Long Time Fuel Trim and Short Time Fuel Trim

[nelsant]

Hi!

Fiat Marea 1.6 16V 100hp, year 2000.
ECU Magneti Marelli IAW 49F.
ELM327 bluetooth from Electronic Fuchs.

Is it possible to check Long Time Fuel Trim and Short Time Fuel Trim?

I bought full licence to see more info, including LTFT and STFT... But I see exactly the same info as on free version.
The only diference, now it's possible to use reset ecu function.

Is this correct/normal? Or should I see more info?

Thanks.

That is normal!
Basicly when you buy full version on some models you get extra adjustments tab.
All parameters should be more or less the same (in free or full version).

Thanks alfa156sarajevo!

Does any one know if it's possible to check long and short fuel trims on Magneti Marelli IAW 49F?
Another software? Another device?
It has a 3 pin connector, not OBD.

Yani... Do you consider an update on Multiecuscan to check LTFT and STFT?
If possible on this ECU...
