Introducing the G80 Boost Launch Harness, your ultimate solution to unlocking unparalleled acceleration 🚗💨 off the line without the hassle of sketchy Facebook pay or searching for availability through random Facebook posts. Designed for speed enthusiasts seeking to elevate your launch game and slash your dig and quarter-mile times without breaking the bank on TCU or ECU tunes.

Why choose the G80 Boost Launch Harness (BLH) versus through a Facebook Post?

This BLH has the potential to be compatible with any turbocharged vehicle equipped with a Micro 2 Break Switch fuse or Break Lamp fuse, similar to other prevalent Hyundai/Kia models like the Stinger or Kona. However, this BLH is specifically customized for the G80 Sport platform by an actual G80 Sport user while offering comprehensive instructions for both installation and operation tailored to this particular vehicle.

Tailored for the G80 Sport:

• Length is optimized to minimize excessive slack while providing adequate strain relief

• Optional BLH Switch Backshell upgrade available, coming soon

• Optional G80 Boost Launch Harness Fuse Box Cover upgrade available, coming soon

• Detailed how-to-use and installation instructions based on the G80 Sport platform

• BLH uses a Micro 2 connector as required by the G80 platform

What is a Break Boost Launch Harness?

When applying the brakes on your vehicle, your RPM’s are limited making it impossible to build boost at launch. With this harness, you are now given the ability to switch this restriction ON or OFF. While in the OFF position, you are now in control of how much boost you are delivering to your engine.

Quality & Support:

Every BLH undergoes a continuity and isolation (C&I) check and Pull Tested prior to shipping. By doing so, guaranteeing electrical and mechanical integrity ensuring optimal performance and durability while adhering to industry standards. All splices, if any, are soldered Lap Splices with waterproof isolations and heat-shrinked.

Unlike a fleeting Facebook post, Zacarias Engineering is steadfast and accessible for inquiries and support, ensuring reliability and peace of mind for our customers.

Cost-Effective Performance Enhancement:

Unlike costly TCU tunes or invasive ECU modifications, this BLH offers a more economical alternative. With our harness, you can achieve remarkable performance gains without emptying your wallet.

Plug-and-Play Convenience:

Installing the BLH is a breeze, thanks to its simple plug-and-play design. No need for complex wiring or technical expertise—simply connect the harness to your vehicle's existing fuse box (BREAK SWITCH fuse location), and you're ready for those gains. Plus, you can revert to stock settings or remove the harness whenever desired.

How does it work?

Page 7-65 from your Genesis G80 Manual (2018) or rear side of fuse box cover shows the fuse box diagram where you’ll find the “BREAK SWITCH” fuse position with a 10-amp fuse (Not to be confused with the Stinger “STOP LAMP” fuse position, different function). During normal stock use, this circuit communicates with the ECU and is a complete circuit. One of the functions of this circuit is to communicate to the ECU when you have applied your vehicle brake pedal. When applying your brake pedal, the ECU will limit the number of allowable engine revolutions or RPM’s. Resulting in the inability to build boost during launch.

By adding a switch to this circuit, you are now given the ability to remove this RPM limitation from the ECU by masking your brake press. Resulting in the ability to build boost during launch.

Note that on Stinger platforms, a STOP LAMP fuse is used which will disable your brake taillights. This does not occur on the G80 Sport platform.

Boost Launch Harness (BLH) ON and OFF Switch positions:

• “1” or “ON” position, the circuit is complete, ECU registers when the brakes are applied.

• “O” or “OFF” position, the circuit is incomplete, ECU does not register when the brakes are applied.

How to use your BLH for a boosted launch?

1. Deactivate the Electronic Stability Control (ESC) System: State 2 -

   1. Press the ESC OFF button for more than 3 seconds. “ESC OFF” indicator icon will illuminate on dashboard and ESC OFF warning chime will sound. At this state, the engine control function and brake control function do not operate. Page 3-98 & 5-49, Genesis G80 Manual (2018).

2. Activate SPORT Mode -

   1. Press the Drive Mode button twice. “SPORT” indicator Icon will illuminate on dashboard and SPORT mode is active. At this stage, after accelerating and releasing the accelerator pedal, the gear and engine speed RPM may not drop as soon as in NORMAL mode. Page 3-101& 5-56, Genesis G80 Manual (2018).

3. Switch Boost Launch Harness (BLH) to the OFF position -

   1. Press the “O” or “OFF” side of the BLH Switch. At this stage, the engine or ECU does not register when your brake pedal is pressed.

      1. WARNING: When continuing to drive after initial launch, the ESC icon, above the ESC OFF icon, will illuminate after or soon after the initial launch. At this stage, the engine may not respond to the accelerator as it does under routine conditions and engine RPM may not increase even if you press the accelerator pedal deeply. This is to maintain the stability and traction of the vehicle and does not indicate a problem. Page 5-48, Genesis G80 Manual (2018).

4. Build Boost and Launch! The Learning Curve –

   1. Forcefully apply and hold the brake pedal to its maximum pressed position.

   2. Apply pressure to the accelerator pedal to initialize boost build by increasing engine RPM (shall not exceed over 2,700 RPM to avoid engine failure) within a period of 1 second or less followed by IMMEDIATELY releasing the brake pedal and fully pressing the accelerator pedal for Wide Open Throttle acceleration.

      1. CAUTION – SERIOUS INJURY OR DEATH RISK:

         1. Only experienced drivers shall use!

         2. Maintain a forceful or firm grip on the steering wheel at all times. Failure to do so may result in loss of control, leading to serious injury or death.

         3. Prevent tire spin by manually shifting gears as required. Improper handling may cause the vehicle to lose traction, resulting in accidents with potentially fatal consequences.

         4. Exercise extreme caution and adhere strictly to safe driving practices to minimize the risk of harm to yourself and others.

      2. CAUTION – VEHICLE AND ENGINE FAILURE RISK:

         1. Excessive boost pressure may result in severe engine damage, including detonation, engine failure, or overall vehicle malfunction.

         2. It is crucial to understand that the user assumes full responsibility and bears sole accountability for any related damages, injury or death.

      3. Note to user: Performance gains are user or driver dependent with an expected Learning Curve. Practice under safe conditions and within a closed safe non-public environment is expected. See full disclaimer.

5. Return to normal driving condition after Initial Launch –

   1. Bring the vehicle to a complete and safe stop.
