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.




some more information on fuel trims may be found here:

HV Battery Capacity Estimate

During an HV Check, an estimate of the battery capacity is also shown on screen.
All models (except Prius Plus and Prius Plugin) have a nominal 6.5 Ah battery capacity.
To evaluate capacity follow these guidelines:
1) be sure to have at least 60% SOC, engine and battery at operating temperatures (i.e. not too low or too high)
2) park the car
3) start A/C at the lowest temperature, to put some load on the battery
4) be sure the petrol engine is not running and have completed S1 phase
4) start HV Check
5) keep the check running until actual SOC is at least 10% less than the starting SOC

The Estimated Capacity will change color when enough data will be collected.

The same information is present on the report from Hybrid Reporter


New Release

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
