I have installed Magnaflow exhaust and after installation I had an issue installing the flap/ valve actuator connector and resolved by programming the Ecu to install the connector in installation position and recalibration.

The ecu is showing no errors but when starting the car, the exhaust flap valve will be open position all the time and couldn’t be controlled even by switching to normal / Sport mode.

Hey buddy,

Middle East and Australia Supras don't have the same exhaust flap option as in the US and Europe .. the flap is always open.

i have the same situation here in Asia. But all of the mkv's around me (same country) their normal/sports mode valve flap works when modes are switched.

Mine used to work but I installed my aftermarket exhaust and dp after having my car's ecu updated by Toyota due to their recall. Not sure if its because of that or something else.

Did anybody had the same experience and solutions to that? Thanks!
