The HKS Flash Editor is an extremely quick and simple reflash tool to use. It comes pre-loaded with 3 HKS calibrations specifically for the V3 supercharger kit 1) stock, 2) 91 octane, 3) E85. It also has an empty memory slot for custom/Pro-Dealer calibrations which can be added once the Flash Editor has been married to an ECU.
The first time you plug the Flash Editor into your ECU, you’re going to see a warm-up animation and within a couple seconds you’ll see the “home” screen:
From the “home” screen, you have the options for: ECU Read, ECU ReFlash, Car Status, and Editor Status. If this is the first time connecting the F.E. to your ECU, you’re going to want to choose “ECU Read” and on the following page, choose “Read Start”:
The screen will indicate when the read has been completed and instruct you to cycle the ignition off and back on. At this point, the F.E. is now married to your ECU. From there you can return to the home screen and choose “ECU ReFlash”
The “ECU ReFlash screen allows you to choose the calibration you’d like to reflash your ECU with. My pre-production version does not have the final calibration names, however your screen will show:
*Normal (stock calibration)
91 octane (V3 sc w/91 oct.)
E85 (V3 sc w/E85)
Power Writer (custom, can only be written to after F.E. is married to an ECU)
You’ll scroll down to the calibration you choose, once selected the screen will indicate the % of reflash completed. Once completed, the screen will instruct you to cycle the ignition off & back on. And at this point your ECU is now reflashed.
At any time in the future, you can revisit this screen to read and clear any DTCs by choosing the “Clear DTC” option.
Now that the F.E. is married and you’ve re-flashed your ECU with a HKS F.E. calibration, you can choose “Editor Status” from the home screen to view your ECU ID & serial number as well as the current calibration in the ECU.
From this point you can choose to disconnect and completely remove the F.E. from the car, or you can leave it plugged in, mount it to the dash and use it for live data monitoring while you’re driving.
From the home screen, choose “Car Status” and use the arrows to toggle up & down live data screens:
