Hi All

I have been having a poke around with my 2.7L 2000 model Boxter ECU today using my Galletto. It can detect the ECU ok but it comes up with a garbled Italian translated message when I try to read it that says 'Put Pin 24 Flash EPROM to MASS' etc. I have read another post on the forum explaining how to do this on a bench but I was wondering if any one has done with the ECU still in the vehicle. I dont have a bench rig so powering it isnt going to be easy and my soldering skills arent that good so I'm a bit twitchy about doing it on the bench.

I'm sort of figuring that shorting the correct pin to ground through a resistor then turning on the ignition will have the right effect but it would help of someone could verify this.

Any help would be greatly appreciated.

thanks

Ian

Oh and before any wise a**es post 'take it to a shop' I dont want to I want to do it myself for the journey wherever that may take me (hopefully that will save you the effort of typing unhelpful comments)
