BMS (Burger Motorsports): Intelligent Power Without Warranty Worries
In the tuning world, there is an eternal dilemma: gain more power or keep the factory warranty and reliability. BMS (Burger Motorsports), founded by Terry Burger, solved this equation once and for all. Their legendary JB4 Tuner is not just a simple "boost box." It is the world's most advanced parallel engine management system (Piggyback) that transforms your BMW, Kia Stinger, Infiniti Q50, or Supra into a rocket without rewriting the car's ECU software.
ATOMIC-SHOP is an official dealer of Burger Motorsports. We offer the full range of solutions: from JB4 tuners to cold air intakes, intercoolers, and accessories. It is the #1 choice for those who want +100 HP in 30 minutes, installed right in their own garage.
The JB4 Revolution: More Than Just a Chip
Most cheap tuning boxes work primitively: they simply trick the MAP sensor into thinking boost is low, forcing the turbo to work harder. This is dangerous because the ECU is blind to the real conditions.
The JB4 is different. It is a full-fledged computer that connects not only to sensors but also to the vehicle's CANbus. This allows it to see hundreds of parameters: RPM, throttle position, temperatures, Air/Fuel Ratio (AFR), and knock data.
Because of this, the JB4 manages the engine intelligently:
— It won't increase boost until the oil is up to operating temp (Cold Oil Protection).
— It automatically lowers power if it detects knock or a lean mixture.
— It allows you to limit boost in lower gears (Boost by Gear) to maintain traction.
The Tech Battle: JB4 (Piggyback) vs. Flash Tune
This is the most common question. Which is better: install a JB4 or flash the ECU (like MHD or Bootmod3)?
| Feature | Flash Tuning (ECU Reflash) | BMS JB4 (Piggyback) |
|---|---|---|
| Operation Principle | Rewrites the factory software inside the ECU. | External Module. Intercepts and corrects signals without altering factory software. |
| Dealer Warranty | High Risk. The "Flash Counter" changes; dealers can see the modification immediately. | Safe / Stealth. Can be removed in 20 mins before service. Leaves no trace in the flash counter. |
| Map Switching | Usually requires stopping and reflashing (or cruise control hacks on expensive suites). | Instant. You can switch maps using steering wheel buttons while driving. |
| Resale Value | Low. Licenses are often VIN-locked (money is lost when selling the car). | High. Remove the JB4, sell the car, and sell the tuner separately or move it to your next car. |
Control from Your Phone: JB4 Mobile
One of the best features of BMS is the Bluetooth Wireless Connect Kit. It turns your smartphone into a command center. Through the JB4 Mobile app, you can:
- Datalogging: View graphs of boost, timing, and AFR in real-time. This is a professional diagnostic tool.
- Read Codes: The JB4 acts as a code scanner, allowing you to read and delete check engine codes on the fly.
- Customize Maps: You can create your own custom map (Map 6) for specific fuel or weather conditions.
More Than Just a Chip: The BMS Ecosystem
Burger Motorsports knows that software needs hardware support. They produce components to help the engine handle the new power:
1. BMS Performance Intakes
BMS intakes don't just add 10-15 HP; they unleash the sound of your turbo. That coveted "whoosh" sound (spool and blow-off noise) becomes audible thanks to the open filter design, enhancing the driving experience.
2. Charge Pipes
A weak point on modern BMWs is the plastic pipe from the intercooler to the throttle body. Under increased boost, it often cracks or explodes. BMS aluminum charge pipes are a mandatory reliability upgrade.
3. Oil Catch Cans
Direct injection engines suffer from carbon buildup on valves. A BMS Catch Can filters oil vapors from the PCV system, keeping your intake clean and extending engine life.
Frequently Asked Questions (FAQ)
Can I install the JB4 myself?
Yes! This is the BMS philosophy. 90% of their products are designed as Plug-and-Play. You don't need to cut wires or solder. The kit comes with OEM connectors that plug in-line with factory sensors. For most cars (BMW F30, Kia Stinger), installation takes 30-60 minutes in a driveway.
What are "Map 1", "Map 2", "Map 5"?
These are pre-configured power maps:
Map 1: Safe tuning for a completely stock car (+40-60 HP).
Map 2: Aggressive map for cars with downpipes and intake (Stage 2).
Map 5 (Autotuning): An "intelligent" map that adjusts itself based on fuel quality and weather. The favorite choice for daily driving.
Does JB4 support Water/Methanol Injection (WMI)?
Yes, and this makes it unique. The JB4 has a built-in methanol controller (FSB integration). It can control the pump and solenoid based on boost pressure. Furthermore, if the methanol runs out or flow stops, the JB4 will automatically switch to a low-boost safety map, saving your engine. You don't need to buy a separate controller.
