#2 of 7 Scanguage by dsgd47 Aug 25, 2006 (1:17 pm)
You can buy a Scanguage to monitor your performance. This box plugs into your OBDII port and gives you current/trip/tank info on mileage and also shows many other engine details. It can tell you immediately how your driving is affecting your mileage. You will need to calibrate your unit by buying a couple tanks of gas.

Replying to: dsgd47 (Aug 25, 2006 1:17 pm) My scanguage does not list CNG as one of the fuels option for calibration. Do you used LPG or gas? Replies to this message: londnr (Jan 24, 2007 3:45 pm) gonzalju (Jan 24, 2007 7:02 pm) londnr (Jan 25, 2007 9:29 am) and 1 more...

Replying to: gonzalju (Jan 24, 2007 12:54 pm) I asked the folks at scanguage if it would work with CNG - the answer I got from Ron DeLong was:   "The ScanGaugeII will work on CNG even though there is no selection for it. To make fuel use accurate, you will have to add a known amount of CNG at a fillup. This is not easy with CNG. You would have to fill it to a repeatable level, drive until it is low on fuel and then refill it to the same level again. You would also need to have a filling system that can accurately tell you how many gallons you have added. The accuracy to which you can do this will dictate the accuracy of the fuel economy and use shown by the ScanGaugeII."   Hope that helps.

Replying to: londnr (Jan 24, 2007 3:45 pm) When you performed the originaal set up for the type of fuel, did you input gas or LPG? Replies to this message: londnr (Jan 25, 2007 9:29 am) gonzalju (Jan 29, 2007 6:56 pm)

Replying to: gonzalju (Jan 24, 2007 7:02 pm) I haven't bought or used a scangauge, I am still considering it. I would be interested to hear of anyone's experience though.   As for what fuel type to select, I couldn't tell you, but the folks at Scangauge seem friendly enough and I am sure they will give you an answer.

Replying to: londnr (Jan 25, 2007 9:29 am) I own a scangauge which I use on my 2005 CNG Civic. So far I am very satisfied with this product. You can scan the car's computer for fault codes, retrieve a lot of very useful information from multiple screens and use it as a trip computer. I have been able to diagnose what is causing the check engine on my car to light on and what sensor needed replacement. The one thing is not reliable enough for a CNG vehicle is any calculation that requires precise energy content information or tank measurements. Regarding energy content I was told to use the LPG option as it is the closest to CNG. That did not work and I was getting huge variations on the MPG calculations. When I tried using gas it did work much better. My guess is that by compressing KGs of NG at 3600PSI in a 8 gallon tank Honda has been able to be very close to the energy content of a gallon of regular gas (GGE). Pass this you still need to get accurate and consistent fillings which in my experience is hard to do. Once I calibrated the unit with the best filled(low temperature,etc) the multiple calculations are accurate. The only exception is any calculation that is using information from the tank: gas left, miles left, etc. These calculations will vary depending on how complete was the filled. For that reason I would never rely solely on the scangauge to decide when to fill (CNG only). Besides that I am very happy with the unit.
