EFI Live Custom Operating Systems

Installing a Custom Operating System with EFI Live requires a full operating system re-flash of the Controller into which the Custom Operating System is to be deployed. Full re-flashing is only available with FlashScan V2 Scan and Tune, and FlashScan V1 Commercial options. However, you can tune any pre-installed EFILive Custom Operating System with FlashScan V1 Personal version. Of course, your FlashScan interface needs to support the vehicle you wish to install your chosen Custom Operating System on.

Gen-IV (E38 & E67) Gasoline Custom Operating System

E38 and E67 custom operating systems offer the following features.

2 or 3 bar custom operating systems are not required for these controllers as the standard GM operating systems are designed to support forced induction motors. EFILive has successfully mapped these features into our Virtual VE table.

Gen-IV (E40) Gasoline Custom Operating System:
2.5 bar Forced Induction extends the fuel tables to allow the PCM total control over fuel all the way to full boost. EFILive retains the standard fuel for non-boost conditions retaining factory drivability and adds new tables for boost control. Extend Cooling Fan operational range allows users to turn on cooling fans below factory limits. The E40 custom operating system also features Anti-Theft (VATS) disable.

Gen-III Gasoline Custom Operating Systems:

Diesel Custom Operating Systems
DSP² - Duramax Switchable Program² – suitable for LB7 and LLY Duramax
DSP² allows users to switch on the fly between 2 tunes that you create. In addition to applying EFILive’s DSP² custom operating system, users need to install a Single Throw Toggle switch to the ECM.

Users can change a selected range of parameters that include Boost Levels, Injection and Timing – the key parameters to gain performance or economy from your multiple tunes. DSP² also has 9 user definable thresholds that will switch an ECM controlled output; parameters include Boost Levels, RPM, Throttle Position. These output could be used to control such things as Shift Lights, Warning lamps, Water injection, or N2O cut (throttle must be above 90% etc).

DSP5 - Duramax Switchable Program 5 – suitable for LB7 and LLY Duramax
DSP5 is similar to DSP², except the number of switchable tunes has expanded from two to five. An Advanced Staging option is also included. In addition to applying EFILive’s DSP 5 custom operating system, users have the option to either install a 5 position resistance switch, or switch tunes via the FlashScan V2 interface. Switching via FlashScan V2 eliminates the need to install a 5 position resistance switch. The user can even name the tune to be displayed on the V2 interface for easy reference.

The Advanced Staging option allows users to limit fuel delivery amounts which in turn allows you to control (or limit) power under certain conditions. This function is useful for drag race staging by allowing you to launch at consistent RPM or boost levels without trying to control the throttle manually.
