OptiMate VacuumMate Allweather TS-71 4-Channel Electronic Carburetor and Fuel Injection Throttle Valve Synchronizer Diagnostic Kit

The OptiMate VacuumMate Allweather TS-71 is the industry-standard, professional-grade diagnostic tool designed for fast and highly accurate synchronization of up to four carburetors or fuel injection throttle valves. Recommended by major motorcycle and marine OEMs (including Mercury, Honda, and Yamaha), this electronic device replaces unstable traditional mercury sticks with four medical/industrial-grade pressure transducers. Its rugged, water-resistant design and ultra-bright LED displays make it the ultimate tool for synchronization, engine speed tracking, and advanced valve troubleshooting in workshops, outdoor service areas, or marine docks.

Features and Benefits

• Precision multi-cylinder synchronization — Accurately compares and displays individual manifold pressures for up to four separate carburetors or fuel-injected throttle bodies on both 2-stroke and 4-stroke engines (expandable to 6 cylinders with an optional adapter).

• Solid-state electronic sensors — Utilizes four industrial/medical-grade Motorola pressure transducers that automatically self-calibrate for atmospheric pressure variations and resist damage from mechanical drops or engine vibrations.

• Advanced DYNamic troubleshooting mode — Features a specialized "DYN" mode that captures and displays vacuum waveform heights, allowing technicians to diagnose sealing differences, leaking intake valves, or piston sealing issues without tearing down the engine.

• Built-in wireless tachometer — Automatically tracks and displays active engine speed (500–2500 RPM range) entirely via pressure pulses from the intake manifold, removing the need for extra pick-up wires or alligator clips.

• High-visibility LED bar-graph displays — Equipped with four vertical bars comprising 40 high-brightness LEDs each, meticulously engineered to remain perfectly readable even under direct sunlight during outdoor or on-board marine testing.

• Allweather rugged composite housing — Enclosed in a shock-resistant, water-resistant molded polyurethane and polycarbonate casing with rubber-sealed switches designed to survive harsh workshop environments and even float if dropped in water.

• Rechargeable cordless operation — Powered by an internal 7.2V NiMH battery providing up to 6 hours of cordless autonomy, which can be easily recharged using the included 12V DC vehicle battery lead.

• Fixed OE-recommended resolution — Delivers a precise, fixed resolution accuracy of 0.5cmHg, meeting the strict calibration standards recommended by premium powersport and marine manufacturers.
