Differentiating between ecus

I ended up owning a few t4e ecus. Of the two I'm trying to tell apart, one is from an 07 exige and the other is from an 08 exige. I Only have one in front of me an the model number printed on it is a129e6003f. I think this is the 07. Can anyone confirm for me the code printed on the 08 ecu? Or help me figure this out? Thanks!

Hi!

A/B 129E6003F is the PT# for the 06-07 FED Exige ECU.

All MY2008 and later ECUs for the 2ZZ have PT# A120E6501F, you can't tell by the PT# any longer for which model it was programmed until you know the SW-ID (any std OBD CAN interface can tell this).

Cheers!
Luke
