Interesting. Are the gains meaningful? I run meth on my turbo car and while its good for some power it's more to keep intake temps down.

I run meth on my turbo 99M3 for octane consistency and some cooling, but that car is tuned for 93 pump and the meth is not factored in.

On the 08M3, I run a Vishnu Procede with meth. It provides octane enhancement and some cooling and the car is tuned for it. I don’t have any dynos but it has been on the car for about 4 years. It supposedly comparable to running 100 octane race gas. Timing target goes from 32 to 37 degrees. Stock cars often don’t hit the 32 due to knock. There are a couple of threads on the Vishnu from about 4 years ago. I think it could add 5-10 rwhp.

S65 DME "Flex-Fuel" support is possible if someone puts the effort into it.

MHD has a flash available for the N54 that uses a GM Ethanol Sensor, pinned to the DME, which allows for timing/fueling blends based on measured ethanol% (and target boost changes).

I hope someday a developer will figure it out for the S65. The time it takes to integrate new functions into the DME logic, test/develop loop, and beta, is a daunting task for a very niche demand on an aging platform.

[pbonsalb]

That would be awesome.

Shot them an email, to see what they have to say about it; and maybe seeing what they think of the MSS60 platform.

That's pretty neat, Ill share any findings.

That would be amazing if it gets developed for the S65 DME!

If it does, I'm also hoping it's available to the mass market and not like a unicorn TT S65 setup.

The only way to get "flex fuel" for the s65 so far is the AFD kit, yes you can mock something up but a kit that comes out of the box with the exact parts and a direct fit to everything/no mocking up or customization is the AFD kit, which I had running on my Z4 M. Gintani makes their own full e85 tune for the e9x M3 which is the most powerful tune on the market and no flex fuel computer is needed, just flash their tune and go fill up full e85 at the pump.

Heard back from MHD this morning. Disappointing news... Short and sweet.

"Hi
no sorry, no plans for any further E series model. "

Would for sure be neat to be able to pin out strait to DME and add the flexfuel sensor!

The eflex kit comes out of the box plug n play ready fyi. Inector connectors and plugs all fit just like afd. Side by side it looks nearly identical to the afd kit except for the shape of the commander. Also, the eflex app monitors more functions than does the afd app, which I thought was hilarious given the price difference.

AFD strikes back!

15% OFF SALE on any PROFLEX Commander system with code REFUND15 now through April 17th. Everyone knows tax refunds are for car parts, so make your refund go further and your car go faster with the PROFLEX Commander plug-and-play performance flex fuel system and E85!

Thanks for the heads up. With the 15% off, the AFD kit is $1020 versus the Eflexfuel kit is $347 (after conversion to USD and excluding VAT)

Someone is making a lot of money marketing to BMW owners used to paying the M tax who don’t work on their own cars.

Bingo. There are guys on mbworld that take the car in just to install an intake. And coincidentally, the afd kit for the c63 is $1600

I'm really tempted to buy the Eflexfuel kit. Dammit I wish at least 1 or 2 people had feedback for the S65 community

[Doc Oc]

Be one of those people

Exactly. On 91 octane the stock ECU is pulling timing, even moreso as IATs rise.

The Meth will allow the ECU to actually hit timing targets, and, hit them consistently even in warmer weather. This is due to increased octane and its cooling affect, without any tuning changes. It would be akin to driving your car on a cold night.... imagine it running that good all the time.

I am very intrigued by a standalone meth kit (no tune) but not sure one exists for NA cars. The Vishnu seems to require their piggyback which I'm not sure how I feel about - the company seems sketchy. Are they even still around? Is there a standalone Meth kit that isn't boost-triggered that can work with these cars?

Or is E85 the way to go here? That wouldn't be convenient as there are almost no E85 stations in San Diego.

Vishnu is NLA. Aquamist makes great kits but no interface with the ECU, unlike the Vishnu. Probably running a few gallons of E85 per tank would work. I think a few people do that. You can find their posts.

Did you check this site for them?

There's plenty in San Diego, go to Pearson fuel website or the app. Probably about 20 throughout the county

You're right.... bad searching skills on my part this morning. About 20 give or take and one near me as well.

4 gallons of 105 E85 mixed with 12 gallons of 91 would be a combined tank octane rating of ~94. This is probably what the S65 needs to consistently hit full timing targets in warm weather, I bet.

Heads up that it's $399 on ebay but $347 if you buy from their website directly.
