I know this is beating a dead horse, but from my understanding there are 3 options here to go full e85. I'm not talking tune related. I'm talking hardware related, because obviously all 3 tunes can support this. So the options look like either Vishnus, inline pump or booster(which only works with the procede?), Get a Walbro e85 pump and drop it in place of the LPFP, Or vargas fuel fix(HPFP/Fuel rails) Which do you guys prefer and is it safe to say that anyone of these options have proven them selves yet. I really want to try out 100 E85, as my last step before I upgrade the turbos. Any opinions or advice would be appreciated.

for stock turbos only lpfp is needed. which one up to you. Walbro intank can be a big headache, depends who installs it and how well. inline seems a much better option. Terry is making a diy and there is another one for inline on n54tech. i did the walbro at a shop. got stranded twice but now after 8th time seems its fine.

So in other words the LPFP/e85 mod still isn't fully ironed out right? Maybe I should wait to a better solution is presented.

There are minimal to no proven performance gains past e60 from what I have read.
Inline Walbro LPFP appears to be most reliable current solution to support e60.

any advice for people installing the walbro fuel pump to avoid these headaches?

Interesting, so is it even worth upgrading the pump? Wouldn't an e30 map or even e50 map be fine on a stock pump? One of the main reasons I wanted to go e85 is to avoid the headaches of trying to figure out the mixtures. To be able to just fill her up and go.

You realize you can test your fuel and figure out ethanol content with a syringe, right?

I do it every single time I fill up, since I have been running E85 for the last year in my turbo M3.


BMW makes a very expensive and accurate ethanol detector using a electronic meter and a DVOM, but its like 1800 bucks.


You can do it with a syringe, add water, shake, take measurements. Takes 2 minutes. Hell, BMW used to sell a kit for it.

Just make sure you spray the syringe with silicone to keep it lubricated after use.

The amount of trouble I see from the LPFP in tank upgrade would conclude for me it's not worth it.

Hopefully in the inline is a much more reliable solution.

Jeff, you have to wonder if it is hardware or user error that took 8 tries.

I went through some major fuel system issues with my car, but i was reinventing the wheel practically with my car.

Whose running the Vishnu In-Line $600 pump? Any problems with running 100% E85? Please share your thoughts here.

That's expensive, that's the price of the Vargas fuel solution. Which includes fuel rails and HPFP ungraded if I remember correctly.





That aside I'm in for any solution that works safely and there seems to be none right now. Its leaps forward from where it use to be but doesn't seem like a mod that is done 100% yet as far as I can see still. Or maybe I'm wrong. (I hope I am!)

[enrita]

You need also a flash for 40-50 % upwards.
I can run 100% E85 but doing E50 now

[blisstik]

I haven't seen an official thread about the fuel rail and HPFP, let alone the price. I know $600 is expensive for the inline.

Or you can buy a Procede at half the cost, and get the LPFP - been working great now for a few months.

Actually Vargas doesn't get you either fuel rail nor hpfp. You need to send your own and they just remove material off them. It does not really help you with stock turbos.

First, make sure you really need the upgrade. If you do, go with an inline pump. If you are still fuel limited in the mid range, add meth or decrease your torque target / boost a little in the midrange.

I am getting a Walbro pump installed I'll report back on whether or not I have problems with it.

[zeel]

Been using the in tank walbro without issues for about 8 months now and no issues. Make sure whoever is installing it has skills.

Your procede costs 1/2 of 14 bucks? That's all the syringe costs with instructions from BMW

I've been running the Vishnu inline for around 6-7 months now, I have never had any issues, I'm running 100% right now with no meth.

I've heard of it burning up. It's just the same cheaply made Walbro pump with an expensive install kit. The best option I've seen so far in terms of value, reliability, and ease of install is the Walbro $95 inline pump setup.

Mike

[blisstik]

Any DIYs on that?

Hmmm, so the inline pump is different then the drop in pump that goes in the tank right? Anymore details on this? I know I saw a few threads before on the other forums but I didn't really read into to it. Anyway you can give a briefing on it?
