v5.1 - recommended

v5.1 has massive inner changes. New task scheduler was developed, to achieve smoother and deterministic operation. Many speed optimizations were applied. As a result - main cycle calculation time was reduced from 800us to 450us.

What's new:

  • 3D PWM table
  • new algorithm for fuel pressure and temperature corrections
  • VVT: completely redesigned, with better stability, precision, error detection
  • Boost: pressure limit by external 0-5V signal
  • Traction: AWD mode
  • Traction: Separate min throttle settings for high and low load
  • Separate RPM limit for neutral gear
  • RPM limiting with throttle
  • Idle stabilization improved


  • BMW high pressure Vanos control (S62 engine)
