Vishnu FlexFuel Kit installed in my 1er

[Dmacc]

Yesterday I took a trip over to fftec to get my long awaited flexfuel kit installed! Right now because my lpfp is on its way out, I'm supposed to stick to nothing more than a 55% mix of e85 and 91, but soon I will be upgrading to the vishnu fuel pump that will be released soon. Once that's out, 100% e85!!! Until then, 55% mix isn't too shabby I've been spinning tires since having the kit installed, My only mods are procede rev 2.5, procedeflash, flexfuel kit, DCI, and Catback exhaust, stock intercooler, stock downpipes, no meth, stock clutch.

I highly suggest you n54's hop on this

awesome. post an update when you get everything installed.

[deploytosave]

just got my rev3 installed, this is my next step!

glad to hear you like it!

More power with less emissions....not sure why your thankful not to have access to that.....do you drive a 128? oh, thats why. lol j/k

but seriously, why?

[Colt]

So can JB4 users use this also? Or is it strictly something in the PROcede unit that makes this work? Can you run plain 93 sometimes or do you have to have e85 mixed in at every fill up?

[geared]

yes. from n54tech:

In some cars when E85 mixtures are used the auto learning may not properly range open loop fueling, triggering false 29F2 fuel pressure codes, and you will need to set it manually. To do this first disable open loop learning by setting FutureUseA = 2. Then start with an open loop setting of 75. If you experience 29F2 codes lower the setting by 5 until they subside. If your fuel trims are stuck over 50, you experience run lean failsafe (2 SES flashes), or encounter frequent 2D25 tuner codes, increase the setting by 5 until they subside. If your high fuel pressure is consistently below 13 when open loop is 75% or higher you likely have a physical fuel pump problem. If you are unable to find a suitable setting to avoid both 29F2 and 2D25 codes you will need to reduce the alcohol content of your fuel (e.g. if mixing in E85 mix in less), lower the all map AFR settings by 50% to lean the air/fuel targets, and/or use a fixed boost map like 1 or 2.

The tune behind the kit involves a new map that basically contains several tunes for each percentage of ethanol detected by the sensor, everything is taken care of for me. All I need to do is go and fill up either with e85, or 91, or 93, and the tune will be able to adjust according to the detected ethanol content.

The JB4 does not use an ethanol sensor, map 5 autolearns your mix by using the knock sensor. Depending on timing and ethanol content, if you start to knock jb4 pulls timing and remembers that the setting before was too aggressive for the mix. This is not an efficient way, nor does it measure actual ethanol content, which is why you don't see the same hp numbers that the procede flexfuel users are putting down from people with the jb4. Because we know the exact percentage of ethanol, procede is now able to offer the most aggressive and safest tune per percentage of ethanol.

I drive a 135i as my sig says. Is that a problem for you?

Why? The benefits, if any, of flex-fuel (ethenol usually) are debatable at best. If you do some searches on the use of ethenol in BMWs you will find the great majority of owners will not use it in their cars. Less emissions, maybe; more power, nope.

I suggest the use of flex-fuel is politically motivated. Corn has better uses.

Are you kidding me!? You clearly have no idea what you're talking about.

I think he was joking for you.

Yes, flex fuel is traditionally motivated by emission standards and politics etc, however vehicles using it can be tuned for some incredible gains.

"On a n54 powered BMW running nothing more than a set of dual cone intakes, expect gains of approximately 140WHP and 140LB-FT when running with an ethanol mixture of at least 60% (approximately 50% E85 and 50% premium grade gasoline). "

Ok I am going to bite on this...

Cobb Stage 2+, downpipes, fmic on 93 octane:



Cobb Stage 2+ E30 beta race map, downpipes, fmic on 93/E85 mix:



Any questions?

runs look good.

In california, where Dmacc and I live, we don't regularly have 93 octane. I am limited to 91 and cobb sport maps. E85 tuning is our alternative.

[Tee-Dub]

Wish we had access to E85 here in the pacific north west too. 92 octane max and E85 is rare as hen's teeth.

And the stations are not really everywhere over here too, also without this kit, you need to manually dial in your tune each time you fill up by data logging every single time you fill up, and we all know how much of a headache that can be.

I been running 50/50 of E85 & 91 mixed on my N55 Jb4 and it run flawlessly. Power gain is noticeable. But I miss the 93/E98 mixed though.

I don't have to do that with my tune...

[Stohlen]

With cobb you'd just switch from an e85 to a 93 map

No, I run Cobb. All I would need to do is switch from a 93 map into the E30 map which is a mix of 93 and E85. Its pretty simple and not some jargon Shiv would like to feed you with.

[MGallop]

im running e85 w/ my jb4 and can feel a nice increase in power as well.
