https://docs.emtronaustralia.com.au/engine-management/faq/trigger-requests/index.htmlWhile Emtron supports a high number of trigger types, there is occasionally the need to add new engine types. The fastest way to get support for a new engine type is to provide Emtron directly with scope file directly from the Emtune software (exported from the Scope Utility as a *.esf file). If the vehicle has VVT (variable valve timing), please contact support for any special instructions. A cranking scope trace with cylinder 1 spark plug removed (or only cylinder 1 spark plug installed) can be helpful in identifying an approximation of crank index offset position. The cranking speed will speed up/slow down at the point of compression.Hugoen-us
