Issue

after installing the ecu tune the car ran great. Then started feeling like the boost was leaking or cutting out that’s when I upgraded the Mac bov solenoid. I have not done the ebcs yet but if this is a part I need for the tune to run better it should have been mentioned when buying the Tune. I feel like the boost cuts out alot and most of the time feels like the car Isn’t even tuned anymore? I will buy the ebcs and try that to see if it helps but if not I will be very disattified. I have had a boost gauge in car from beginning. Car ran around 16 psi stock. Then went to 23 when tune was installed now I can’t get it up to 23 anymore. Car is back running 16psi and feels stock tuned. Hoping this ebcs solves the problem. Any advice thanks?

  • Tools Needed - Large Zip Ties - 8-10mm Sockets - Electrical Tape - Velcro Tape - Android device with Google Play Store access. Installation Time: ~15-30min depending on experience. Sensor Location reference picture: Step 1: Disconnect the battery Step 2: Locate the section of cable labeled "MAP" from the ProTuner main harness. Disconnect the factory MAP sensor plug, and connect the Pro-Tuner MAP sensor cable. Step 3: Locate the Y-cable labeled as "CRANK" from the Pro-Tuner box. Disconnect the factory CRANK sensor cable, and connect the Pro-Tuner CRANK sensor cable on each end of the factory plugs. Locate the matching plug from the Pro-Tuner main harness and connect the other end of the crank cable. Step 4: Locate the section of cable labeled "BOOST" from the ProTuner main harness. Disconnect the factory BOOST sensor plug, and connect the Pro-Tuner BOOST sensor cable on each end of the factory cable. *Note: The BOOST map sensor is located on the pipe before the throttle body, and it looks just like the Map sensor you connected on the Step 2. Step 5: Locate the CANbus cable from the Pro-Tuner and connect it to the CANbus port located next to the engine by the passenger side. Use electrical tapes to secure the connection. *Note: If your vehicle model is the Elantra GT Sport, please see the next step. Step 5: For the Elantra GT Sport models, the CANbus port design is slightly different, and you must position the CANbus plug one slot to the right, in order to make proper connection as shown in the photos below. Use electrical tapes to secure the connection. Step 6: Locate the Bluetooth Module from the Pro-Tuner box, and connect it to the matching plug on the Pro-Tuner harness. Step 7: (Optional Speed Limiter Canceler(Green Wires) - Coming Soon) Step 8: Use electrical tapes on each end of the Blue & Green wires as they are not used. Step 9: Locate and connect the power wire from the Pro-Tuner to terminal location inside the fuse box. Step 10: Connect the main harness to the Pro-Tuner ECU. Use Velcro fastener to mount the Pro-Tuner ECU & Bluetooth module on the desired location under the engine bay. Step 11: Connect the Battery Step 12: Grab your Android device, install PROSS app from Google Play store. (V1 Pro-Tuner App Link: UNCLE CHIP PRE for Android - APK Download ) (V2 Pro-Tuner App Link: LAP3 V2 PRO-TUNER PROSS BT APP ) Start the car and pair the device through the Bluetooth Setting. When you open the app, it will ask you for serial#. The Serial numbers are located behind the Bluetooth module. Once its up and running, confirm the 3 indicators (Bluetooth,OBD2,Uncle Chip) on the app are RED. Step 13: Select the ECU CONTROL MODE button and to choose your mode. V2 Pro-Tuner Mapping : Mode 1 - Stock Map Mode 2 - 92+ Octane Mapping Mode 3 - 93+ Octane Mapping Meth Mode - Meth Mapping(80% WMI with a 400~500mm Nozzle. Injection Start between 5-10psi & Max Spray @ 15-20psi) or (3-4 gallons E85 mix or Race Fuel mix) User Mode - 91 Octane Mapping, which can be customized by the user V1 Pro-Tuner Mapping : Mode 0 - Stock Map Mode 1 - 91-92 Octane Mapping Mode 2 - 93 Octane Mapping Mode 3 - E30 Mapping (Requires 4 gallons of E85 and topped off with 91-93 octane) *If you plan on running Mode 3 without E30, you can run Methanol Injection with a 400-500mm Nozzle. (Injection Start @ 5psi & Max Spray @ 15psi) Step 14: Enjoy!
