Engine calibration simulator usage info
This simulator demonstrates effects of changes to engine calibration of VW 2.0 TDi (BMM 8V, 103KW) at full load and 20°C ambient temperature. Simulations were carried out in great SW created by Russian scientists from Moscow University. All values are just for demonstration purpose!
All values are calculated automatically on-the-fly once you input all data. You need to either press ENTER or click with mouse somewhere outside input windows after you have entered desired numbers.

LIMITS
- It doesn't scale very well on mobile devices - it needs at least 1024 x 768 screen.
- While input data and calibration values are based on reality. Some results are simulation only.
- EGT values are much higher in reality - this simulator doesn't reflect heat accumulation and heatsoaking.
- All input values are linearly or bilinearly interpolated - in some cases ± 20% interpolation errors.
- moving MAP assumes correct fuelling, boost itself doesn't move pistons.
- Accuracy drops if values are too far from stock setting. Especially, below 2400 mbar.
- IAT is an estimate based on engine load, ranging from +5 to +30°C above ambient temp. Assuming IC can handle extra heat.
- SOI comp advances timing by 2°; For example factory SOI 12° BTDC or -12° TDC is 14° or -14°; during our experiments, we noticed visible engine torque reduction beyond 2° advancement.
