VBOX HD2 Help

VBOX HD2 Help
I have owned my HD2 for several years, purchased it from @ProCoach back when he was the US Rep. The system is great and this winter I decided I would add CAN data to my setup. This i where the "Help" comes into play.
My car is a 2000 996 GT3 Mk1. I believe that I should be using the 996 Ref files for the CAN data. I have searched and followed what I believe is the correct installation directions. I also downloaded a copy of @ProCoach's detailed instructions (996 GT3 CAN PDF).
What I have done:
1. Found the Blue/Gray twisted pair wires near the fuse box (driver's side foot well).
2. Attached the Blue/White wires from my VBOX HD2 unterminated cable to the Blue/Gray wires. See picture.
3. Attached the Red wire to fuse E1 in my fuse box and the Black (ground) wire to the car ground (phillips screw with a brown ground wire attached)
4. Updated all of my software and firmware to the latest and greatest.
5. Updated the scene I have been using for years to include the CAN data in the settings.
6. Updated my scene components: Engine Speed for RPM and Throttle Position for a bar graph. See Pictures.
7. Loaded the new scene onto the VBOX HD2
I figured that would be it but when I start the car I do not get RPM nor Throttle position. I have tried to log all CAN signals (via the settings checkbox) but that doesn't seem to do anything.
So I am wondering if anyone might have some ideas or suggestions to help me. Much appreciated, thank you.

You can DM me but you should UNCHECK "Send Acknowledge" and "Log all CAN bus messages to file." That can throw a curve ball getting the right information. I have had issues with '98-'01 996 cars but got good information from a 2000 996 Turbo just a few months ago coaching for a couple days with the same connection as you used.

Update on where things stand. I reached out to Racelogic Support and we have been emailing back and forth; my support rep Kyle has been super helpful and responsive. I have also continued to dig for more information the 996 and its ECU.
I finally found a couple of threads that shed some light on things. The following is the one that helped tremendously:
https://rennlist.com/forums/data-acq...and-motec.html
To get to my ECU I had to pull out my passenger seat since (as we know) the ECU is back behind it mounted under a metal plate.
I only pulled the plug off my ECU, which is a Bosch 5.2.2, and then checked the wires in the bundle. There were only 2 twisted pairs in the bundle, both basically the same wire colors: BL/TAN and WH/BK. No BL GR pair, but at this point that was what I was expecting since @Slakker said in the @kgorman post that there were no wires in the 996, you have to create them.
So I opened up the plug and added a twisted pair (CAT5 cable) and connected that to my Racelogic cable. Now I have CAN data b ut the 996 REF file does not seem to be working. I'll emaiul my results to Kyle on Monday.

That's so strange. I don't recognize ANY of those twisted pairs. How do you know you have CAN data if the template doesn't work?
Must be a 2001 and earlier issue, because I have connected successfully with no fewer than two dozen 996 S, Turbo and GT3 models. As a matter of fact, the 996 template was from raw data I harvested in 2012 from a 996 GT3. But again, it was a 996.2 car, not a .1, which should be the same as 986.1.
All I can think of is the Spec Boxster ('96-'99) dilemma, there are engine speed and throttle position that come through at 50 Hz, CAN IDs 316 and 320, and one RL wheel speed at 10 Hz. Other channels like engine load and and torques for the tranny controller are not particularly useful.
Kyle is a great resource. Good luck.
Ticking the Harvest Raw CAN Data and sending the ,asc log along with the .vbo and the scene should help them suss it.

I may move the car a bit and turn the wheel as well as hit the brake and gas pedal to capture as much information as possible for Kyle.

This shows the 2 twisted pairs I may have identified. Pins 18 and 19 have BK/WT and WT/BK wires that join up with BL/RE wires in a twisted pair. The 2 BL/RE wires are joined together at pin 46.
Again, there were no wires at pins 85 and 86 which is where I put the CAT5 wires to allow me to tap the CAN BUS.

I never actually got my ME5.2.2 CANbus working with my VBOX Lite but it worked fine with my AIM MXS dash. Make sure the 120ohm terminating resistor is turned on in the HD2. You might end up having to add physical 120ohm resistors, which is way and cheaper than it sounds, but I'll see if I can do a little testing this week and create a .dbc reference file to try.
