2 WARNING! THE WEISTEC WMI/ASV SYSTEM IS DESIGNED AROUND THE USE OF A MAXIMUM CONCENTRATION OF 50% METHONAL MIXED WITH DISTILLED WATER ONLY. METHANOL IS A TOXIC AND HIGHLY FLAMMABLE CHEMICAL. 100% METHANOL EASILY IGNITES AND BURNS VIGOROUSLY WITH AN ALMOST UNDETECTABLE FLAME. METHANOL CAN BE ABSORBED THROUGH THE SKIN AND EVEN SMALL AMOUNTS CAN CAUSE BLINDNESS OR EVEN DEATH. USING THIS FLUID AT HIGH PRESSURES WITHOUT DILUTION, IN AN UNDER-HOOD ENVIRONMENT WITH NYLON LINES AND PUSH-TO-CONNECT FITTINGS IS VERY UNSAFE. GREATER THAN 50% CONCENTRATION OF METHANOL WILL PROVIDE LITTLE TO NO ADVANTAGE AND WILL CAUSE SAFETY ISSUES NOTE: WEISTEC ENGINEERING HOLDS NO RESPONSIBILITY FOR ANY ENGINE DAMAGE OR PERSONAL INJURY THAT RESULTS FROM THE MISUSE OF THIS PRODUCT, INCLUDING BUT NOT LIMITED TO INJURY OR DEATH CAUSED BY THE MISHANDLING OF METHANOL 1

9 II. MAP Adapter Installation 1. Disconnect ground from battery 2. Secure vehicle on a lift IF PROPER MERCEDES PROCEDURE IS NOT FOLLOWED, THE VEHICLE MAY BE PERMANENTLY DAMAGED AND/OR MAY FALL OFF THE LIFT 3. Remove airboxes 4. Locate plastic plug in passenger side intake manifold 5. Twist the plastic plug to unlock it and pull it out of the intake manifold. Be careful to prevent any foreign objects or material from falling into the manifold 6. Install Weistec MAP Adapter in the intake manifold by first lubricating the O-ring and then pressing it into the manifold. Twist the adapter to lock it in place just as the OEM plug was locked 7. Connect Map Adapter to the boost port on the injection controller using a section of the supplied rubber vacuum line 8

10 III. Charge Pipes 1. Remove OEM turbo charge pipe couplers. It helps to unbolt the mounting brackets of the intercoolers to allow them to move forward slightly, giving more room to work with 2. Install Weistec Couplers in place of the OEM couplers. 3. Once all adjustments are done and the couplers are fitting properly, proceed with tightening all the clamps and mounting hardware 4. Select which nozzles will be used, applying blue Loctite before screwing the nozzles into the injector bodies 5. After nozzle selection and installation with Loctite, press the barbed Weistec Injector bodies into the ports on the Weistec couplers and tighten the supplied clamps 6. Plumb the injectors into the WMI system using the supplied ¼ plastic line and supplied QD fittings, per the installation diagram. 7. Route the plastic line away from heat sources and secure the line with zipties to prevent damage from vibration and rubbing. 9

11 IV. Tank Installation 1. Open trunk 2. Position the tank on the side paneling in the most convenient mounting location in terms of installation and future filling of the tank 3. Mark where the 4 bolt holes need to be drilled into the side paneling 4. Remove the tank and drill the 4 holes 5. Bolt the tank in place using the supplied hardware 10

12 V. Tank Wiring and Plumbing 1. Begin by locating the supplied 20ft section of ¼ plastic hose and 16-4 Service Cord 2. Place both in the trunk 3. Press one end of the ¼ hose into the outlet of the pump 4. Wire the 16-4 Service Cord to the pump and the tank level sensor a. Black to Black wire on pump b. Red to Red wire on pump c. White to one wire on the level sensor (polarity does not matter) d. Green to remaining wire on the level sensor (polarity does not matter) 5. Find a suitable location to drill a hole through the spare tire well large enough to fit the wire harness and ¼ plastic hose 6. Route the harness and hose through the hole. 7. Once out of the spare tire well, route the harness and hose up and over the rear Subframe and differential on the right side of the vehicle (for Left Hand Drive Vehicles). Be sure to avoid tight turns that kink the plastic hose. Use zip ties to keep the harness and hose away from moving parts 8. Route the harness and hose between the body and the right-side plastic under tray to the front of the vehicle and then up into the engine bay where the cabin filter is located. 9. Route ¼ Plastic Line to the Tee Fitting 11

13 VI. Controller Installation 1. Find a suitable location and mount the Injection Controller 2. Reference included wiring diagram 3. The Injection Controller is wired to the following a. Ground (black wire) b. 12V (red wire) c. Ignition/arm switch (yellow wire) d. Indicator LED (violet +, gray -) e. Pump (pink +, orange -) f. Tank Level Sensor (white +, brown -) 4. On the supplied Controller harness, ground the black wire 5. Connect the red wire to a 12V source 6. Connect the yellow wire to an ignition source. 7. The pump and tank level sensor wires will be wired to the 16-4 Service Cord a. Pink Wire to Red Wire on 16-4 Service Cord b. Orange Wire to Black Wire on 16-4 Service Cord c. White Wire to White Wire on 16-4 Service Cord d. Brown Wire to Green Wire on 16-4 Service Cord 8. The Indicator LED can be installed either in the engine bay, or somewhere visible inside the passenger cabin a. Violet Wire to + wire on LED b. Gray Wire to Wire on LED 9. Connect the boost port on the Controller to an open port on the MAP Block Pump/Tank Flush After all wires are hooked up, add water to the tank and, with the hose pointed into a container, press and hold the TEST push button on the controller module. The TEST button can be used to test the system. The pump speed will gradually increase from zero to full speed within 3 seconds and then remain full for another 3 seconds before stopping. Repeat the TEST button procedure until you are sure the system is free of any debris that may have been in the lines or tank. Drain the water out of the tank and refer to the next section on installing the nozzle. 12

15 VII. Controller and Nozzle Adjustment 1. The Weistec Injectors are shipped with the smallest nozzles installed. As more power is made, it will be necessary to replace the nozzles with the provided larger nozzles a. Stock Turbos Smallest nozzles recommended b. W.3 Turbos Medium nozzles recommended Large Nozzles can be used but may require custom tuning. c. It is not possible to use different size nozzles in each injector d. After nozzle selection, make sure to apply a small amount of blue Loctite to the threads of the nozzles that screw into the injector bodies. This will prevent them coming loose and falling into the charge piping. 2. The Injection Controller has two adjustment knobs. One for start pressure and one for full pressure. a. Recommended Start Pressure is 8psi b. Recommended Full pressure is i. Stock Turbos - 19psi ii. W.3 Turbos - 22psi 3. Fine adjustment of start and full pressures can be performed on a dyno by an experienced tuner. Fluid Compatibility Under NO circumstances should any hydrocarbon based fuel ever be used with this system. Water and methanol are the ONLY fluids to be used 14
