which ecu ?

i picked up a 2003 g35 im and not able to get to my car untill the weekend as its not stored at my house and i work thru the week , but im trying to determine if i have the unsupported ECU for the early 2003 or the tunable one .. i read that if the car has a manual clutch fan then you have the bullshit ecu .. can anyone confirm this ? thanks

Take off the passenger side components and get the numbers off the ECU then you'll know, or just look at the ECU harness, they have a different shape. Here's the pin layout for the newer style, the older one has a MUCH different pin layout.
