Tuned from thefirmware up
Developed by reverse engineering the factory logic from scratch to create a unique tune. All the power of a tuned engine but with the original BMW refinement still intact.

Benefits of a CAFlash DME tune
The power delivery stays as smooth and progressive as the factory calibration, at the output of a tuned map. That is what separates these tunes from the others available on this platform.
01 / Delivery
Stock smoothness, tuned power
Torque arrives progressively and predictably, with no surge in the middle of the rev range like other tunes. Factory delivery characteristics at tuned power levels.
02 / Fixes
Fixing common tuned N54 problems
All my tunes incorporate fixes for the common surging issues that users experience at part load.
03 / Character
Torque ramps and OE-level burbles
Torque ramps adjusted to suit how the car is driven, and overrun burbles built from factory logic.
04 / Driveline
6AT and DCT optimisation
The transmission is calibrated alongside the engine map, with separate optimisations for the 6-speed automatic and the DCT.
05 / Hardware
Built for modified cars
Full access to the tables covering deleted air conditioning and electric engine fan systems, so a stripped car runs properly instead of dropping into limp mode.
DCT · Transmission
GTS DCT software on an N54!
A conversion of the BMW M3 GTS (CRT) transmission logic to support N54 equipped vehicles. With support for the 135i, 335i and Z4.
01 / Source
Ported from the M3 GTS
The M3 GTS (CRT) transmission software, converted for use with the N54 engine.
02 / Shifts
Faster in both directions
Upshift and downshift speed improved across the range, with noticeably more accurate rev-matching on the way down.
03 / Refinement
Smoother in normal driving
Shifts are smoother at low load and more accurate at high load, which reduces transmission wear and reduces the chance of traction loss during shifts.
04 / Fixes
Common DCT complaints addressed
Hesitation pulling away at junctions and other well-known DCT complaints are dealt with as part of the rework.
