A new low cost data logger - and how to use it on cars

Last week in Five Gutter USB Data Logger, Part 1 we introduced the new eLabtronics USB data logger – a unsophisticated and cheap (AUD$86.90) logger than can work with up to five 0-5V inputs. It’s consummate for monitoring engine management sensors.

This week, we look at some car uses.

To use the logger on a car engine management system, you trouble access to the signals. This access can be gained at the ECU, but you’ll for to know on exactly which pin each signal is available. And, as described above, the voltage will want to fall within the 0-5V range. Most workshop manuals will show you the pins on which sensor signal voltages will be found, and better workshop manuals will show you the chain of values that you can expect to see in normal car operation.
