This one's easy:

• The graphical nature of Data Log Lab makes the examination of data log contents so much easier: trends and fluctuations are instantly visible rather than hidden in tables of numbers.  

• Any events during a car's performance are captured permanently for in-depth analysis afterwards at leisure.

• You don't have to rely on your memory of an event, or try and reproduce it whilst watching the displays and dials when you should be watching the road!

• You quickly generate your own library of reference data that enables back-to-back comparisons.

• You can perform analysis across an entire data log rather than just at a single point in time.

• Data Log Lab's Power Graphs are a significant aid to all after-market ECU owners:

- Allow consistent and effective tuning of your car without the need for expensive rolling-road time.

- Give a quantitive and definitive answer to the question "Has my latest performance modification made any difference?".

- Give early warning of failures and problems by allowing the regular monitoring of engine power output.

- Allow instant comparison between cars when the owners live miles apart and don't have access to the same rolling-road.
