Another ECU question.....
 

Besides the sticker on the casing, is there any physical difference between the n350 series ecu and the n370 series ecu? (i'm not talking about what they can do, i just mean how they look). can anyone post pics of both of these without wiring attatched? I'm asking because I have an ecu that the label sticker has been rubbed off. On the side of the unit is says 2307 and below that is 91.8.22 (I assume this is the date it was made... August 22, 1991). Can anyone tell me which ecu it is base on that?

They look the same, you might be able to tell based on the sticker on the chip inside, but I doubt it.
