?
No.  Each individual table is tuned. Unlike others that do a global change to files, M-Engineering enables the ECU to adapt to basic bolt-on modifications like exhaust, intake, headers, etc. The only time you need to re-reflash your vehicle is when you change fuel components, turbo sizes, or engine internals, etc. Pro-Tunes are available for your heavily modified vehicle.
