That's the one I had ordered as well, never could get it to work right. Let me know if you have better luck. Mine seemed to be corrupted somehow. I ended up ordering a full on chip and leaving the shielding off, but I think it'd fit if I put it on, I was just worried about it shorting the old one. Granted now I have a CT60e in my Falcon, so getting the shielding on may be a pain.
