The volume of Ethanol fuel required is significantly higher than raw gas.
Thank you! I will certainly look into that!
A lot of people in the Cadillac V-series world, use Boostane. I have used it for almost 5 years, in my ATS-V and it has worked great. It will turn your O2 sensors a lovely orange color, but I have never had any issues with it otherwise.
A lot of us in the Cadillac V-series world run an ethanol mix, myself included. On ATS-Vs, the fuel system isn't capable of providing the extra volume needed to run a high mixture of ethanol. In order for that to be effective, we upgrade both the high pressure fuel pump and the low pressure fuel pump. Then it requires a flex-fuel sensor to accurately read the mixture, and a tune setup specifically to take advantage of it.

Have you ever checked the ECM’s OAR after a few miles with regular 91 octane on the stock or FP tune?Here is a link to how the explorer st adjusts spark advance. Even stock, it makes sense to maximize this.

I actually forgot to mention that you can use torque pro to measure oar. Had that set up on my 800hp gt500, but not on the RR. You could easily be accurate, but I've not heard anyone bring up this measurement yet for our trucks. Are you aware of any built in way to see this parameter? But the more I look into this, the clearer it is that significant hp gains are possible with this TT 3.0, but not without tuning. Choices now seem to be Ford Performance or using a spare ecm and doing a swap. I kinda promised myself that I wouldn't turn my RR into a money pit(20-30k on shelby) with mods, so I may end up with "merely" the FP tune. But one of the top explorer st modders lives about 10 minutes up the road, so the influence is real. Fwiw, his 2025 ecm is also highly encrypted, so even he hasn't tuned it yet. My bigger concern is with non engine drivetrain components, such as axels, etc. At 5400# plus load, I'm guessing the racers will be finding a lot of weak spots. Over time, our knowledge will start expanding. But until then, these discussions will help flesh things out a bit.
The live OAR value is easily displayed using the FP tuner itself.
That sounds and looks like a perfect first adventure in this truck! Thank you so much for sharing it! I showed it to my wife last night and we are definitely going to head out there soon!!
I am so happy to hear it! I was so impressed that when I got home with the truck, the first thing I did was sign up to this group and make a post about it.
If you’re going, check their website and download their map system. I think it’s called “Avenza maps” or similar? My wife was my navigator and it saved us from going down the wrong trail a few times. It works offline with location services on your device and shows you where you are in real time. Have fun!
