Carburetor / Fuel injection throttle valve Synchronizer, RPM & valve diagnostics, battery powered

The VacuumMate Allweather is a professional-grade, all-weather synchronizing tool designed for precise and efficient balancing of up to four carburetors or fuel injection throttle valves on both 2-stroke and 4-stroke engines. Trusted by marine, motorcycle, and powersport technicians, it is the industry standard for fast, accurate manifold pressure measurement and adjustment—ideal for workshop, onboard, or outdoor use.

This advanced synchronizer features four individual high-brightness LED bar displays (40 LEDs per channel), clearly visible even in direct sunlight. It measures manifold pressure with a fixed resolution accuracy of 0.5 cmHg, using four industrial-grade Motorola pressure transducers for exceptional reliability. A built-in tachometer reads engine RPM from pressure pulses—no extra pickup needed. The DYNamic mode further enhances diagnostic capability by identifying valve sealing differences between cylinders.

With three selectable sync pressure ranges and engine speed readings between 500 and 2500 RPM, VacuumMate ensures optimal tuning performance for a wide variety of engines. The device operates on a rechargeable 7.2V NiMH battery with up to 6 hours of autonomy, or it can draw power directly from a 12V vehicle battery.
