   Hi guys and gal
   Ive just bought a mk1 saxo vtr. Its a circuit racer and it cam with a few bits .... Problem is i havent got an ecu. Which is were im getting stuck.
   Can i bolt any old mk1 vtr ecu on to the car or will i need to key. ie is the key coded to the engine ecu or is it coded via a seperate ecu module and therefore can i use the original key and any ecu i get from a scrapper.

   look at the ecu connector
   
   are all the pins the same size? if so you need an unlocked bosch mp5.2
   
   if they have narrow ones in the middle you need an unlocked bosch mp7.2

   Its a single plug connector for the ecu.. I got given a mk2 3 plug ecu which is unlocked and superchipped but i dont have the wiring loom to fit it.

   Ive just had a look at my wiring loom. All the pins are the same size. But if i got the 7.2 and wiring loom off ebay would that still work on my engine???
