when i had a new fob programed to the SCU recently the guy told me that its as easy to switch ECU's between SCU's as it is to reprogram a new fob to an SCU. you just need to tell it. and the guy would only charge you a tenner. so you could use with existing SCU, no problem aslong as you know what your doing. But as Stamford says the standard ECU is self learning +/-10% i believe so, is it worth it for only 5 BHP gain?
