FTC definition

[liviner]

I've used google and forum searches looking for a definition of the available fuel trim cells values (PID 6310). Maybe I'm not using the right search terms, but it would be nice to have a list of the cell values and the conditions each represent since 6310 is such a useful PID for filters.

Corollary: would these values/definitions be different on the gen V (specifically E92) platform from earlier ECMs?

This is from the old Help docs. The .EU website still exists and works but the US (.com) website was replaced by the newer version. No idea why they left out so much from the old help...
So, while it still works I'd recommend you save any pages you want to keep...

Not sure if it's 100% applicable to Gen5, but if you are seeing similar numbers or a similar pattern of numbers, you should be able to figure out some basics like decel, idle(a/c on and off), etc... after reading over that page.

Thanks for that, but I'm fairly certain based on my research it changed to only 0-15 cells for gen IV and later. So far, I found the below on this old post related to gen IV.

cell 0-5 Airflow based, Purge On
cell 6 Idle, Purge On
cell 7 Decel, Purge On
cell 8-13 Airflow based, Purge Off
cell 14 Idle, Purge Off
cell 15 Decel, Purge Off

This line up with what I've logged, as decel always corresponds to cell 15, and low throttle steady state driving is typically 0 or 8.

Also, if I base my filtering on the above 0-15 definitions, it cleans the logs up nicely for my needs.

Looks like FTC (PID $1190) in Gen 5 is exactly the same as in Gen 4.
I've compared E38 OS 12639835 and E92 OS 12659566.
