Install a Tesla Model S or Model X Base Large Drive Unit (LDU) in any vehicle and achieve complete control with AEM EV's LDU Inverter Control Board (ICB, PN 30-8402) and an AEM Vehicle Control Unit! This system provides full control of the LDU for programming torque curves, torque limits, regenerative braking, accelerator pedal response, drive-mode switches, and much more. The Tesla LDU currently comes in two versions, Base and Sport. AEM EV's Tesla Inverter Control Board acts as a VCU expansion device that replaces the stock Tesla ICB. Once connected to an AEM VCU using the supplied communications harness, calibrators can program propulsion strategies and characterize inputs through the VCU using AEMcal software. AEM EV's LDU ICB was co-developed with Cascadia Motion, an industry leader in EV propulsion systems, to ensure the highest standards of quality and reliability. NOTE: The Inverter Control Board must be used with an AEM Vehicle Control Unit for programming and controlling a Tesla LDU. This system is designed for conversion and motorsports vehicles with Tesla LDU swaps. It will not control a Tesla LDU in a Tesla OE chassis
