SL63 Weistec M156 Supercharger System Installation Guide Stage 1 / Stage 2

WARNING! DO NOT HAVE YOUR ECU REPROGRAMMED ANYWHERE BUT AT WEISTEC FOR THIS SUPERCHARGER. THE AMG 63 USES AN ELECTRONIC THROTTLE CONTROL (ETC), WHICH IS CONTROLLED BY THE ENGINE CONTROL UNIT (ECU) AND THE CALIBRATION INSIDE. A REFLASH DOES NOT PROPERLY RECALIBRATE THE ENGINE MANAGEMENT SYSTEM; THIS CREATES A DANGEROUS SITUATION THAT COULD RESULT IN A STUCK THROTTLE AND CAN LEAD TO INJURY OR DEATH. WEISTEC FULLY REPROGRAMS THE ECU TO MERCEDES STANDARDS, AND ENSURES THAT ALL ENGINE SAFETY CONTROLS ARE FULLY FUNCTIONAL. 1

WARNING! THE WEISTEC M156 SUPERCHARGER AND ACCOMPANYING PROGRAMMING ARE DESIGNED AROUND THE USE OF 91 OCTANE FUEL OR HIGHER ONLY. BEFORE YOU RUN YOUR MERCEDES WITH THE WEISTEC M156 SUPERCHARGER INSTALLED EVEN ONCE, YOU MUST EITHER DRAIN THE FUEL TANK COMPLETELY AND FILL IT UP WITH 91 OCTANE, OR BEGIN USING 91 OCTANE IN YOUR MERCEDES TWO COMPLETE FILLUPS BEFORE INSTALLATION. 2

WARNING! IF YOU ARE NOT EXPERIENCED IN THE AREA OF AUTOMOTIVE MECHANICS, WE STRONGLY URGE THAT YOU REFER THIS INSTALLATION TO A CERTIFIED INSTALLER OR TECHNICIAN. 3

WARNING! THE WEISTEC M156 SUPERCHARGER MUST BE FILLED WITH 160 ml OF PROVIDED OIL PRIOR TO ROTATION OF THE COMPRESSOR SCREW SYSTEM OR YOUR WARRANTY WILL BE VOIDED. 4
