Unlocked ECUs

[Grant]

If should, but I'd personally just remove the wiring from the pins on the ECU plug / round engine bay plug.

I think (and I'm going by memory here as I don't have any of my wiring notes here at work) that all the immobiliser related wires go through the smaller of the two round engine bay plugs, although as said that's from memory and it's possible that I'm thinking of Xsara VTS looms. Certainly all the wires that you need to make the engine run, the dash gauges/lights to work and the DL16 diagnostics connector are on the larger round plug as I've kept this when I did the wiring on my 205 GTi-6.

If you want to be completely sure then pay someone to completely remove the immobiliser, but certainly I'm confident enough in soft unlocked ECU's to run them on my own 205 and other friends and cars that I've converted run the same way without issue.

Other option if it's a 306 is just to buy an ECU with the matching key and immobiliser/BSI gubbins of course and have it running as Peugeot intended.

Thanks for the info. Problem is, I have an ECU and BSI in front of me. So if I can trouble someone to plug it into their car and let me soft unlock it, it saves me a fair few quid. Problem in, the BSI is PH3, im PH2.

the bit in the rear quarter is just the cl relay IIRC, you'd only need to remove the transponder box from the bottom of the dash.

I was thinking that. The bastard thing is unplugged anyway. Useless thing
