2014 Mazda Mazda3 S Touring (2.5L) Sedan; DENSO. Automatic only for this year.

Maybe this is a bit too early, but I had sent an electronic mail to the support team and had yet to receive a response. Since my purchase, I have been experimenting different tables to see which one takes into effect. While some tables do go into effect, many others are not budged, and there are unfound tables?

I am trying to properly tune for E20 fuel but find it troubling for it cruise at Lambda 1 (14.7:1) in low to moderate load despite adjustment in the software.
Maybe I am doing something wrong? Could it be because I am using a non-J2534 wire to flash? Or the discovered tables were specifically from the manual transmission ECU (different ROM and configuration; assumption due to the gear ratio default input values)? I like to get this resolved in hope that we can further polish the software for our platform and find more potential!

Non-Working Tables from Personal Vehicle Testing:

• Closed Loop Low Load AFR Target 1

• Closed Loop Low Load AFR Target 2

• Closed Loop Low Load AFR Target 3

• Fuel Enrichment Unk1

• Fuel Enrichment Unk 2

• Volumetric Efficiency 1

• Volumetric Efficiency 2

• Volumetric Efficiency 3

• Volumetric Efficiency 4

There could be more non-working tables, but these are the important changes for my application.

Anyone having similar experience?
