An amazing set of tools

Ive been driving on track for the last 5 years. The tools provided by Harrys Lap timer are very helpful. Ive gained real insight into where on track I am loosing time and what I need to do to address.

Im using the suite of tools. Timer on my 3GS iPhone, an external GPS as well as the OBD II interface to collect the data. Im then using the iPad for review and analysis.

The next step up in data acquisition and analysis in my book would require an additional investment of >1K to get more meaningful data.

Great product Harry!
