BMW F80 M3 Remapping


Here at GAD Tuning we invest heavily in having the latest calibration software, dyno cell test facility, main dealer diagnostic tools and communication tools to make the very best and safest calibrations for your BMW M3. We spent hundreds of hours testing calibrations and monitoring results with many cars including BMW M3s all over Europe through other clients.

The BMW F80 has the latest Twin-Turbo power plant designated as the S65 engine which is a 3.0 Litre inline 6 cylinder with two turbo chargers couple with a really efficient water to air charge cooler. Running the latest Bosch MEVD17.2.

We first start by getting your BMW M3 in the workshop and run full diagnostics of all systems in the vehicle. This will give us a clear indication to weather we proceed with the recalibration and dyno process or not. After getting the all clear we actually do something that many tuning firms do not do and that's to get the BMW M3 in the Dyno cell and peel off a lot of residual heat from the drive to us. This means that we wont be battling temperatures and skewing results. This will give us accurate and repeatable results to get a good base line for what we are working with.

From this the calibration process begins and we pull stock OEM data from the vehicle and start the calibration process. This can take a few hours with many calibrations and multiple sweep tests and steady state load testing to get the most from your BMW M3 safely. Only after data logging multiple channels and analysing the data we settle and what we think is the safe power and torque output of your vehicle.

Things monitored while tuning your BMW M3:

Along with increasing the performance of your BMW M3 we can also offer a plethora of coding updates due to the hardware being shared with many models. Including...
