Overview The Haltech TCA 8 4+4 delivers eight channels of programmable thermocouple amplification in a single compact unit, pre-configured to appear as separate TCA-4 Box A and TCA-4 Box B modules in your ECU Manager software. Perfect for serious motorsport builds requiring comprehensive EGT monitoring across multiple cylinders, turbocharger systems, or complex temperature mapping throughout your engine bay and exhaust system. Technical Specifications Part Number: HT-059908 Channels: 8 thermocouple inputs (4+4 configuration) Display Configuration: TCA-4 Box A + TCA-4 Box B in ECU Manager Connection: Direct CAN bus integration Compatibility: Elite ECU CAN port, Elite Harness CAN connector, Elite 4 Port CAN HUB Installation: Plug and play with Elite ECU systems Why You Need This When you're running a serious build — whether it's a twin-turbo LS swap, high-boost 2JZ, or multi-cylinder RB engine — monitoring exhaust gas temperatures across all cylinders becomes critical for both performance tuning and engine protection. Individual cylinder EGT monitoring reveals lean cylinders before they cause damage, helps optimise fuel maps under load, and provides essential data for turbocharger temperature management. The TCA 8 4+4 eliminates the complexity and cost of running two separate TCA-4 units while providing the same eight-channel capability. This unit excels in applications like V8 engine swaps where you need comprehensive per-bank monitoring, turbo builds requiring pre and post-turbo temperature measurement, or race applications where detailed thermal analysis drives setup decisions. The dual-box software presentation means your existing ECU Manager layouts and logging templates work seamlessly — you're simply adding more channels without software complications. ECU & System Compatibility Direct plug-and-play compatibility with the complete Haltech Elite range including Elite 550, 750, 1000, 1500, 2000, and 2500 ECUs. Integrates seamlessly with existing CAN networks via Elite ECU CAN ports, harness CAN connectors, or expanded CAN setups using the Elite 4 Port CAN HUB.
