You will need to use the CarSoft software to tell the ECU that its now a manual transmission insteal of a manual. The computer believes the car is still an Auto, and this will cause problems.

Bingo. Also need to make sure you have a functional clutch cut out switch so the car can't be started accidentally with the clutch engaged.
