Most of the standalone ECUs cater for data logging at an additional cost.
These range from simple engine logging to systems capable of instrumenting an entire vehicle including engine, transmission and chassis. All systems are backed by powerful Windows 98/XP based data analysis software.
Data logging allows for readings taken from Analog, Digital, Serial, CAN or Calculated channels, to be stored for later analysis on a computer. Most data logging systems use permanent non-volatile Flash memory. Data memory may be unloaded at very high speeds (approx. 19 seconds per Mbyte). Different logging options allow 384k, 1MB or the full 8MB to be accessed.
The best data loggers can can store channels at up to 1000 times per second per channel, this can be individually set for each channel. Four logging modes may run concurrently (Normal, Fastest Lap and two Burst Modes) each with selectable start and stop logging parameters. Memory can operate in stack or circular buffer mode.
