Just been doing some work on the car, and I found that the Unichip and boost sensor module were not secured and were loose in the bottom of the passenger cubby hole s:shock: :shock: s:shock: s:evil: :evil: s:evil: s:evil: :evil: s:evil: s:roll: :roll: s:roll: I'll be having a long 'chat' to Millway about that.
I secured them with gaffer tape, but noticed one of the wires and pins had come free from the Unichip plug and was dangling loose s:( :( s:(
I taped the modules down, and insulated the end of the wire .... but now the car doesn't start at all.
So - does anyone have a 2003 ECU pinout diagram, a Unichip installation digram (I need to see where the connected pins in the plug go) and in particular, info on a wire in the ECU loom - a black wire with a red stripe ?
I'm really hoping I can work out where the 'spare' wire goes back into the Unichip plug, and get the car running again, especially before the Elvington Trackday next Saturday.
Sent you an email (address as in www) containing EWD (2.5MB zip). Hope it helps.
Roger - BIG thanks for that. (http://www.imoc.co.uk/forums/images/smiles/icon_thumright.gif)
Have found that the wire that has been pulled out is a switched +12v feed from a Black/Red wire in the ECU loom - so basically there's no power getting to the Unichip - this would explain why the engine isn't running.
(Hmm, I thought the Unichip would have failed 'safe' but obviously not)
Edit : just found a Unichip wiring diagram on a site, and have replaced the the 12V wire back into the correct hole in the Unichip connector .... after some major spluttering and coughing the Roadster is running again s:D :D s:D
I'm just off out to drive some twisties to 'check' its all OK
