DSP4 Switch With Pass Through OBDII Connector.

 (The pass through OBDII connector allows other devices to be used simultaneously with the DSP4 switch).

Available for 2014-16 2.8L Duramax vehicles (Colorado and Canyon pickups), EFILive's DSP4 custom operating system allows customers to switch 'on the fly' between four tunes, all stored in the ECM's flash memory. Having multiple tunes instantly accessible means changing tunes to suit different driving conditions no longer requires the ECM to be reflashed each time you choose to run a different tune. Simply build up all the tunes you need, flash the ECM once and then select your desired tune.

**Warning**
Do not flash through the DSP4 Pass through connector.
The DSP4 switch must be unplugged in order to read and write to the ECM.
