Stage Hardware Requirements
Stage1 - Designed for a vehicle with the following modifications:
headers: Stock
Exhaust: Stock or aftermarket
Air Filter: Stock or aftermarket drop-in filters
Fuel System: Stock
Stage2 - Designed for a vehicle with the following modifications:
Headers: Aftermarket headers are required.
Exhaust: Stock or aftermarket
Air Filter: Stock or aftermarket drop-in filters
Fuel System: Stock
Minimum Octane Requirements
91 Octane - For use with 91 octane (R+M)/2 or 95RON fuels minimum. 94 octane fuels with 0% Ethanol should also run the 91 octane file.
93 Octane - For use with 93 octane (R+M)/2 or 98RON fuels minimum.
100 Octane - For use with 100 octane (R+M)/2 or 105 RON fuels minimum.
*Warning*
Using a lower octane than is designated by the calibration can promote increased engine wear and in severe cases catastrophic engine damage. Never run a map designed for high octane with low octane in the fuel tank. E.g. Do not run the 100 Octane map with 93 octane fuel in the tank.
Torque and Horsepower Output
These dyno charts represent typical power output to the wheels as tested on a DynoJet 424 Linx dynomometer.
“Max Gain” represents the largest delta between any two points on the graph at the same RPM.
“Peak Gain” represents the overall delta of the highest reading per dyno plot.
We break up power gains into % and numerical gains. We know that every dyno reads a bit different, particularly between manufacturers, so we have utilized the percentage gains which should be similar and independent of the dyno. The numerical delta gains are a more user friendly value but may not read similar on every dyno.
Stage1
91 Octane (R+M)/2 or 95 RON (Map Slot 1)
93 Octane (R+M)/2 or 98 RON (Map Slot 2)
100 Octane (R+M)/2 or 105 RON (Map Slot 3)
Stage2
91 Octane (R+M)/2 or 95 RON (Map Slot 1)
93 Octane (R+M)/2 or 98 RON (Map Slot 2)
100 Octane (R+M)/2 or 105 RON (Map Slot 3)
If your parts configuration or octane fall outside of the bounds of these maps we do offer ProTuning services past what is offered here in the maps.
Custom Features
Map Switching and Left Foot Braking are only available through M-Engineering or our authorized dealers. These features all require custom code that has been written in house by our staff of reverse/software engineers.
Feature | Description |
|---|---|
Live Map Switching | This feature allows multiple calibrations to be stored on the ECU at one time. Utilizing the cruise control stalk, you can quickly and easily switch between maps while the car is running. More Info on how Live Map Switching works and directions are located here |
Left Foot Braking | This is a nice feature to have for track enthusiasts who like to use both feet while racing. This extends the time you can press the brake pedal before all throttle input is cut off. This does not disable the OEM safety control and will still perform as desired in an emergency situation. |
