ECU CHIP FOR G35 COUPE
any suggestions on which chip i should get???

 

There aren't "chips" for our ECU....

do some searching...
look into TUNING OPTIONS.

 

^^ He is right but you can buy the utec,osiris or the cobb and get them tuned but try a little searching first.

 

Please search this topic, as there is a large amount of information on them.

The "chips" you might be referring to are either ECU reflashes (such as UpRev Osiris, Technosquare, etc) , EMS piggybacks (such as UTEC or FCON-iS), or standalone units (i.e. Haltech, FCON V-pro, etc).
