So my original ECU was a ARJT and the current one that is in it is a ASDU.

When I swapped to a NV4500 I told the guy who burned a different chip for me that I had a ARJT but in reality it is a ASDU.

I just received all my OBD1 scan/burn stuff (Moates 2 and some other odds and ends) and started reading here to become familiar with it and noticed the discrepancy in my ECU.

Is this an issue?

What are the applications for the two? Obviously the .bin is different, but with two different BCC's, should be something significant like engine displacement, trans used, emissions class, rear gear ratio, some other potential drivetrain differences I'm probably forgetting.
