Cruze 2013 Stock file questions...

[smithers]

Some questions first on the stock calibration:

Engine >> Torque Management >> Engine >> Map A - Normal. (all tables in here)
The X axis vehicle speed is in km/h but the labels appear to be rpm, thoughts? (e.g. 400,800,1200,1600 etc...) - Answer...Driver demand tables will calculate the vehicle speed axis using RPM and NV ratio calibration when VSS is enabled.

Engine >> Torque Management >> General >> OverBoost Limit is Zeroed out?

Engine >> Fuel >> General >> Stoich AFR. Why is 0.00 Alcohol Composition 14.12988? This should be closer to 14.681 should it not? Is there a reason why the factory has this setting?



Are there any good logging configs for initial tuning?

Unless you have the diesel or Euro-spec, the overboost doesn't exist.

GM changed the stoich to be a little more realistic as to the actual gasoline put in people's vehicles. Non-oxygenated gasoline is quite rare.

Hmm,

Strange, MTBE or any additive is rare to non-existent around here.. Most of the 91 octane stations around Alberta are non-oxygenated gasoline, no ethanol either. Most of Canada for that matter. I use 14.681 AFR for all my tunes...Surprised to see this for a Canadian vehicle... but probably dont give Country specific tunes.
