MTS SSI-4 Plus Sensor Interface 4-Channel

The MTS SSI-4 Plus Sensor Interface 4-Channel from Innovate Motorsports is a precision data acquisition module designed for serious engine builders, tuners, and performance enthusiasts who demand real-time sensor monitoring and logging capabilities. Whether you're developing a custom ECU tune, validating engine performance on a dyno, or troubleshooting complex fuel and ignition issues, this interface bridges aftermarket sensors to your laptop or tuning platform. It's built for the professional who refuses guesswork when optimizing air-fuel ratios, boost levels, and combustion timing.

The SSI-4 Plus accepts four independent analog sensor inputs simultaneously, allowing you to monitor multiple parameters—lambda output, fuel pressure, manifold absolute pressure, exhaust gas temperature, or any 0–5V analog signal—through a single, compact interface module. Its rugged construction and shielded cabling minimize electrical noise interference that can corrupt tuning data at the millisecond level. The 4-channel architecture is optimized for real-world engine bay environments, with industrial-grade connectors that endure vibration and thermal cycling without signal degradation, ensuring your data stream remains clean and repeatable across multiple test pulls.

This module excels in standalone ECU tuning, motordyne turbo development, and dyno validation workflows where simultaneous multi-channel acquisition is non-negotiable. Professional tuners integrate the SSI-4 Plus into MoTeC, Haltech, and open-source tuning platforms, while weekend warriors use it to correlate wideband lambda readings with boost pressure during street tuning. Installation requires basic automotive wiring knowledge and a USB connection to your tuning computer; compatibility spans virtually any modern forced-induction or naturally aspirated engine platform requiring sensor-level diagnostics and performance logging.
