|Both systems do the following (assuming the use of the optional GPS module with the MQ200):
- GPS track maps
- GPS lap and segment times
- GPS-based Lateral and Longitudinal acceleration
- GPS-based MPH
The GPS-based measurements are all sampled at 5 Hz (5 times per second) for both the MQGPS and the MQ200.
The difference is that the MQ200 allows you to add additional sensor inputs, like MAP, Throttle Position, RPM, etc. Also, the MQ200 has an internal 3-axis accelerometer, so you can get high-fidelity lateral/longitudinal/vertical acceleration data. The sampling rate for acceleration and other sensors is significantly higher than GPS, giving you more detailed information. You can add OBD-II as an option to the MQ200.
The MQGPS is a good choice when you are racing your daily driver and you don't want a complicated installation. It is popular for autcrossing, lapping days, or drag strip test & tune. It gives you the most important data quickly without having to connect anything to the vehicle wiring harness.
The MQ200 is a good choice when you have a car prepared for the track and you are able to tap into existing sensor wiring or add sensors. You get more detail in your data, and you can monitor more things on the car. Road racing, circle track racing, off-road rally, and professional motorsports are the typical applications for the MQ200.
We also have a number of customers using the MQ200 for engineering R&D.
