BMW 320i B48 184PS 2.0 Turbo Tuning Box – Bluespark Pro Plug & Play Piggyback ECU Power Module for F30/F31 3 Series | Petrol Chip Tuning Stage 1 Style Map Box | No-Remap Flash-Free Performance & Throttle Response Upgrade

BMW 320i B48 184 PS Plug-in Petrol Power Module by Bluespark

Give your F30 or F31 3 Series the punch it deserves with this plug-in engine control upgrade from Bluespark. Tailored for the 2.0 B48 petrol turbo 184 PS 320i, this external ECU module sharpens throttle response, boosts mid-range pull and delivers stronger in-gear pace without opening the factory computer. A simple loom connection transforms day-to-day driveability while keeping the car fully reversible.

We have installed and run this unit on multiple B48 320i cars and the results are consistently impressive. Customers report smoother delivery, earlier torque, cleaner overtakes and a more eager feel across the revs. It is a smart, flash-free route to performance that you can feel every time you press the pedal.

Why this power module works so well

• Dual channel architecture interfaces with key sensors for optimised boost and fuelling signals
• Selectable calibrations let you tailor the gain from subtle improvement to maximum punch
• Premium loom with OEM-style connectors for a neat, secure, plug-in install
• Fully reversible, no ECU flashing, ideal for warranty-friendly use once removed
• Durable aluminium enclosure designed for the engine bay environment
• Compatible with automatic gearboxes, semi-auto systems and start-stop
• Potential economy benefit when driven gently thanks to stronger low-down torque
• Backed by a 2-year manufacturer warranty and 28-day money-back guarantee

What you will feel on the road

• Stronger surge through the mid-range for confident overtakes
• Quicker response off the line and out of junctions
