Base idle set screw Evo


Recommended Posts

On the EVO as it is a stepper motor you will actually have to make sure the air bypass has been blocked off.

The engine should be able to hold a slightly lower than normal idle when warm.

In the ISC BASE POSITION table (% DC or Steps) put the lowest value possible.

Correction, the numbers in the base position table when using a stepper motor  are "steps from fully open".  Therefore a smaller number is more open, a large number is more closed.  Put something like 500 in the whole table will close the valve.
