Burger Motorsports JB1 Stage 1 Tuner (Type B TMAP) for BMW N20 N26 N55 S55 – Plug & Play Tuning Box | M2 Competition, M3 F80, M4 F82, M135i, M235i, 335i, 435i (2014+)

JB1 Stage 1 Plug-in Power Module for BMW N20 N26 N55 S55 - Type B TMAP Harness

Turn your F-series BMW into the car it should have been from the factory with the JB1 Stage 1 piggyback module. This simple plug-in power box sits between the factory sensors and the ECU to deliver stronger mid-range pull, quicker throttle response and a serious hit of torque without a flash remap. Expect a noticeable reduction in turbo lag and OEM-smooth drivability, all while retaining factory drive modes and a fully reversible install.

We run this upgrade ourselves and our customers consistently report how much more urgent and responsive their cars feel on the road. If you want a cost-effective performance boost that fits in minutes and can be removed just as easily, the JB1 is the go-to solution.

Highlights

• True plug-in module with a neat Type B TMAP loom for late F-series platforms
• Integrates with the stock management for smooth, repeatable gains
• High-speed 64 mhz processor sampling around 800 times per second with dedicated 10-bit converters for ultra-refined control
• Automatically recognises N20, N55 or S55 via TMAP voltage and optimises mapping
• Invisible install inside the engine bay and fully removable for servicing
• Factory driving modes retained and no coding required
• Economy remains as stock during light throttle cruising

Expected gains

• N20: up to 45 hp and 60 lb ft
