Just a quick question.
I have just bought 2001 wrx with twin ECU and was told you hold your finger on rear heated screen switch for 3 seconds whilst excelarating and this switchs between standard and modded ECU, Is this right ? Is this where tuners put there switch?
Opinions please.

AFAIK this was an option on EcuTeK re-maps for the bugeye. Full throttle while toggling using the rear screen heater button...... allegedly ! Technically there is space on the ROM to do this but not sure why ?

I'm still not sure if this is Scoobynet folklore or not ?, personally if my ECU returned to the OEM setting the car would cr@p itself !!!!!!!!!!!!!

Switching Maps
EcuTek Map Switching allows 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, so long as the ignition switch is 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 configurations within the ECU. One setting might be for a constant 0.5 bar (7 PSI) whilst the other might be 1.2 bar (17.5 PSI), 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 on 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.
