Why not just run a 1.6M ECU and relevant harness and get a chip programed to suit, legal in Desmo Due but not in Minitwins. then you could run a 748/916 Revcounter and not have to wory as much.
Flemse has just had it done to his 999 and I know it has also been done on a 998 which also runs the 5.9M ECU but without the immobiliser
