I am using the Torque(android) software for dataloging, the long term fuel are always 0 at wot, is this normal or i must watch it at part throttle, also can i read the injector duty cycle with this software?
thanks.

I think it's normal to see 0 at wot since it goes into open loop. I'm interested in reading IDCs as well if someone knows how to. Are you running it with a bluetooth adapter and own bad is the lag you are experiencing?

yes with bluetooth, the data are approximatly 0.8-1 sec interval,
if at wot we see o open loop, how others say they have 10 or 20% - or +, they measure the ecu capability of adding or leaning with part throttle or idle?

Your fuel trims will only be active in closed loop. In open loop they lock in at whatever value they were at when you exited closed loop. Getting your fuel trims to lock in at 0 or as close as possible is a very good and indicates that your fuel curve is spot on.
