Lap3 Uncle Chip

I’ve been running my chip on 93 for about 2 months now and have loved every second of it. Highly recommend, I can definitely feel a difference.

  • What can I say.... A very good quality product and easy install. I also took the opportunity to also install brand new plugs and replace the old batch of HKS M45XLs. After 3+ years of wait, my ‘15 LF has finally awaken. Setup and configured to ECU Mode 2. Better throttle response, no lag whatsoever. I'm running no cats, straight-pipe, 0W-40. Tested both city and highway speeds with traction control off. (was so excited, I didn’t focus on taking a video). Received the product last Monday and waited until today to perform the install and not rush it. Kudos to David Chung and the team at Lap3 Performance. Definitely worth it.  Here’s a couple of pictures of the installations including some tips on how to make your install as easy as possible. a. CANbus port image on installation guide is beside the fuse box and text states CANbus is located on the passenger side. This may be taken from two different vehicles... probably passenger side CANbus is from Hyundai models and driver side CANbus is from KIA models. As on my install, the CANbus is on the passenger side. No biggie as the CANbus port is really not hard to locate. The LAP3 harness for the CANbus was routed and zip-tied along with the hoses for my LAP3 OCC. b. For those who have AEM CAI installed, the easiest way to access the "CRANK" sensor is to remove the filter and heat shield assembly. Be careful to not drop the screw closest to the BOV when removing the heatshield. (it almost fell for me). c. The LAP3 harness connected to the "CRANK" sensor was routed at the back under the brake fluid master cylinder and behind the car's ECU and zip-tied to other factory harnesses. d. If you were to route your LAP3 harness above or below the charge pipe or, even just above the cold pipe that leads to the throttle body, be careful not to let your LAP3 harness come in contact as it may not be long before the harness melts from contact under extreme heat. I chose to route my install above the cold pipe and above the charge pipe. IMO, easier to adjust or make changes even when engine's hot. e. You will notice that the sticker on the bluetooth module has been peeled of the back and transferred to the top as I have installed velcro straps to the bluetooth module on top of the fuse box. It will be easier to pair in case I change phones. (just a personal preference). I may relocate the bluetooth module inside the car and routed through the firewall when I get the chance. f. Once your install is done mainly on the CANbus, MAP, BOOST and CRANK, I zip-tied the remaining harness and placed it just in front of the battery. (some would place it just to the right side of the battery. this is just your personal preference.) Hopefully I'll be able upload videos soon. Feel free to post any question you may have on LAP3 facebook page or in this forum. Goodluck, enjoy and LAP3 FTW.
  • 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 CRANK sensor underneath the factory charge pipe. Find 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. Note: The Crank sensor is underneath the factory charge pipe. You can remove the factory airbox to access it. 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. Note: The BOOST sensor is located on the cold pipe just before the throttle body 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. 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. (Link: UNCLE CHIP PRE for Android - APK Download ) 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. Mode 0 - Stock Map Mode 1 - 91-92 Octane Mapping Mode 2 - 93 Octane Mapping Mode 3 - E30 Mapping (Requires 4-5 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 500-600mm Nozzle. (Injection Start @ 5psi & Max Spray @ 15psi) Step 14: Enjoy!
