Connected Car vs Cyberattacks

"Connected cars are quickly rising and becoming part of everybody’s life. According to a MarketsandMarkets forecast, this industry will reach $46.69 Billion by 2020. So far so good, but, this evolution comes hand in hand with cyber threats expansion, so, there is only one thing we can do – make sure security comes first."https://www.rickscloud.com/connected-car-vs-cyberattacks/

Be sure to use an OBD adapter that do not accept unsolicited pairing requests.

Brake Specific Fuel Consumption

"Brake specific fuel consumption (BSFC) is a measure of the fuel efficiency of any prime mover that burns fuel and produces rotational, or shaft, power. It is typically used for comparing the efficiency of internal combustion engines with a shaft output.
...
Commonly BSFC is expressed in units of grams per kilowatt-hour (g/(kW·h))."- Wikipedia

Hybrid Assistant shows BSFC in the Engine Power Meter using a color scale reflecting efficiency:
Red - Best efficiency range (220 g/kWh)
Orange - High efficiency range (230 g/kWh)
Yellow - Medium efficiency range (240 g/kWh)
Cyan - Low efficiency range (> 240 g/kWh)

Actual thresholds vary with engine type, according to official Toyota documents

Understanding Hybrid Assistant "bubble" charts

Hybrid Assistant uses "bubbles" to represent data on scatter charts.
Size and color are proportional to accuracy of the data point represented.
Check the following chart, that depicts relationship between RPM of the petrol engine and kW produced.

For each RPM value, all kW measured at that regime are averaged and plotted.
A blue, large dot is made up from few collected values, so it's precision is low and the plotted point may be affected by statistical errors.
An orange, medium dot is plotted when more data is available and precision is higher.
A small red dot means that a sufficent samples were collected to have a reliable value.
Longer trips lead to more defined charts.

Quality of OBD adapters

While the Hybrid Assistant team tries to support as many OBD adapters as possible, some of them are just plain garbage.
Most of them are based on the ELM327 chip, or better, an older version of it.
The first version of the ELM327 was released without any copy prevention measures.
This leaded to a number of unauthorized low-cost clones.
While the official ELM327 grew from version to version, security mechanisms were introduced to discourage copies.
So, right now, there are several clones claiming to be the latest version, while they are simply renamed clones of the old one.
While the chip identifies itself as a newer version, its command set is still the older one, so some command are not behaving as expected.


Another whole group of clones even cut shorts on components: low quality interfaces and controllers, and even missing components.




Buying this products supports piracy and divert resources from companies investing in developing new products.
