Step One: Reading Out The Stock Program

1. Plug the AutoCal into the truck’s OBDII using supplied cable.
2. Turn the key to the on position (do NOT start the truck)
3. Scroll down to the ‘Tuning Tool’ and hit ‘OK’.
4. Select the ‘Read Tune’ option.
5. It’ll say Hit ‘OK’ on the appropriate ECM/TCM for your truck (CMB: 2006-07 5.9L, CMC:2007.5-09 6.7L) and will begin reading the stock file from the truck.
6. When it finishes reading out the stock file, the AutoCal will prompt you to turn the ‘Ignition Off Now!’. Turn the key off and press ‘OK’. Once the countdown completes, you can proceed to Step Two: Flashing the Tune File (below)

Step Two: Flashing The Tune File

2. Turn the key to the ‘RUN’ position, do not start the truck.
3. Toggle down using the right (skull) button until you see ‘Program Full’ (under the ‘Tuning Tool’ option in the main menu) . Press the ‘OK’ button (skull) in the center of the AutoCal.
4. It will say ‘Read’…Toggle down to your tune file (will be either CSP5 or a single hp tune) & press ‘OK’ the screen will say ‘Checking to 100%’.
5. It will ask if you want to ‘LICENSE ECU NOW’ (will only be displayed the first time you flash the truck with your AutoCal/V2). press ‘OK’.
6. It will now ask ‘Are you sure?’. Press ‘OK’.
7. The AutoCal should now say ‘Please Wait… Erasing… Flashing’ with a percentage (%) below it. The flashing process takes approximately 13 minutes.
8. When the flashing has finished and it reaches 100%, the AutoCal will prompt you to turn the ‘Ignition Off Now!’. Turn the key off and press ‘OK’. Once the countdown completes, you can disconnect the AutoCal from the OBDII port, and start your truck! (**Note: Be sure to replace any fuses that were removed prior to the tuning process!**)
