There's a very active discussion on the FEH/MMH (Ford Escape Hybrid/Mercury Mariner Hybrid) forum about the recently updated ScanGaugeII. This firmware update adds the ability for the user to add additional displays, and the "XGauge" capability allows the updated ScanGaugeII to display vehicle-specific information, like NiMH battery State of Charge, voltage, and current, and motor-generator speeds, etc. ( See http://www.scangauge.com/support/xgauge.shtml.) The rub is that one needs to know the vehicle-specific codes that will allow one to access this information! There is such code information available for the Prius and FEH/MMH, but I have seen no such information for the TCH on the Web. Does anyone here have such information, or know where it can be found? Our vehicle seems to be missing out on this opportunity, and I for one would be very interested in having this ability. I haven't had my two ScanGaugeII's updated yet partly because of this very lack of information.

I'm copying below a relevant posting of mine from the FEH/MMH forum concerning the appropriate parameter setting for TPS (Throttle Position Setting) that would be needed on the updated ScanGaugeII in order to properly register fuel-cut operation, and so correctly compute both fuel usage and FE.

"I find it very interesting to read how Ron DeLong eventually dealt with the fuel-cut issue in ScanGaugeII. I had a lot of e-mail communications with him on this issue back in April. This is what I find in my Toyota Camry Hybrid (TCH):

• Before the first start of the ICE, the TPS reads 18 (open-loop of course).
• When the ICE first starts up in really cold weather (well below freezing), it initially stays open-loop for some seconds. During this brief period, the TPS appears to read between 15 and 17. On going closed-loop, while still at idle, it rises to 19 and then drops slowly to 16 as it warms up.
• When fully warmed up, and idling, it reads 15-16 (closed-loop).
• When fully warmed up, and in pure-EV mode, it reads 15 (open-loop).
• When coasting in pure-EV mode, it reads 14-15 (open-loop).
• When coasting in fuel-cut mode in 'D', it reads 15 (open-loop).
• When coasting in fuel-cut mode at high speed in 'B', I have seen it read 19 briefly, before dropping to 15 (open-loop).

I shall monitor the cold-startup TPS and open-/closed-loop behavior of my TCH a bit more over the next little while, and report back if I need to modify the statements I made in bullet #2 above.

So, for my vehicle, a setting of 16 or 17 would seem to be appropriate. My TCH always reads open-loop when it goes into fuel-cut."
