Key differences btw DL-1 and DL-90:

- DL-1's GPS receiver is integrated into main logger unit (vs. separate, smaller box w/ DL-90)
- Faster GPS sampling rate on DL-1 (5 Hz vs. 1 Hz)
- Greater data capacity (uses Compact Flash storage for up to ~100 hrs of data depending on card size, vs. ~90 min for DL-90)
- Many more analog and digital inputs, including lap beacon input
- RS-232 port can be used as another logger input (e.g. for OBD2 data)

Actual data accuracy (limited by GPS and accelerometer accuracy) is unchanged, although the faster sampling rate may make the DL-1 more precise.

 

Version 5 of the analysis software is now available with video integration... amazing stuff. No longer free, though. http://www.race-technology.com/WebPage2/Pr...re/NewInV5.html

 

Cheapskate autocrossers like myself usually use Geez, although I'm personally quite interested in acquiring a GTech Pro RR.

I hadn't heard of the GEEZ before. What do the others give you that it doesn't? Does GEEZ generate all speed and distance (and position) data from the accelerometers? How accurately can it do that?

 

I have started autocrossing and have looked at both the GEEZ and the D1. As the GEEZ is much cheaper I called and left a message but didn't get any call back. How does one buy a GEEZ?

 

It states on their site to call 1-800-909-0818.
