BMW Z4 G29 2018-on Performance Upgrade Module — Non-Bluetooth

Transform your BMW Z4 G29 with a premium plug-in performance module designed to deliver serious gains without a risky remap. This non‑Bluetooth unit optimises engine signals from the factory control system to unlock power reserves safely and reliably. Ideal for drivers who want stronger acceleration and effortless overtaking while keeping OEM safeguards intact.

Why owners love this upgrade

• Power and torque increase of up to 30 percent within factory tolerances. Feel the extra shove in the mid‑range and smoother pull across the revs. Figures are estimated and vehicle dependent.
• Improved fuel consumption potential. With torque available earlier, upshifts can happen sooner which can mean up to 1 litre less fuel per 60 miles. Savings are indicative based on RaceChip research.
• OEM safety retained. Factory protective strategies remain active, plus enhanced protection features built into the unit for added peace of mind.
• Fast, reversible install. Plug‑in fitment typically takes 10 to 15 minutes with no permanent changes, a great remap alternative for leased or warrantied cars.

Engine safety and reliability

• Engine Protect System+ and warm‑up timer help ensure performance is delivered responsibly once operating temperatures are reached.
• Seven fine‑tuning maps allow vehicle‑specific optimisation for your Z4 roadster.
