Right... but all closed loop systems are slave to a set of known physical engine environment parameters that they trim the motor's behavior around.
For example, fuel trims aimed at keeping a target AFR that reflects a stoichiometric mixture of gasoline and air will not do a good job of adapting to a new fuel with different stoichiometrics, such as methanol, without changing the parameters. It will just run poorly as it tries desperately to tune for the wrong fuel.
As soon as you change the physical parameters without updating the ECU, it's anybody's guess.
We definitely need more info from JUN.
