|
|
* Here we have two auxilary digital on/off outputs which would open once per each 360 degrees of engine crank revolution.
|
|
* The second valve is 180 degrees after the first one.
|
|
*
|
|
* Valve open and close angles are taken from scriptCurve1 and scriptCurve2 tables respectively, the position depend on TPS input.
