Hi what is the best diagnostic tool that fits and works on alfa gtv 2.016v Tspark 916 series 16 pin
If you have a laptop, log in to www.Multiecuscan.net and buy the software for 50 euros. All you only then need is to purchase the cables from Ebay. :)
I have calibrated my selespeed actuator and diagnosed faulty sensors on varies Alfa's with this and it works.
