Please help, which ECU is which?

[SR24DET]

I have 2 ECU's. One is auto, one is manual. I don't know which one is which. I took them to the dealer and the guy told me he doesn't know. The serial number on each ecu seems to be gone. I didn't remove it. I need to figure out more so I can order my nistune. Please help.



Here is a pic of the only sticker on each ECU. Please help

info: The auto is off a 91 coupe The manual is off a 93 hatch
