Both same year the cars?
Stock tune?
Pre restyling stock tune are garbage, they apply a different LTFT into open loop every time so you can end up richer or leaner than your average just depending on some stupid learning that the ecu does even before going into open loop
Restyling stock tunes are better at this
Do you mean pre-facelift? Yes, all cars in the class are 2013-16 BRZ or FR-S. The cars are not permitted to have a tune. Both cars are 2013s.

This is interesting about applying different LTFT at different times in open loop.

Are you saying that depending on what the car has learned during closed loop, the fuel is adjusted during full throttle/open loop?

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

Thank you for this information.
