When I configure my AEM UEGO with the V8 Scan & Tune software, if I select "Lambda" and go into the setup on the V2, "EQ" is selected. If I select "EQ" then Lambda is setup on the V2.

Either the software generating the .dat or the V2 firmware reading it has these two mixed up.

I am running the following:
Scan and Tune > 8.1.2 - 58
FlashScan > 2.06.12 - 6/9/2009
