N54s limped like crazy early on in piggyback days. That is a Siemens ECU and will limp based on fault (boost, timing, etc)
Grambles is talking about knock retard, and that shouldn't induce a limp mode. It's just the ECU reacting to fuel behind the scenes.
DO NOT run E85 on a race gas map. They aren't mapped even close to the same.
I know our cars can be mapped for E85, I'm pretty sure I saw an E85 dyno graph on a 2.0T car when I was at APR last week.
In terms of octane variance? e85 runs pretty close to 110 from my research.

No. In terms of air fuel mixture. E85 means the engine should be run way richer. This is why it's consumption is much higher. An e85 map is unique.

I'm just wondering if there is a margin UNTIL the ECU steps in an implements a safety measure, IE: Limp Mode.

I'd say no, becauae its not necessary. I'm not gonna run my race gas map on pump fuel to find out, though. Lol.

Me too i will foresee threads in the future with the title of " switched tunes from APR to Unitronic to APR and back to Unitronic. :thumbup:
If you purchase an APR tune and are having driveability issues or others, you have 30 days to get a full refund if you are unsatisfied. There is also customer support to help you.
If you switch from one tuner to another tune in an attempt to increase power, it may possibly be the most expensive horsepowers you ever buy, and that is assuming you even gain any power. Spend the money on a better intercooler, W/M, or save it for your next turbo upgrade.
All the guys that go this route have confirmation bias, and is why they have
"OMG Unitronics what a difference so much more power" in their signature to profess this. lol.

Sometimes it isn't about horsepower but rather power delivery.
You sound like you work for APR.
