BitEdit VAG 7GV Screenshot 3


Software module for editing calibrations of VAG Magneti Marelli 7GV ECUs.

The following maps are available for editing:

  • Injection timing, injection correction depends on temperature and injection at start.
  • Idle engine speed in all available modes
  • Friction and drag torque control, indicated torque control, relative and requested torque at different conditions, full load torque limitation, slow down torque, power limit torque and more…
  • Knock control sensivity, spark advance correction, maps to detect good/bad fuel
  • Rev limiter (engine speed limiter)
  • Exhaust gas model: temperature and pressure calculation and corrections
  • Calculation of airmass, compression ratio, air density values, correction of airmass
  • Spark advance, base, optimal, minimal angles, correction of advance
  • Target lambda in part load, full load, WOT mode, combustion efficiency by lambda
  • Speed limitation values
  • Throttle valve target position maps, mechanic law of throttle valve, maximal request of position
