That does not sound like a bad idea theoretically, but I suppose the mapping adjustments could be poorly done.
Thank you for this information.

yes, that 's how LTFT applied in open loop works
it should learn the correction around 2.8-3v of maf voltage which is more or less the threshold between closed and open loop and then the ecu applies it into the open loop section
I dont know exactly how this work and actually not really interested anyway as i disable LTFT in open loop anyway in all the tunes I do
in stock tune there is a +-40% margin of LTFT that can be applied
In openflash tunes is tamed to 2%
in custom tunes is basically turned off by every tuner
an aftermarket filter panel like k&n for example usually already leans things out , but how LTFT reacts to that can be at times really random, that's why stock tune is garbage for this
