SOCAL DSP4 Switch 90 Degree

In stock

DSP4 Switch with 90 Degree OBDII connector.

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 using the EFILive tuning tool, flash the ECM, plug in the SoCal Diesel DSP4 switch and switch tunes on the fly.
