just to let you know, I just fitted what is allegedly (sp?) an SS ecu. got it for about 400€. Car goes like stink now, normal mode is realy pleasant now as opposed to the slightly asthmatic feeling it had with the original 135 hp ecu. On sport mode it's the bomb
Installation was easy, had "check engine" message first time i turned the key to "mar" but ignition of and 4-5 pumps of the clutch and ingition on again it was gone. Car started and runs without problems.
There are several people selling them on the italian cinquecenisti forum.
I wonder how they get hold of them. Are the ecu's "re-virginised" from write off SS's? or are they getting them through the back door of abarth spa? Are the ecu's in fact reflashed standard ecu's with a copy of the SS mappings?
Plot thickens. lol
Anyway, so far I'm more than happy, I got an esseesse'd engine for a bargain, money saved for a Bilstein kit I guess, lol
