Tank & Pump Installation Guide

Step 1: Thoroughly wash and flush out the tank with water until the tank is free of any plastic debris.

Step 2: Place the tank and mount the brackets at the desired area in the trunk. The tank exit fitting must be facing the back of the car, like in the reference picture.

Step 3: Angle the 90 degree fitting to face down like in the reference picture. Make a hole right below it, so you can connect the hose directly from the fitting to the spare tire area without any kink or obstructions. Step 4: Mount the Pump under the carpet in the spare tire area. Step 5: Take the Nylon Tubing and route them accordingly (Tank Exit to Pump Inlet & Pump Outlet to the front of the car through the driver side grommet)

Step 6. Attach the pump's ground wire to the chassis or any solid metal that is free from paint or coatings. (ie. bare chassis under the trunk mat). Use a ring terminal & fastener to ground the black wire. The pump’s red wire will get attached to the Green/Red wire from the ICM(Injection Control Module) Harness, by using the Heat Shrink Solder Butt Connectors.

Step 7. Using the tank brackets, mount it around the tank to secure the setup. Using the heavy duty velcro at the bottom of the tank surface can also help to secure for heavy cornering.

ICM(Injector Control Module) Harness & Nylon Tubing Installation Guide

Step 1: Take the Nylon Tubing from the back of the car and through the driver side gromment. (Remove the door seals and tuck the Nylon tubing underneath to get a clean setup. Step 2: Make a hole in the grommet or drill a 1/2inch next to the grommet, so you can feed the nylon tubing through it. **Please make sure to take extra caution from damaging or puncturing OEM wirings that goes through the grommet. **

Step 3: Take the Green wire from the ICM Wiring Harness(Pump(+) Positive). Tape the wire to the nylon tubing and feed it through the vehicle grommet from the engine bay, and take it to the pump's location in the back of the trunk. Connect wire to Pump(+) by using a heat shrink solder connector.

Nozzle & Check Valve & Solenoid Installation Guide

*All Hardware MUST BE installed AWAY from hot exhaust & turbo.*

Step 1: Using the 1/8" NPT Tap, drill the cold pipe between the throttle body & Boost Map sensor.

Step 2: Using the nylon tubing, connect the Nozzle & Check Valve & Solenoid as shown in the reference picture above. The check valve must be installed between the nozzle & solenoid. The Nozzle & nylon meth line to the Solenoid "INLET" must be connected AFTER purging the system towards the end of this guide.

Step 3: Assemble the Nozzle & Nozzle holder as pictured below.

*Do not connect the nozzle to the pipe until instructed*

Step 2:

• Orange/White - Solenoid(+) Positive (Connect it to one of the black wires of the solenoid by using a Heat Shrink Solder Butt Connector. When one black wire of the solenoid is used as Positive(+), then the other black wire must be used to ground.

Step 3: Use a ring terminals & fasteners to ground the both ground wires of the solenoid & ICM Harness

• You MUST use the OEM Factory Ground locations to ground your wires, nowhere else! Failing to do so can burn up your meth module, and they are NOT covered under warranty.

• Find a factory ground locations like the picture below. Solenoid & ICM Harness Ground Location Example:
  

Step 5: Connect the other end of the ICM Harness to the ICM(Injection Control Module)

CANBUS OBD Harness Installation Guide

Step 1: Locate the CANBUS OBD port(aka Diagnostic Port) under the hood, and simply connect and secure it with electrical tape if needed. *If you have been provided with an In-Cabin OBD2 cable, route it thru the grommet and connect it to the in-cabin OBD2 port.*

Step 2: Using the provided Posi-tap, strip & connect the Blue wire from the CANBUS OBD Harness & tap the #1 wire on the Map sensor mounted on the intake manifold to get boost pressure signals. Black wire(#4 wire) on the map sensor is ground, so please do not connect it there. Most Platform's Map Sensor #1 Wire is either White/Gray/Blue.

Step 3: Connect the other end of the CANBUS OBD harness to the ICM(Injection Control Module)

Power Wire

• Red - 12V Power (Connect it to the double fuse tapper kit by using a Heat Shrink Solder sleeve butt connector. Open up the fuse box under the engine bay. Grab a 15amp fuse from the Sensor1 slot and put it in the fuse tapper that's been provided. You now have two 15 amp fuses on the fuse tapper. One for the existing 15 amp fuse to power the existing vehicle sensor, and another 15 amp fuse to power the meth kit.

