The Scan Gauge web site lists all of the x-guages under various headings. One of the headings is "Enhanced Data" and then just below: " Ford PWM". I've tried to get the torque ( CTQ ) and fuel level ( FL ) loaded as x-guages but without success. Anyone out there have advice as to how to gain access to this data?

The FEH is CAN, so don't use the VPW or PWM codes. CTQ is not supported by the FEH. For the FEH, engine torque is PID 09CB. However, this is, I think, a scaled 2's complement value so an exact xgauge I haven't yet figured out how to do. The fuel level appears to have incorrect MTH entries, so try the following:
There is a built-in xgauge for torque that is calculated using the horsepower and RPM, but LL didn't put it in the manual due to issues with overflow and strange values displaying under certain conditions.
I met Gary Gattis today and explained to him that I was looking to use the SG II to generate a power required versus speed curve for my new MMH. The ICE shaft horsepower is readily available, and I was looking for a way to get the traction battery contribution. Traction battery speed is available, so I was looking for traction battery torque. Then its (Q x RPM)/5252 and I'm home.
Thank you all. Not knowing what any of the acronyms stood for, I guessed that the CAN represented vehicles shipped to Canada, thus the alternative, PWM, must apply to US vehicles.
For more info on auto communication protocol, Google on OBD-II, or OBD2, etc. Several methods are used. CAN is common on newer vehicles, and all our FEH/MMH use that protocol. Pulse Width Modulation (PWM) is used extensively on most other older Ford Products. Variable Pulsewidth Modulation (VPM) is a common GM product communication protocol.
Unfortunately, not all of the guages published by Linear Logic are functional.
For instance, the first two under Ford CAN, CTQ and BAR are disfunctional.
( yes, I realize that one can revert to MAP on the basic list to obtain local barometric pressure with the ICE OFF )
John, The 2008 models, at least the AWD versions like mine, all seem not to be capable of reading the Traction Battery Temperature (BTM). Even some of the 05-07 model years have this problem. I haven't tried all the entries Linear Logic has posted. The one work around for battery temp that does work for me is Tav, which other folks say is pretty accurate after the vehicle has been on for a period of time. All in all, I'm pleased with the SGII-Xg
