4. the width of the window to accommodate the full fluid flow is vital Setting up the fail safe should only be done after the car has been tuned or the jet jets sizes are finalised Recommended steps to set up the fail safe 1 Adjust the SC to display 5 6 bars at full power 2 Make a mental note of the number of displayed bars during spool up This is made easier at higher gears 3 Set the WL to match the number of spool up bars It is recommended to allow 2 3 clicks below that point to avoid false triggering Full span of WL is 20 clicks covering from 0 bar to 4 bars 4 Same procedure is used to set up the WH allow ing 2 3 clicks above 6 bars Full span of WH is 20 clicks covering 4 8 bars This completes the fail safe set up Setting up the alternative Fail safe Channels 1 The Map Switching Channel HFS 3 only The orange wire from the grey RJ48 connector orange is dedicated for the use of MAP Switching when an ECU is equipped with this input This wire is factory configured to send out a voltage of 4 7V DC under a no fault condition from idle to full boost This voltage will switch to Ov upon a fail safe activation or the gauge is switched off Other voltages such as 0 5V or 8V can be user configured page 12 7 This is by far the most effective method to save your engine from lack of water injection A jumper link can ph invert the map switch output if necessary 2 C
