The \u003cstrong\u003eHaltech Ti8HP\u003c\/strong\u003e removes that step. It connects a Gen 1 8HP45, 8HP70 or 8HP90 to a drive-by-wire Haltech Nexus ECU, and the gearbox is flashed through the Haltech system itself, with no third-party software or reflash tools needed.\u003c\/p\u003e\n\n\u003ch3\u003eWhat it does, and what it doesn't\u003c\/h3\u003e\n\u003cp\u003eThe Ti8HP is a transmission interface, not a transmission controller. The 8HP's own control unit keeps handling the shift logic, while the Ti8HP passes the signals it needs, such as engine torque, between your Nexus ECU and the gearbox. It reads the gearbox's original binary and flashes the Haltech binary through the Haltech system. Out of the box it runs and drives as per factory.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePlugs into the transmission connector on Nexus Rebel LS, Rebel JZ and Rebel K terminated harnesses, or wires into any other drive-by-wire Nexus ECU or VCU\u003c\/li\u003e\n\u003cli\u003eNo third-party software or reflash tools\u003c\/li\u003e\n\u003cli\u003eAdjustable prefilled torque table, which sets line pressure and clamping force\u003c\/li\u003e\n\u003cli\u003eShift load correction for small shift point adjustments\u003c\/li\u003e\n\u003cli\u003eUpshift torque reduction for sharper upshifts\u003c\/li\u003e\n\u003cli\u003eDownshift throttle opening to smooth the rev-matching blip\u003c\/li\u003e\n\u003cli\u003eTransmission fault codes shown on the ECU\u003c\/li\u003e\n\u003cli\u003eSeparate box on its own CAN bus, so your ECU keeps a spare CAN port for ABS, a BCM or a factory dash\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eHaltech has also announced trans brake, clutch control and custom shift points as planned additions.
