ALFA ROMEO FIAT KKL Interface MultiECU Scan Alfadiag
[LEZBITAL4091]

works great with fiat ecuscan. You have to change wiring for systems other than engine but that goes without saying plus easy enough to do (see fiatecuscan site) It has a good clean circuit board, excellent price and received next day.

As a side note I bought this because my local Fiat Dealer do not have any idea how to do anything yet have relieved me of hundreds of pounds for basically nothing. Reading reviews of fiat dealers on the internet proves I'm not alone.
