Rapid performance analysis and fault diagnosis is an essential part of motorsport. Life Racing ECUs include both time and event-triggered internal datalogging that can monitor hundreds of channels at up to 1000Hz including input voltages, calibrated sensor readings, intermediate results and control outputs. The advanced burst logging feature and large integrated memory allows more efficient data throughput and increased running times. The Sync Log is an additional, always-on logging feature that retains crank and cam sensor signal waveforms and angle-based event markers, for quick evaluation of any engine starting problems. The sync scope also automatically captures the high-speed waveforms when problems occur during running, making it a very powerful diagnostic tool.
