Map Switching

 

MAP Switching is a revolutionary feature that allows the driver to select from two performance levels while driving.

NOTE: The feature is available for the following ECU versions only and the vehicle must be tuned with an EcuTek Map Switching ROM

  • 2001/2002/2003/2004 UK WRX (af53x, ah75x)
  • 2001/2002/2003/2004 US WRX (af42x)
  • 2001/2002/2003/2004 UK & EU STI (ag82x, ah99x)
  • 2003/2004 JDM STI and JDM Spec C (ah58x & ah59x)

No other ECU versions are supported at this time. The bracketed IDs above are the ECU versions as shown on the lid of the ECU and reported by DeltaDash. The list above allows anyone wishing to have this feature added to their vehicles to check that their ECU version is supported before visiting a tuner. For example af53x, means any ECU label beginning with af53, such as af530, af531, af532.


Switching Maps

EcuTek Map Switching allows the dynamic selection of two sets of performance levels. To switch between these performance levels, the driver simply holds full throttle and toggles the rear heated window switch from off to on. This may be done with the engine off or on, but the ignition must be on. The performance levels may also be switched from DeltaDash using the User Tuning feature.

How it Works

EcuTek have customised the function of the software in the ECU to allow dynamic switching between two sets of performance maps. Selection of the performance level via the car dashboard or DeltaDash determines a choice between two sets of boost control configuration within the ECU. One setting might be for a constant 0.5 bar (7psi) while the other might be 1.2 bar (17.5psi), tapering to 1 bar at the redline.

Applications

The two performance levels may be specified by you to your chosen EcuTek tuning partner. You may choose to have one performance level for road use and one for drag racing. Alternatively, you may choose to have a high performance and an economy mode.

How to get it

To use Map Switching on your WRX, your ECU must be reprogrammed with a special Map Switching ECU calibration. If you have already had your ECU reprogrammed by an EcuTek tuning partner, contact them for an upgrade. If you are a new customer, simply choose an EcuTek partner from the dealer list and specify that you would like the Map Switching feature when your ECU is tuned.
