Default E85 on S63tu - 04-08-2017, 04:13 PM

Anyone have any info on running e85 on the s63tu motor?

Both on a jb4 setup and with a flash ECU tune..

I had heard before you couldn't use it on these but Joe I am seeing some guys using it and would like to know more.

Thanks all!

Also want to throw out a huge thank you to Terry at BMS for helping me with my X5M. His customer service is above and beyond in everyway. It's so rare to meet business owners like this at all anymore.

The issue with E85 on the platform is primarily one of fuel trims. The factory flash doesn't have enough fueling range to allow much use. If you add in a back end flash OR add in extra fuel pressure connectors to the JB4, then you can run 30% mixtures without much headache.

Terry is a backend flash something I can do with the jb4? What are the fuel pressure connectorsni can order? That doesn't burn more fuel regularly though when not running e85 right? Sorry for the ignorant questions.

With a 70/30 91 / e85 blend what map and boost levels are being run?

Best,

What are fuel pressure connectors and is this something that'll be worked on for the S63/S63TU JB4 in the future? I know the N54 can run a BEF for varying mixes of E85.

Best,
I've found for the most part that my E70 X5M simply doesn't like running E85 mixtures...it maxes fuel trims and timing goes wonky. At the moment I'm sticking with straight 92 octane and adding meth instead.

I am still curious with adding fuel pressure connectors on my s63tu what I could run on 70/30 91/e85 blend?

If you want to run E85, I'd recommend doing a backend flash as well. Our M5 runs straight E85 (E54 here) with the JB4 and a BM3 flash. Without the flash you will be really limited on the ethanol content you can run. The other option is to run meth as well.

Steve what kind of numbers do you see with that setup? I assume otherwise 91 is the same? No other benefit to the backend flash right? Is that a DME flash?

Best,

Would the M5 BEF be suitable for the X5M?

There's some discussion regarding fueling in this thread > http://n54tech.com/forums/showthread.php?p=532666

I run an E30 mix with 98RON (93AKI) and 107RON E85 - roughly 20L per 85L tank with no issues.

Have you guys made progress on the E85 development for the S63Tu

Best,
They're flashes, yes.

He just said they're running straight E85 on the M5, which is the S63TU .

Your signature says you're driving an F10 535 which is an N54, so are you looking to buy an M5 or something? If so, just know you could also tune the N54 to pretty good numbers for far less.

Terry told me this after seeing my logs running an E30 mix. Apparently my S63 doesn't like running meth on its current setup as my trims and timing go all over the place. This isn't verbatim but Terry said something along the lines of meth will help with the E85 burn.

Confused cause my sig clearly says M5. I also ask for progress cause they haven't updated their E85 M5 development thread for awhile so myself, as well as others, are wanting to see how we accomplish this.

Sorry, didn't edit my post correctly as that question was meant for Skyman.

I am still interested in finding out what the S63TU is making w/ the fuel pressure connectors, backend flash and E85?
