Where do I find the ECU's to find out which one I've got?
Open up the bonnet, and on the right hand side (as you look into the engine bay), behind the battery is a triangular shaped plastic fuse box. Open this up and the ECU is on its side in there (silver), pull it upwards and it slides out so that you can see the serial number (X XXX XXX XXX)
If you want to check if it is socketed or not, then you will have to unplug it, bend back the metal tabs and open it up full (T8 & T20 Torx reqd.)
Hope that helps 
Meanwhile, back at the plot . . . . . . . . . . . .
I have got the ECU out of the car and the first thing I noticed was the number ending in 427 on the back, being the optimist I am I presume this is the number peeps have been talking about....?

I have then bent the metal tabs back (and sliced my hand open in the process) and having removed all the Torx heads I have removed the boards and carefully opened them up as described. The first thing I notice is that the 2 centre chips in the run of 4 across the top of the board are different from the pic Platty posted earlier but from reading posts an I right in thinking that it's the chip on the left of the 2 below these that I am interested in . . . . . . ?

Also, previous posts mention a 10 digit code on this chip. If this chip is the right one, the code printed on it takes the format XX XXX XX XXXX XXXXX.X If this is the wrong chip then it won't matter, but if it is this one, how come I've got a much longer code?
It's all good fun aint it
