In the process of resurrecting a rallye, but unsure on a few things,
I was told the engine in it is running cams and remapped ECU but this engines bottom end is away.
So I bought a spare standard engine and was planning to put it in, but don't think the ECU will run it,
So I got a soft unlocked ECU,

And the questions:-

- is as simple as put the engine in and plug ECU in and it works?

- will the chip in the key work with the chip in the ECU ?

- will this mean the immobiliser won't work ?

- is it possible to reset a mapped ECU to save any hassle ?

That's about all the questions I have at the min, any help greatly appreciated

If you use the unlocked ECU you must disconnect the immobilizer as if you didn´t do it it will lock again

In that case it may just be easier to keep the camed head and just replace the bock,
