I got an Andea79 A2ZJ710J ROM flashed in a new build with an 04 Sti ECU. It was originally to be on a Cobb Flex Fuel tune but things happened.

The rom input is confusing me. It saying it's a rear O2 input but the references LH TGV signal voltage. I've input the sensor voltage to both but it doesn't seem to blend the maps. I set VE1 to 0 and VE2 to 1.00. while logging VE it logs 0 VE as it should at 0 rpm 14ish psia. Whatever I put in VE1 it logs so I know it's trying to run table1. Now why I think blending isn't working, is that my sensor is outputting .90 volts, so it should be blending 20% table 1 and 2.

So I have two issues, one, no blending. And two, why is Cobb sensor outputting .90 volts (18% ethanol) with regular 93 octane 10% ethanol fuel?

I think it may be working. I gotta finish up a few things like coolant and brake lines, but the map blending ratio started reading after I started the engine. So I guess engine has to be running for blending ratio to show up on logger
