MSD Atomic Transmission Control Modules

MSD Atomic transmission control modules are designed to adjust the operating parameters of later model electronically controlled 4-speed automatic overdrive transmissions. They're simple to configure with the supplied hand-held monitor--no PC required. You now have access to adjust shift points, adjust torque converter clutch behavior, select different levels of shift firmness, select between auto-shift and manual shift mode, and activate dyno mode to deliver repeatable chassis dyno results. The included hand-held monitor connects to them and can be left in place as a dashboard to monitor the transmission in real time, or can be disconnected when the configuration is complete. Once installed, these modules need only a few basic parameters to complete the initial setup. First, select the type of transmission you are using--all supported transmission types are listed in the menu. Other required fields include the number of engine cylinders, rear-end gear ratio, and tire height. Once this has been completed, you can now start and drive the vehicle, while taking advantage of the advanced setup menu items to dial-in the transmission to your liking. You can feel the results in real-time as a passenger manipulates the parameters and monitors the real-time data. Data available for viewing includes engine speed, vehicle speed, throttle position, transmission fluid temperature, shifter position, and commanded gear. Best of all, the MSD Atomic transmission control modules are available as completely stand-alone units or Brainwave-compatible for the Atomic EFI systems. A transmission controller harness is sold separately.

Within Terminator X V3 PC Software: --- Virtual Torque Management Tables --- Virtual TPS Tables to dial in shift characteristics regardless of engine --- DBW and Timing torque reduction tables to create smooth shifts Within the Holley EFI OBDII Transmission Tuning Hand-held: --- Ability to read and clear TCM fault codes --- Ability to raise and lower shift points by MPH or RPM --- Support for Tap Up/Tap Down & Transmission's Secondary Shift Mode If you currently have a Terminator X ECU, upgrading to a Terminator X Max ECU can be easily done by plugging your main harness into the Max ECU and re uploading your existing calibration. Holley Terminator X MAX GM 6L80/90 transmission kit features: * Included TCM hand-held tuner with integrated wizard is required for setup in conjunction with the Terminator X 3.5 in. hand-held. Terminator X V3 software unlocks optional tuning parameters. * Plug-and-play with any engine controlled by a Terminator X Max ECU * Supports: Shift Mode - Tap Up / Tap Down, and torque management * Four loose wires: --- 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 --- Ground (Black): Connect to a good chassis/engine ground source --- Brake Switch (Light Blue/White): Wired to the brake light switch. This must be installed to a +12 V source (as most brake light switches are) --- 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.
