Hi guys,
I've only just joined the forums and i could do with some help. I've got a 120bhp Vectra CDTi. I've just bought a CR tuning box from ebay but it came with no instructions and i don't have a clue where to fit it. I really really need someone to post a picture of where it should go. Please could someone do this quickly as its really frustrating me. Thanks for the help guys,
Rich

Not a fun job to put a box in the 8v, you have to reach right round the back of the engine. Took me 10 minutes to put one in an 8v the first time, though it was alot faster the second time.

Biggest problem I had was releasing the yellow locking tab on the plug, used a long screw driver in the end.

Make sure the engine is cool first, don't want a nasty burn!

Finally managed to fit it. I had to use a long screwdriver to release the yellow clip too. Got it on, and i can definitely feel the difference. I am going to just turn it up a bit and see what happens. I don't know how many turns it was on to start with but it seems to turn quite a few times without stopping. any advice on this or should i just keep turning it a bit and trying it?

keep going, one turn at a time (stop the engine and take out the key before turning up the box) until it either starts to run rough at idel or you get smoke when you rev it.
