The MQGPS is a breakthrough in capability, price, and ease of use compared to older accelerometer-based systems.  No worries about leveling the unit, no errors due to roads that aren't perfectly flat.  Stick it to under your windshield and go test.  Easily transfer the system to another car for comparison.  Use a Pocket PC or Laptop PC for flight recording, real-time display, and analysis.  Or, with the new MQGPS-TraQr, record directly to internal memory, no Pocket PC required, then download your data to a laptop for analysis.

All MQGPS systems provide the same data capture and analysis capabilities.  Here are the differences:

•  MQGPS-5 Hz: use with a Windows Mobile Pocket PC or Smartphone, up to 5 Hz sampling, in-car lap timer and data readout, record time limited only by Pocket PC memory (your entire racing season in your pocket!)
•  MQGPS-TraQr: cheapest and simplest overall solution, one switch operation, runs standalone without a Pocket PC (therefore no in-car lap timer or data readout), 6 hours of record time, 5 Hz sampling

How to Choose:

• I am a competitive autocrosser who needs to see data immediately after each run.  I don't have much time for analysis.
  Solution: MQGPS-Quantum or MQGPS-5Hz with Pocket PC
   
• I am a road racer who wants data acquisition and a dashboard lap timer.  I drive a production-based race car.
  Solution: MQGPS-Quantum or MQGPS-5Hz with Pocket PC
   
• I drive a kart or Formula car, I'm doing detailed vehicle engineering development work, or I just want the highest fidelity data without regard to cost.
  Solution: MQGPS-Quantum with Pocket PC
   
• I am a road racer/HPDE driver/drag racer/autocrosser who wants the simplest, cheapest solution.  I don't need a dashboard display, and I'll use my own laptop to look at the data after I do my runs.
  Solution: MQGPS-TraQr

Just how accurate is it?  Validation testing consistently shows timings within a few hundredths of a second of dedicated track timing systems:

(MPH readings are slightly higher than trap speeds because they are calculated at the line, not as an average over the previous 66 feet)

The MQGPS also works with third-party mapping and navigation software that can handle update rates greater than 1 Hz.
