Comment on Hacking an Audi: performing a man-in-the-middle attack on FlexRayComments−_pmf_6yOn the Q8, the FlexRay bus has cycle time of 5 ms, so each ECU can send messages at 200 Hz.That's weirdly worded. The cycle repeats (disregarding multiplexed PDUs) every 5 ms, but there are lots of messages within a cycle.Even on CAN, it's not uncommon to have > 2000 msg/s (looking at Daimler trucks with 70% utilization).
