Changing the settings in EQMOD is pretty simple once you calculate the figures you need. Start EQMOD Toolbox & click on the "Driver Setup" button. That opens the settings screen. In the top left corner change it from "Auto Detect" to "Custom" then click the spanner icon that appears. That opens the box for the ratio settings. Now you just need to calculate the correct data to enters. The bottom half of this page details how to do that.
