BSFC Scale

Colors of the power bar and the BSFC chart are based on a scale of efficiency.
Here is the reference for a 1.800cc Toyota engine.


Measuring charge efficiency

Hybrid Assistant can be used to measure charging efficiency on plug-in cars.
Here's a Ioniq PHEV charging at a wallbox: 3.3 kW out measured at the outlet and 3 kW entering the battery, with a 10% powerloss.


Current Gear Indicator for Niro and Ioniq

The new version of Hybrid Assistant, available on the Play Store, displays the current selected gear on Ioniq and Niro, even while driving in D.
Newer models of Kia and Hyundai car that previously displayed a wrong fuel consumption, now have a consistent indication.


High Precision Logging

While Hybrid Assistant main purpose is helping while driving, its data capture feature can be proficiently used by an expert technician for troubleshooting and fine tuning of engine parameters.
One example is LGP fuel quality evaluation, based on LTFT and STFT.
For this purpose, it's best to enable the High Precision Logging in the settings screen.
This will cause collection of data at the highest possible frequency.

Warning: enabling high precision logging will have a performance hit of about 2.5x.
Use it only when required.

This settings also affect the export data function of Hybrid Reporter.
Trips recorded with High Precision turned on, will produce logs with multiple samples per second.

As always, using a good and fast OBD adapter is highly advised.

Please note that, while performing an HV Battery Check, high precision logging will be enforced automatically.


Niro and Ioniq

Hybrid Assistant has now EXPERIMENTAL support for Hyundai Ioniq and Kia Niro.
Only a subset of the Hybrid Assistant features are available for these cars.

Braking using HyBall

During a brake, HyBall position can be controlled with the brake pedal pressure.
If the ball is green, you're using regenerative braking, while yellow and red will signal if friction braking is in use.
The amount of recovered energy is tracked by the ball position: if the ball is in the center, maximum recovery is being achieved.
For best braking, keep the ball in the center.


Interactive Maps

The new version of Hybrid Reporter allows live browsing of map data.
You can see where and how you performed in EV, Glide, Braking and fuel consumption, with real time zoom and pan.
