yup, silver 1
easy to remove, unclip cowl (clips all round it so check they are all done if it wont give up easy) and take it and the rubber off, undo the 13mm's and take the rest of the cowl out, leaving the fan wiring attatched cos its 'got a screw'd into the shell' earth and a plug, easier to just lay it sumwhere
then unscrew the ecu
mind you dont trap the vacume hose or wiring when you refit the cowl tho as it will let water in and also pi55 your ecu and loom off a treat
also i have had chipped ecu's thet dont look any different inside
quickest way to tell is the DO NOT REMOVE warrenty sticker on the screw on the rear of the ecu, if its mint its never been apart (well shudnt have been neways

)
