Does anyone use a DAQ checklist to guide them in what they check/look for (in what order) to get the most out of a limited period of time. Any help would be appreciated. I'm working on mine but standing on the shoulders of others would really help.

Thanks, Jay

A General DAQ Analysis Strategy

1. Check data for overall health of the engine. Check rpm, pressures, temperatures and voltages. The Longitudinal Gs can also be evaluated for overall engine health. Use the min/max statistical view to confirm engine is working properly in order to catch anything requiring immediate attention.

2. Always compare the current session’s fastest lap with historic (last session, last month, etc.) fastest lap(s) at the same track. Is the driver/car faster or slower? Find out why considering:
a. Similar ambient conditions.
b. Tire conditions and temperatures.
c. Any changes made to the track/car.

3. Overlay several laps (whole session or at least the serious laps from the session) and look for inconsistencies and find out why considering:
a. Traffic.
b. Driver behavior.
c. Problems.

4. Use best rolling lap vs. theoretical best and compare with fastest(s) laps. Use time slip function and look for descending lines (these are areas where gains can be made). However, ignore quick/rapid descending lines in the braking areas.

5. Check Lateral G peaks turn by turn for consistent handling behavior. Find out why they differ. Use of the X/Y plot (Traction Circle) can help.
a. Installation error
b. Banking or road surface
c. Car not capable of generating more Gs
d. Driver or car problem

6. If the car setup has changed use Long G/Throttle Histogram to evaluate.

7. Speed is king. Always overlay speed and find out why it changed.
