As @Micah said, if you post a data log we can help out. It would also be nice to have you upload the exact tune you are using. You can zip it all up and attach it here.

So how's it going? Firstly, what are the ECU error codes? You can read them with Hondata Mobile or FlashPro Manager. Hondata also has a support forum for the 10th gen Civic. http://www.hondata.com/forum/viewforum.php?f=50&sid=99a761a80bc4e5a87bdc66e0fdeed061

Did you fill up with only E85? Typically you want to run E30-E40 in these cars, they will lean out up top otherwise.

I personally shoot for E38.

I also only run e35, but have gone up to e40 without issue. I run on Ktuner, but never had a problem like you have described. I used one of the coolant temperature sensor wires to get into the ECU for ethanol %. Did you do the same thing? The assumption here is your ethanol sensor has been properly wired and you have a flex fuel tune. Please verify you can sense ethanol percentage and have verified it changes with fuel mixture. Tell us the % that you are seeing also.
