Thanks for the update! Now all makes sense because I was intrigued with odd problem which was not possible to describe/diagnose in full by all we tried before.
Just note that if MEMS3 ECU is remapped one then there is possibility that your MEMS3 has removed neccessitiy to have paired alarm ECU with MEMS3, meaning, you could start car without any pairing. If you start the car but it die within 2 seconds then you need to pair the alarm ECU with MEMS3.
As I know P1487 and P0655 are related. P1487 provides info about hot wngine from engine bay sensor and P0655 provides info that your hot engine lamp on the dash is not working.
However, these error codes might be thrown from completely different reason like inoperative lambda/oxyven sensor.
Do you have any troubles with engine when driving or similar?
NNN000160 is MEMS3 ECU for 1.8 VVC engine so if your car is TF160 then it is correct for the engine. However, I do not know if this ECU identifier is written in the ECU and if it can be altered if mapping is done. In that case you have correct map in the ECU, but ECU itself was not originally NNN000160 one.

As far as I know all throttle bodies for Rover 200/25/ZR have idle screw adjustment, either plastic or metal throttle bodies. Mems 2J is used in case of Vi and BRM so yes, they do have idle screw adjustment.
Just be aware that there are two versions of Pektron alarm softwares and boxes in regard to boot opening. One have that option, other do not.
So, even if pscan enables this option, you might not get it if you have other software in the box.
