VAFC tuning step by step

Step 1: From the main menu, go to the  "settings" option

Step 2: Once in the "settings" menu you will see the following options. To adjust your fuel settings, you will need to adjust both the "wide-thr" and the "narr-thr" options. Let's start with the wide throttle (WOT) option

Step 3: Upon selecting the wide throttle option, the following screen will appear. This is where you tell the VAFC how much increase or decrease in fuel you want compared to stock settings. My setup as shown is compensating for the extremeley rich Mugen P28 ecu that I have. This screen is only for the WOT range, and also, for the lower RPM range. VTEC is represented by the light vertical line. Move the point of adjustment to the right and adjust your fuel at each rpm point with the up and down arrows. Now, let's adjust the WOT hi rpm range by hitting the "next" button
