I want to make an variable intake manifold with stepper motor using the stepper driver. Just to get 15 cm of variable longitude with ITB's, Want to get a torque peak from 6500 to 7500.
It should work like this: When the v3 starts it sets the reference position for long and when the revs increase above 6500 rpm it starts to shorthen and when rpm reaches 7500 it sets short position. It isn't a problem if the stepper couldn't move so quick because if rpm moves the slowest then the power is most significant there where the plus 20 Nm can make diffrence on the track and laptime. |
