I have 3 maps and a valet. Occurs on the least aggressive Map... More so on the others.

Running 93 octane since birth. Not even 91 lol

Mine happens on all maps of mine as well and even when I'm running straight e85 so I don't think it is a fuel type issue. What I think is happening is that when there is load on the engine, the change in AFRs and fuel pressure looks like knocking to the ecuteck programming and you get the flashing light. I'm no expert and I may be overly simplifying it, but that is how it was explained to me.

I find it somewhat odd that the company which wrote the software wouldn't allow for changes in air/fuel or pressure. Seems like you were talked out of a fix?
