Cruise control issues after box change

Hi,
I have recently had my gearbox changed on my R52 (2005) I had checked both cars on RealOEM to check they where both the same gearbox which they where (New box from 2006 R52).
Since the replacement cruise control only seems to work in 3rd gear and won’t trigger in any other gear, the light does not flash or anything just does not engage.
Would anyone know how to fix this issue? I have seen this issue appear in other threads but no one ever seems to add the fix.

The doner car did not have cruise control no idea if that’s an factor

Cheers
Callum

You have different gear ratio now.Only way to solve the issue, is to write new gear ratio in Engine Control unit.

I didnt think the gear ratios would change with them both been Getrag gearboxes. Would you know how to code new ratios? I do have ISPA (Or whatever its called) so i have a semi understanding in coding the minis
