Can anyone tell me where I can find this on the car. Took car back few months ago as not running as it should (racing hot idle, stuttering when pulling away hot). On the work sheet I saw "? replace ECU". When car returned they told me they had found something obstructing the throttle cable which they had rectified. Car was certainly better but am just curious as to whether in fact they took the opportunity to upgrade the ECU. Am told you can tell by the colour of sticker it has on it?

Regards, Nick.
