Holley Sniper Automatic Transmission Controllers

The Holley Sniper Transmission Controller (STC) is designed for common GM and Ford electronic 4-speed automatic transmissions. Three part numbers cover a complete range of applications—all Sniper EFI systems, Sniper 2 EFI-specific (M8 CAN connection), or a full standalone unit. The Sniper specific applications connect to your Sniper EFI system via CAN bus and are programmed through the existing Sniper 3.5 in. touch screen. No programming is available with PC computer software; however, the transmission functions can be data-logged and reviewed with Sniper PC software. The Standalone version includes a dedicated 3.5 in. touch screen and is primarily intended for carbureted engine combinations. GM and Ford 4-speed electronic overdrive transmissions are simple in operation. They have four speeds, with the top gear being an overdrive; and all have a lockup torque converter that eliminates any slippage when the lockup is applied. With a stock torque converter, the lockup should only be applied under light throttle conditions or excessive wear will occur. Upshifts, downshifts, and torque converter lockup are based on vehicle speed and throttle position (or optionally the MAP sensor) and are adjustable with the 3.5 in. touch screen. P/N 551-100: Replacement controller unit only P/N 551-101: Controller unit and power harness only P/N 551-102: Standalone kit for carbureted applications (includes power harness and hand-held programmer) P/N 551-103: Controller unit and power harness for use with Sniper 2 EFI systems Holley Sniper Transmission Controller features: * Adds electronic transmission control functionality to a Sniper 2 * Controls conventional electronic 4-speed transmission applications.

Holley Boost Control Solenoids

Holley boost control solenoids are designed for optimal performance when using the boost control function of Holley EFI. Some setups require two solenoids and some require one. They're driven by a Pulse Width Modulated (PWM) output of the ECU. It is advised NOT to use the PWM+ outputs on a Holley HP ECU, but rather use the PWM- outputs. If you have a Holley Dominator ECU, use either the PWM- outputs or a PWM+ output on the J2B connector.
