TC-4 Plus Thermocouple Amplifier for MTS

The TC-4 Plus Thermocouple Amplifier for MTS is a precision data acquisition interface designed for serious automotive enthusiasts and professional tuners who demand real-time engine temperature monitoring during dyno testing and road validation. This four-channel amplifier bridges high-resolution thermocouple sensors to Innovate Motorsports data logging platforms—specifically the LM-1 and LM-2 systems—enabling simultaneous measurement of exhaust gas temperature (EGT), coolant temperature, and other critical thermal parameters across multiple engine zones.

The TC-4 Plus converts analog thermocouple signals into digital data compatible with MTS data acquisition networks, employing cold-junction compensation and low-noise signal conditioning to ensure accuracy within ±2% across the typical engine operating window. Its compact form factor (7.5 × 2.9 × 11 inches, weighing 0.85 lbs) integrates seamlessly into mobile tuning rigs and dynamometer control systems, while shielded inputs reject electromagnetic interference common in high-ignition-energy environments. Four independent channels allow simultaneous logging from EGT probes in different cylinder banks, turbocharger inlet/outlet, or intercooler circuits—critical for detecting lean conditions, boost stability, and thermal stress before component failure.

Tuners, engine builders, and motorsports teams rely on this amplifier to validate turbo calibration, confirm proper fuel mixture across load ranges, and track intercooler efficiency during development cycles. Installation requires connection to a compatible Innovate LM-1 or LM-2 data logger via the proprietary MTS interface; thermocouple harnesses and sensor probes are typically ordered separately. Whether you're optimizing a street-legal turbo build, preparing for road racing, or conducting OEM-level validation testing, the TC-4 Plus provides the thermal instrumentation backbone needed for confident, data-driven engine management decisions.
