ecu with chip £200 - 250 used

loom £200 used

MAP sensor £80 brand new

so £500 is about right

personally, i would not buy a used loom. i would get a new one of dingy (le-claw) or ryan don't know their prices, but quality is spot on. old looms could be unreliable

do a search, there are plenty of posts with pictures of L8 ecu's and the correct numbers
