A departure from traditional Holley EFI transmission control, the Terminator X Max ECU allows the ability to use 2007+ GM 6L80E and 6L90E transmissions by communicating via CAN with the internal TCM (Transmission Control Module). The supplied Holley EFI OBDII Transmission Tuning Handheld is used to adjust Shift Points, Tire Size and Gear Ratio. The Terminator X V3 Software provides the ability to dial in Torque Management to optimize the desired shifting characteristics when using a 6L80/90E Transmission. Terminator X V3 software also allows a user to control the Secondary Shift Mode within the Transmission TCM and allows use of Tap Up/Down Shifting.

TERMINATOR X MAX MPFI 6L80 TRANS CONTROL |
| Description_ASC |
Not recommended for 4x4 applications with electronic transfer cases. Not compatible with 4L6X transmissions from model year 1995 or before due to year-by-year changes in converter lockup and downshift strategy. ECU is not recommended for marine applications, but can be used on off-road applications as long as you choose a safe location, keep it dry, protect from heat, and ensure proper wiring management. |

Four loose wires: |
| Description_FAB |
o Power (Red) – Supplies power to the transmission solenoids. This should be connected directly to the battery, or a constant battery source capable of supplying 5 amps |
| Description_FAB |
o Ground (Black) – Connect to a good chassis/engine ground source |
| Description_FAB |
o Brake Switch (Light Blue/White) – Wired to the brake light switch. This must be installed to a +12v source (as most brake light switches are) |
| Description_FAB |
o Park/Neutral Safety (Yellow) – Circuit for starter solenoid. When the transmission is in Park or Neutral this Yellow Wire will be Grounded (-). When the transmission is in gear this circuit will be open. |
