Before an ECU design is finalized, the pinout and hardware undergo rigorous testing:
Analog sensor inputs (ADC)
The project began as a sketch on a grease-stained napkin. Elias knew that off-the-shelf units couldn't handle the hybrid-hydrogen turbine he’d shoehorned into an old '69 Charger. He needed a brain that could process thousands of data points per second. The was a masterpiece of multi-layered PCB architecture, featuring high-speed processors and noise-isolated signal paths to prevent the massive electromagnetic interference from the turbine’s ignition system.

“What did you do?” he asked.
