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. GM 4L60/70/80E and Ford AODE and 4R70W - transmission specific harnesses sold separately: -- 558-405 – GM 4L60/70/80E -- 558-455 – 2009+ GM 4L60E -- 558-470 – 1998+ Ford 4R70W/4R75W -- 558-471 – 1992-1997 Ford AODE/4R70W * Tuning is performed through the 3.5 in. touch screen LCD (included with the Standalone version). Future compatibility will include 5 in. display and Bluetooth module * Tune upshifts, downshifts and WOT shift points * Full programmability of torque converter lockup * Full tuning of transmission line pressure (shift firmness) * Controls and layouts interface mirror Dominator and Terminator X MAX ECUs (except no paddle shift) * A MAP sensor is needed if using MAP for line pressure, which is usually only done with forced induction applications

Holley Sniper OE Style 255 LPH EFI Fuel Pump Modules

Holley Sniper offers OE-style 255 lph EFI fuel pump modules for a wide range of vehicles, including many Chevy, Pontiac, Buick, Oldsmobile, GMC, Ford, Mercury, Jeep, Dodge and Plymouth cars and trucks from the 1950s, '60s, '70s, and '80s. These in-tank modules are high-pressure units that flow 255 liters per hour (LPH) and are capable of supporting electronic fuel injection (EFI) engines producing up to 550 hp. A pre-calibrated fuel level sending unit designed to work with the factory fuel gauge for this application is included. Each module also features a HydraMat filter which has a unique internal reservoir that keeps fuel available at the pick-up and also provides protection from contaminates. Fuel pressure is internally regulated to 58 psi, eliminating the added expense and effort of purchasing and installing an external fuel pressure regulator; no separate return line is required because these modules return excess fuel right inside the tank! The Holley Sniper EFI fuel pump module was designed as a direct replacement for your factory pick-up and sending unit. There's no need to purchase a custom EFI fuel tank. You can even retain the factory fuel hard line—just connect the outlet of the pump module to the hard line on your vehicle with EFI-rated fuel hose and hose clamps available in the Earls Vapor Guard line.
