EFI Live 01-10 Duramax Spade Tune Loading Instructions

How to flash your 2001-2010 Duramax

  • Make sure you have been provided with or read off your stock file(s) before proceeding
  • In order to install your tune, you will need the following items: SPADE, and OBD2 cable.
  • Please remove your electronic boost fooler and pressure box if you have one installed on your truck. It will negatively affect your truck's performance with our product.
  • Turn off or remove any aftermarket electronics. These can interrupt the flash process and cause tune loading issues.
  • Turn off auto headlamps and dome lights while flashing.

 

For 2001-2005 Trucks the following fuses under the hood should be removed prior to flashing to avoid voltage issues:

  • Radio
  • Radio amp
  • Info/infotainment(not every truck will have this one)
  • HVAC(some trucks will have multiple)
  • 60amp ABS
  • Lift pump
  • Remote start (some installers will steal power from the OBD2 port, this would need to be disconnected prior to flashing)
  • Anything else aftermarket(subs, navigation, steps, etc.)

A battery tender/ charger can be used during the flash as an added safety

 

To put your truck back to stock follow the same process, but select your "Stock" files.

ECM Tune Installation:

10. The first time you load the tune your SPADE will ask you “License ECU?”. Press , and when you are asked “Are you sure?” Press again.

12. Once the flash is complete. Turn the key into the off position, and press X.

DO NOT turn the vehicle ignition on until the countdown timer expires.  This time is critical to allow the ECM to perform internal functions after a read or write operation.

The DSP5 switch can be installed before or after the tune is flashed. It is good practice to test that the truck runs prior to loading the tunes once your switch is installed. If your truck does not run, please check your ECM connections.

If your tunes are loaded before you install your switch the truck will default to the Optimized Stock tune.

Your tunes are in the following positions:

1. Optimized Stock

2. Heavy Tow

3. Light Tow

4. Street

5. Sport/Max Effort
