Logging fuel trim (long term and short term) WRX107

[TRVIING]

Hi,

Could anyone shed a light how to log fuel trim for my 06 wrx? I tried a few few trim parameters but they were either 0 or shoot straight up to 100% (% fuel cut).

Please see the log file in google drive

That link requires requesting of access so I can't open it, "CL Lambda Fuel Corr." is the runtime value for teh Closed Loop lambda fuel correction setup which I assume is what you are after, "CL Lambda Status 1" will show what the CL Lambda is doing (and so explain why it is locked out etc).

Which fuel trim specifically are you wanting to look at? Also a copy of your tune could be helpful if the value you want isn't doing what you expect it to.

Sorry, Here is the link of the log again and the tuned map

I did try the CL Lambda Fuel Corr but no data shown.

Closed loop lambda is turned on in your map but it doesnt appear to have ever been set up or tuned so it is basically not doing anything.  Most of the time it is locked out due to TPS or MAP delta, the few times that the lockout conditions are met it still doesnt do anything because the minimum trim is set to 0% (ie ecu isn't allowed to remove 0% fuel). 

The fuel tune appears to be so far off that CLL is never going to work well, even if set up more realistically.  Your lambda is just about pegged on full rich the whole time the throttle is open.

Thanks Adam. That explains why I smell fuel all the time.
