INSTANT POWER GAIN WITH NO DOWNSIDE!
Max HP gain up to = 17 hp
Max Trq gain up to = 11 ft-lbs

Years of S54 tuning for both street and track cars, including a strong relationship with Bosch Motorsport, has allowed us to offer an excellent tune package for the Z4M driver that appreciates a comprehensive tune that's suitable for a daily driver. Totally streetable on 91 octane fuel (with performance gains you can feel), the Turner Z4M tune really comes alive from the middle of the RPM range and pulls stronger directly up to fuel cut at redline. Throttle response is crisper and more direct throughout the entire range of motion of the pedal. All of these benefits, and Turner still retains all factory emissions controls. Offering:

  • fuel and timing maps at part throttle and wide-open throttle
  • revised torque settings and knock control
  • improved VAN0S variable valve timing
  • smoother and faster pedal response
  • top speed limiter raised (180mph)

Our software is installed via the Turner flashing OBD tool. This tool plugs into the OBD socket in the dash and the performance software is installed from a laptop computer connected to the tool. It also works as a fault code scanner to read and reset diagnostic trouble codes and reset adaptations. The software program requires a Windows XP/Vista/7/8/10 laptop and the installation and setup are very easy (click here for instructions). The OBD tool, cable, and installation files are shipped to you with simple setup instructions. Files are exchanged with our calibrators via email, resulting in no downtime for your vehicle. There is no need to remove your ECU and ship it. You can have your Z4 flashed from the convenience of your garage or driveway!

Looking to maximize your power gains and an excellent complement to our tune? Add a Turner IAT Relocation to combat power-robbing heat soak - the only true plug-and-play solution available. Heat soak is a real plague on consistent power for a stock or tuned vehicle. We recovered 11lb-ft torque at 2500rpm through use of our relocation kit. Here are the heat soak-related torque losses we experienced (in an E39 540i):
