Why no E85 tune?

I tried doing some searching but would love to get this forum's opinion on why VW is lacking in the E85 world.

Thoughts?

It's not that it's not big its just that W/M injection has come quite far in this industry and is much easier to come by than E85 around most areas so thats all.

I know some companies have tunes for E85... Eurodyne has an E85 tune for the Frankenturbo... Dave at Autuning has an A3 running E85 with the F23T... pulls like a frieght train.

Fair assessment about W/M. I guess I would be curious to see the gains of a well tuned e85 k04 vs k04+W/M

Stock turbo E85 setup, handles it no problem. I think in the near future, the K04 E85 setup may be a possibility. Will be testing the limits of that soon with new hardware that is set to arrive shortly.
Really excited about this. Love what you guys are doing. Do you have a tune set up for the IHI and e85? Also what hardware are you guys looking at?

Even on a TSi you will need higher flowing injectors and fuel pump. Dave and I were debating this on my car but I drive too much and the loss in fuel economy would be hard for me.

Follow up question... where to get better injectors for the TSI?

Still wasn't able to get an email from you guys.. So I'll try once more.

what ethanol content is your stock turbo e47 file based on? Was the e85 used for developing this file 70% 80% 60% when tested?

Is there a stage 2 software for e47? If so are their any gains over the stage 1+ e47 file?

Is there any draw backs running e47 on the TSI? Besides e85 avilabilty?

unless i'm missing something, the e47 file is 50/50 with 93. The stock turbo gains are not as big. and your gas mileage will drop significantly.

You could advance timing pretty aggressively with it. You're right though, might as well get a K04 or something. Mixing ethanol is a pain in the ass unless you are gaining real power like the jdm or bmw's can

I saw a dyno of a N55 putting down 410whp/460wtq with a couple bolt ons and e30
