Unlocked ECUs

[Grant]

If you connect a soft unlocked ECU to a car that has the immobiliser wiring, BSI etc still in place and connected to the ECU then it will re-lock.

If you connect a soft unlocked ECU to a car without any of that then you'll be very unlucky if it ever re-locks in my opinion - apparently it's not unheard of, but 95% of 205/309 GTi-6 (along with S16, 2.0 Turbo etc) conversions will be done that way and I don't ever recall hearing about a single one re-locking itself over on the 205 forum.

So, IMO, a soft unplugged ECU on a 306 where the wiring for the immobiliser has been disconnected should be fine.

So if I were to remove all the black boxes of crap (its a PH2 with half under the dash and half in the rear quarter) then all should be fine?