By now, you should have everything connected except the Solenoid INLET Meth Line & Nozzle.

Connect the vehicle battery, Put the vehicle on ON position by pressing Start button twice with the brake pedal depressed.

Bluetooth Module & App Guide

Step 1: Connect the Bluetooth Module to the ICM(Injection Control Module)

Step 2: Download & Install the App

Android Users: Click here to download

iOS Users: Click here to download

Step 3: Launch the App & Go to the Setting Tab.

*Your phone's Bluetooth & GPS Location Service must be turned on, and must be grant the access when the app asks you for a permission when you first launch the app. If you accidentally denied the access, then you must reinstall the app or grant the access by manually changing it through the phone's app settings.

Step 4: Scroll down and turn on the Auto-Connect feature.

Step 5: Go to the Real Time tab, and press Connect. It may take a minute or two to pair and connect.

Make sure all 3 (Bluetooth, Uncle Chip, OBD2) are lit up green on the main screen. If they are not lit up green, do NOT move on to the next step, and recheck your ground connections & power wires.

Once the app is running as it should, you can now move on to purging the system.

Test the Meth Flow & Purge the AIR out of the system

Step 1: Put distilled water in the Methanol Tank, and prime the system by pressing "Meth Test Flow" on the main screen or Methanol Setting. The pump should be running as you are purging. Each time you purge, the pump will run for 5 seconds. If the pump stops instantly, it means you have issues with your ground wires/ground locations. So make sure to fix it if you are experiencing this issue. Step 2: Continue to purge until the water/meth is fully spraying out of the meth line that goes into the Solenoid. Purge about a full gallon or two worth of water/meth, while maintaining minimum 30% liquid in the tank. *Do not let the tank run dry, as it will introduce air in the system, and it will no longer flow. If air gets in the pump/line, you must purge the system again. Step 3: Once the system is purged, connect the line back on the solenoid. Then, purge it through the nozzle. Make sure the nozzle is spraying like strong fine mist. Once this is confirmed, use the teflon tapes on the threads of the nozzle & mount the nozzle on the pipe. You can NPT tap the factory OEM pipe, or you can use a NPT bung if you have an aftermarket cold pipe. If you don't want to tap the piping, you can get a BMS Meth Adapter to install the nozzle.

Now you can fill up the tank with Methanol Mix (M1 Methanol ~80% content & distilled water ~20% content)

Stage4 WMI APP Settings

Step 1: Go to the Setting Tab & Select Module Mode to DCAN Mode

Step 2: Go to "Methanol Injection Setup" Input the following values and press "SEND" The app will show "SEND SUCCESSFUL" at the bottom of the screen. If it's unsuccessful, SEND again until the data is sent successful.

Step 3: Go to "User Adjustment" setting, and input the following Pump Duty values, and press SEND.

Confirm SEND Successful. (CAM Setting does not matter)

Data Logging Settings:

Step 1: Use the following Settings for your Logging & Unit Conversion. This will allow your app to automatically start logging when you press 70%+ Throttle, and it will stop the log 3seconds once your throttle is lifted below 70% input. For a proper log, we recommend going through a wide open throttle at least 5seconds or more. Please send us a log to sales@lap3usa.com for review.

Step 2: Go to the main screen and change gauges to Meth Status, Pump Duty, and Intake Air Temperature.

Go for a drive and confirm the Meth gauge showing ON under wide open throttle, and OFF during shift & when you let off. The No Fluid light is also used as Meth Status ON/OFF gauge function. It should lit up red only when it's injecting. If the No Fluid light is on all times, it's indicating Meth Injection Faults. It can mean several things. 1. No fluid in the tank and/or Air pocket is introduced in the system Solution: Purge the Air out of the system from the Pre-Solenoid meth line.

2. There is a noticeable amount of Methanol Leak Solution: Find & Fix the leak

3. Kinked Meth Line Solution: Find & Fix the kink to relieve the pressure

4. Bad Ground/Bad Power wire

Solution: Find any open circuit of the wires

As you are boosting under heavy throttle, it should activate the METH STATUS. Check the Intake Air Temperature to confirm the temperature drop. Normally, IAT(Intake Air Temperature) will sit 20-30'F over the ambient temperature while cruising. Once you activate the meth injection system, IAT will drop closer to the ambient temperature, if not lower! Once they are confirmed, you are good to go!
