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.

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.


Engine Stats

The new release of Hybrid Reporter adds a statistics page.

You can see actual engine usage in hours over a selected period of time.

Running time is an important parameter in evaluating engine wear: for example, oil lifetime can be estimate by hours rather than kilometers.
Statistics are provided based on data collected by Hybrid Assistant: consistent results are possible only if Hybrid Assistant is used on every trip of the car.

The development team of Hybrid Assistant strongly advise to strictly follow Toyota guidelines for periodic maintenance.
Data provided by the Hybrid Reporter statistics page can be used for informational purposes only.
