So: For Spitz Data Log and Turnigy dlux data logging ESC's, the programming is identical, and the downloading of data is identical.
Are there any other similarities ...? Well the specs of similar rated models are quite similar:</p>

<span style="font-size: small">Turnigy dlux 70A SBEC ESC w/Data Logging:</span> http://www.hobbyking.com/hobbyking/s...a_Logging.html
Weight: 84grams
Max Cont. Current: 70A; Max Burst Current: 85A
Max BEC Current: 3A; BEC Voltage: 5.5v; LiPo: 2~6S</p>

<span style="font-size: small">BMI Spitz 76A Data Log ESC:
</span>http://www.bmi-models.com/index.php?...ATA-LOG/6/4409
Weight 85g
Current A 76A; Peak A 85A
BEC 4A ; LiPo 2~6 LiPo</p>

-The weights are almost identical, so are current ratings. There is a slight difference in quoted BEC current.</p>


<span style="font-size: small">Turnigy dlux 100A SBEC ESC w/Data Logging:</span> http://www.hobbyking.com/hobbyking/s...a_Logging.html
Weight: 96grams
Max Cont. Current: 100A; Max Burst Current: 120A
Max BEC Current: 3A; BEC Voltage: 5.5v; LiPo: 2~6S</p>

<span style="font-size: small">BMI Spitz 106A Data Log ESC:
</span>http://www.bmi-models.com/#en/85611_...ATA_LOG/6/4410
Weight 106g
Current A 106A; Peak A 115A
BEC -None; Opto -yes; LiPo 2~6 LiPo</p>

-The weights are in the same range; current ratings are similar; Of course, the BMI 100A ESC has no S-BEC ...
In general, however, this comparisonis at least consisent that Turnigy dlux and BMI Data Log ESC'sare made in the same factory ...</p>
