Innovate MTX-A Series 52mm (2-1/16") Analog Boost / Vacuum Gauge Kit | 20 PSI | Black Dial | High-Torque 270° Stepper Motor | Programmable Warning | Innovate MTS Serial In/Out

The Innovate MTX-A Series 52mm Analog Boost/Vacuum Gauge Kit (INN3857) is a microprocessor-driven analog boost and vacuum gauge in Innovate Motorsports' MTX-A series — a 2-1/16" (52mm) gauge featuring a high-torque 270° stepper motor for superior needle holding force in high-shock and high-vibration applications, programmable warning indicators, and Innovate's MTS (Modular Tuning System) serial in/out for integration with other Innovate and third-party MTS-enabled devices. The black dial kit includes interchangeable black and silver bezels for flexible installation aesthetics. The MTX-A series is Innovate's premium analog gauge lineup — microprocessor-driven precision with the clean, traditional analog needle display that many performance enthusiasts prefer over digital readouts. Innovate Motorsports is one of the most respected performance instrumentation brands in the North American market — known for their wideband O2 controllers, data logging systems, and MTX-A gauge lineup.

Key Features:

• Microprocessor-driven — the MTX-A series uses a microprocessor to drive the gauge needle — superior accuracy and needle stability compared to traditional analog gauge movements
• High-torque 270° stepper motor — high-performance, high-torque stepper motor with a 270° sweep — superior needle holding force for high-shock and high-vibration applications — the needle holds its position accurately even under aggressive driving conditions
• 20 PSI range — reads from vacuum (negative pressure) through 20 PSI of boost — correct for a wide range of turbocharged and supercharged performance applications running up to 20 PSI of boost
• 52mm (2-1/16") diameter — standard 52mm gauge diameter — correct for 52mm gauge pods, pillar pods, and gauge clusters
• Programmable warning indicators — programmable warning indicators alert the driver when boost or vacuum reaches a user-defined threshold — a configurable safety feature for monitoring boost levels
• Innovate MTS serial in/out — Innovate's Modular Tuning System (MTS) serial in/out allows the MTX-A boost gauge to be daisy-chained with other Innovate MTS devices (wideband controllers, other MTX-A gauges) and third-party MTS-enabled devices — adding additional logging channels to a single data logging system
• Black dial — black dial face with clear markings — a clean, performance-oriented gauge face design
• Interchangeable bezels — includes both black and silver interchangeable bezels — choose the bezel finish that suits your interior aesthetic
• Innovate Motorsports quality — manufactured by Innovate Motorsports, one of the most respected performance instrumentation brands in the North American market

MTX-A Series — Microprocessor-Driven Analog:

The Innovate MTX-A series bridges the gap between traditional mechanical analog gauges and fully digital displays — using a microprocessor and stepper motor to drive a traditional analog needle with the accuracy and programmability of a digital system. The stepper motor's 270° sweep provides a wide, easy-to-read needle arc, while the high-torque motor design ensures the needle holds its position accurately under the vibration and shock loads of performance driving. The MTS serial connectivity allows the MTX-A boost gauge to be integrated into a broader Innovate data logging system — a significant advantage for builds where multiple parameters are being monitored and logged simultaneously.

Innovate MTS — System Integration:

Innovate's Modular Tuning System (MTS) is a serial communication protocol that allows Innovate devices to be daisy-chained together — connecting multiple gauges, wideband controllers, and sensors into a single data logging system. The MTX-A boost gauge's MTS serial in/out allows it to be integrated with:

• Innovate wideband O2 controllers (LC-2, LM-2, etc.) for simultaneous boost and AFR monitoring and logging
• Other Innovate MTX-A gauges (oil pressure, water temp, EGT, etc.) for a complete multi-gauge MTS system
• Third-party MTS-enabled devices for additional logging channels

The MTS integration makes the MTX-A boost gauge the correct choice for builds where data logging and multi-parameter monitoring are part of the instrumentation plan.
