Last time I was looking into more power for the 1000 Watt amp, I considered putting this "ultracapacitor" next to the amp:
If you want to handle more electrical load you need to increase the output amps not volts. Increase the volts too much and you will destroy most of the 12V components, including the instrumentation.
What happens if you turn on the parking lights?so i actually did some datalogging of the ECU voltage:

This is from a cold start. The voltage is about 13.15V with the ignition "ON". but a fully charge LFP battery should be 13.5-13.6V. I'm unsure if this is since i'm reading from the ECU or if battery output voltage is limited by the BMS.
irregardless, the ecu never sees 14V
