When And Why?:

When trying to diagnose driveability problems or assessing how well a new tune is working with the vehicle datalogging can be an invaluable tool.  By looking at what is going on with the vehicle under load or other conditions you're able to look at a picture in time and see if there were any issues or problems that would need to be addressed and sometimes where and why they occurred.  However a datalog is only as good as the monitors you record, much like how a map is only as useful as the information it has on it

How Should I Drive When I Datalog?:

Because most of the problems people have are those that show up under heavy load, we want to have some good boost characteristics over the datalog.  Therefore we recommend you find an empty stretch of road so that it's not only safe for other people, but safe for you.  When trying to diagnose a problem it's easy to have too much to look at, so when trying to diagnose something we recommend keeping it short and simple.  In these instances a datalog of a single run from 2500rpm to redline in 3rd gear (if running a 5-speed) or 4th gear (if you have a 6-speed) ensures you don't have to spend time sifting through extraneous data to find what you need.  If your problem has to do more with idle characteristics perform the 2500rpm run, but sometimes taking a look at what your car does at idle can be of some help.  Lastly if you're a road racer you may want to datalog for long streches of time which, when paired with track telemetry, can help you figure out when and where things were going well, and when things were going bad, this can help diagnose more intricate problems like fuel slosh or oil starvation.  However as datalogs get bigger sifting through the lenghty spreadsheets can get difficult and time consuming at that time you may want to invest in a datalog viewer program which converts your spreadsheets into simple graphs so you can go through a bunch of data all at once.
