2. Variation in driving behavior can make a 35 40 difference in fuel consumption 5 Why does the Fill up log report GPM instead of MPG A MPG is not a linear scale A good way to illustrate this is with a question If you wanted to help the environment which would be better trading in a 30 MPG vehicle for one that is 45 MPG or exchanging a 12 MPG vehicle for one that gets 19 MPG If we turn the terms over it is still not a linear scale but it is easier to relate to day to day life A good example of this is to turn on the Mileage by 100 option press i on the fill up summary screen to find it This simply shifts the decimal place on the results but suddenly you can see I need x gallons to go 100 miles or it will cost me x dollars to drive 100 miles Rather your goals are saving money or reducing your carbon footprint we believe that GPM which is similar to the European standard of liters per 100 kilometers is generally more useful 8 Software Developers Kit SDK Information about the MTS data stream has always been available on request In addition Innovate Motorsports has long provided some basic SDK tools to make accessing measurement data from our hardware easier for third party applications What is different about the OT 2 SDK is that in addition to documenting how to access the MTS data stream it also provides information on how to dynamically configure the OT 2 basically access and alter the feature

22. o not hesitate to log partial fill ups The fill up summary averages over all contiguous entries so your long term data will still be correct Similarly it is not necessary to top up the tank to the absolute fullest for accuracy Again the tool averages over time Topping up tends to be bad for the environment There are many tips on saving money on gas But based on the data we collected in testing there are three that we can recommend First slow down Simply obeying posted speed limits saved our testers an average of 11 in fuel Second cruise control If you have it and can use it it appears to improve economy an average of about 9 Third fill up early in the morning on Wednesdays Yes that last one is odd but it is two factors combined Statistically fuel prices appear to be lowest on Wednesdays and early morning is generally when the fuel is dispensed at its lowest temperature 3 3 LogWorks Tab There are three pages in the LogWorks The first gauge display can be configured to display any three channels and allows the start and stop of a log The second page displays all the channels selected Before using the LogWorks tab it is necessary to configure which channels are in the OT 2 tab which is reviewed in the next section 3 3 1 Channel Selection in the OT 2 tab 1 Press the OT 2 tab 2 On the upper left hand corner you will see a icon which is used to enter a configuration screen alternatively p
