Looking for assistance in using KIVA

I am new to KIVA and appreciate if anyone could provide assistance. We are trying to perform simulations for CI engine. However, ignition did not occur. While I adjusted cf1 in itape5 (increasing it), combustion seems to occur, however, the pressure and heat release are both now too big. Anyone can help me on this?
Thanks a lot. |

Could be many things. For example too small fuel quantity to notice the effects, or too high tcut or tcute in itape5.
