TT ECU will not control the NA Fuel Controller. Use a NA ECU with a TT PROM. and run Different boost controllers, and aux fan control.. IF you are keeping the same Trans Type. Best to contact a Z Supplier and tell them what your doing.. they will recommend.. and supply proper stuff. USUALLY the ECU Chassis needs to stay with the Car Chassis, and ECU PROM needs to be the Motor and Trans Type .. but exceptions apply
