quick trim vs quick tune ( link G4 )

Dear Andre ,

What is the main difference between quick tune and quick trim ? bcs i see both do the same function

when we do use one instead of the other ?

and if we use the quick trim after get a ramp run on dyno can the ecu link capture the cells data accurately so we can tune cells after the run ?

The quick tune feature requires you to hold the engine in the cell long enough for the adjustment to be made. Quick trim can be used based on logged data to correct the AFR errors you saw during a dyno pull or a log file from the track. This is helpful on engines that you don't want to hold at high loads for extended periods while the quick tune function does its job.
