E-gas idle control
 

How is the idle controlled on an e gas cars (electric throttle body). Is there a pre set screw set from the factory and then pluged or is it all computer controlled threw the dme software ? Than you all..!

There is an idle control valve (solenoid) directly mounted to the throttle body, controlled by DME for both e-gas or cable throttle cars. It basically bypasses air across the main throttle valve to keep consistent idle speed under various conditions.

On E gas engines, the DME controls the idle speed via software.
