Interesting that you mention ignition coils. I polled the Forced Induction section a while back after noticing how many people were making huge power on stock LS1/LS6 coils, and the majority response was "the stock coils are fine". Meanwhile over on LS1Tech, D585 coils are regularly pushed as what everyone should upgrade to. People are buying sets of them cheap at the junkyard and acting like they struck gold, trying to sell them in the Classifieds for $100. Yes, I am aware of the Megasquirt testing, but I haven't really found many real-world "I had a problem with LS1 coils and D585s fixed it" stories to back up the bench test results.
This is the first time I've seen the D585s associated with Flexfuel though. If GM spec'd those coils on Flexfuel trucks specifically, maybe there's something to that.
I’m still take the connectors to injector stack harness route and adding this controller it regulates cold starts temps you can mix any content! Among some other things. Some great write up though keep um coming in!

These are not mine, but this is is what the folks do over on the LS1tech site do;
