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 SDU ICB was co-developed with Cascadia Motion, an industry leader in EV propulsion systems, to ensure the highest standards of quality and reliability.
