RPM/Trim/Timing Chart

Following an interesting post on PriusChat, https://priuschat.com/threads/e85-3-gal-e10-7-gal.121314/#post-1730070
a new chart has been added to Hybrid Reporter: you can see efficiency at various RPMs, based on Ignition Timing and Fuel Trims.
Ignition Timing points can also be painted with the BSFC value achieved.
This can be useful when using different fuel types (LGP or E85).

High Precision Fuel Chart

The High Precision Fuel Chart has undergone a major restyling.

The new High Precision Fuel Chart combines fuel efficiency with burning efficiency, giving an unprecedented insight view of engine workings.

As always, the left vertical bar depicts L/100km instant value, but it's color is drawn using the BSFC color scale.
You can now see how efficiently you are burning the fuel needed to achieve a specific mileage.
The best desirable condition is a short cyan bar.

LGP fuel quality evaluation

Joshue Martín de Blas, a long time friend of Hybrid Assistant, has put to good use the Fuel Trim charts of Hybrid Reporter.
In his own words:

These 2 Fuel trims graphics are of the same trip, but with different LPG brand. It's clear that in one case the effective Fuel Trim is bigger (and the fuel consumption higher also), because the ECU needs to make much more corrections tho the injection time.

Fuel usage over distance

The Fuel usage over distance chart plots consumption on a distance scale.
The green line shows overall fuel usage starting from the beginning of the trip, while the red histogram depicts local fuel consumptionin every single kilometer of the trip

Instant Fuel Consumption

The Instant Fuel Consumption chart shows fuel consumption in L/100km along with speed

BSFC Trend

See how BSFC is getting better over time, with steady speed and high engine temperature:

Fuel Chart

The Fuel Chart shows real time instant and average fuel consumption.
Values are shown in L/100km

The Fuel Chart is available in 2 versions:
  • Standard
  • High Precision
Standard chart has a refresh rate of 1 second and a longer timeframe is displayed on screen

High Precision chart has the highest refresh rate permitted by your OBD adapter: it can be as fast as 5 times a second, but an high performance adapter and phone are mandatory for proficient use.
High Precision chart also uses colors to highlight ascending and descending trends in fuel usage.

You can open the Fuel Chart by tapping the EV icon.
Tapping anywhere into the chart will close it, and performing a long tap will switch between Standard and High Precision.


A) Instant consumption: the bar size changes to display fuel usage in L/100km. Bar color changes according to usage trend: green if instant consumption is less than the previous reading, orange if not.

B) History area: this area keep history of fuel usage. A vertical mark is drawn every minute, with a thicker one every 5

C) A green area shows decreasing fuel usage

D) An orange area shows increasing fuel usage

E) Average fuel usage over the whole trip is also plotted: red when increasing, green when decreasing
