usb splitter

Logruss, Can you or anyone else confirm that the splitter is working, and you are logging WB? I have tried 3 already from Frys, and have a real old ticket in the support system that I keep responding to, but doesn't look like that's working.
(GN4ZYBU4DQ)
I want to make sure, if I can, which USB splitter is working for the LC1 from someone already successfully using it. So far 3 for 3 with different errors.

Thanks
M

well i just copied my whole 2.6 folder, renamed it to 2.7 and then downloaded the updated beta and put the new files in that folder.

Hamish, any how-to or guide or something that I'm missing on how to do Map Tracing for the Evo X? I'd really really appreciate some help, I'm supposed to get tuned this weekend on a dyno and map tracing would make it 10000000 times easier.

Thanks!

Mine had a random BSOD also last night- running Windows XP SP3 with EvoScan 2.7 Beta 4.

I restarted the computer and opened it up and it ran fine after that, not sure why it did that.

yeah I had mine sitting in the passenger seat at idle yesterday, nothing being changed and the laptop/cables not being moved...BSOD again. previously I suspected that I might be kicking a cable out or something disrupting the communication since it only happens when it's logging.

Update: EvoScan v2.7 Beta5
- New Feature: Added "Set DataLog Folder..." option under the Logging menu.
- New Feature: EvoX SST Gearbox Temp Reading added to 2008 JDM EvoX, someone can test it on the other EvoX's see if it is accurate.

You can download and extract the files in this zip file into your exisiting evoscan v2.6 installation folder. (c:\Program files\Evoscan\EvoScan v2.6\)

EvoScanv2.7beta5.zip

I have two data.xml files that have different values on my pc, can anyone confirm the correct formulas for these ones:

Mode23 2008 JDM EVOX:
InVVT Eval="(x-4096)*-0.01953" or Eval="(x-3552)/48.64+10"
Load (MIVEC) and (Timing if IATS GT 75F) RequestID="2380876c" or RequestID="23808774"
Load (Timing if IATS LE 75F) RequestID="23808F68" or RequestID="23808F70"

Mode23 USA EVOX:
InVVT Eval="(x-4096)*-0.01953" or Eval="(x-3552)/48.64+10"

NEW: SST Temp in DegC
<DataListItem DataLog="N" Color="" Display="SST Transmission Temp" LogReference="SST_TM_Temp" RequestID="CAN28-0" Eval="x-50" Unit="Deg F" MetricEval="x-50" MetricUnit="Deg C" ResponseBytes="1" GaugeMin="0" GaugeMax="1000" ChartMin="0" ChartMax="1000" ScalingFactor="1" Notes="" Priority="1" Visible="False" />

yeah it appears I uploaded the wrong data.xml, and it also appears that it doesn't log, even after I tested it on the same EvoX early in the week, and I haven't made any changes, lol. I'll release a new beta version for th sst temp and for the ecu reset feature.
