Unless it's for an ultra rare model then testing is lilley to cost more than the ecu is worth, just my opinion based on what people have told me
in the past that they had paid.
What engine is it for ?
Unless I am in a rush or it's a seller's market I usually wouldn't pay much more than £25, I did pay more for one from a focus Rs
but there where only around 2250 sold in the uk.
I agree selling on Ebay is getting hard work with people expecting new items for old money and argos style service. But just stick it on as untested.
I’ve been asked if I would do one of these. I normally decline as there just to labour intensive but as I’ve never done a granny cosi I said I may
have a look.
Just done a first start on the St220 3.0, I love these standard ecu’s. You plug them in and turn the key and go.
If Bob is an eecv then yes it would be pats and would need the matching rfid chip. But on the plus side they gain obd2. I think the bob is harder due
to the gearbox control rather than pats.

Thanks Warren & Jim, they will be a great help, it seems the plug on my EEC is wired for a different version, some key connections missing, e.g
left and right o2 sensors, and some pins wired which shouldn’t be...
