EMS4 w/90 ISC Valve
 

Do you guys use your stock ISC valve with the EMS4? I ran a GPIO5 wire to mine with a 12V power wire and it resets the AEM every couple of seconds if I power it up. If I unplug the connector to the ISC its fine. AEM states the EMS is only compatible with a pulse width style valve and not a stepper. Not sure if this has anything to do with it?
