Hi

I have a problem whit my IAC stepper. Vems tune have icon sais IAC off. Is always off I see all settings not find nothing. If I go to tolls IAC lock force the unit move the IAC start too work the icon in vems tune is green. When is green the IAC work very good made everything I want if I order idle 1500 rpm go and is very steady. Disconnect the unit and connect again not work again.  I use the firmware 1.1.94, my ecu have almost 3 years the system said more than 1.1.94 is necessary lock someting.  I miss someting?
