hey guys
since I buy my punto mk1 and I am woundring to know how to diagnose it with an OBD2 scanner .. and I know that I do not have an OBD2 connector on my car .. and I bought an adapter to convert 16 pin to fiat 3pin
now I want to check my engine and live data in my car I need to know the decent device to use

Assuming you don't have a P90 (i.e. 1.6 sporting) and do have a fire engined one (P55/60/75/85) just download and install IAW-Scan onto a laptop. Its free

Have heard people having issues with IAW-Scan with P85's (1.2 16v) in which case try MultiEcuScan - the free version can read and clear codes, you don't really need the paid version alot of the time
