	Fueling change with E85 « on: September 02, 2014, 10:55:31 AM »

I got a fueling question as well.
My idle LTFTs are within 1% as before, but my pt LTFTs are +16% now. They were +5% before.
Differnce is I got E85 now and slightly bigger turbos then my OEM k04s and e70 I had before.
Is it bigger turbos or diff in % of Ethanol that is reason for this?
What would be the best approach tuning this?

I was thinking tuning KFKHFM.
Mine are currently 1.024 across the board.
Does this mean reacher then 1 or leaner? If i increase it by 10% to 1.1264. That would be right?

Split into a new thread... did not belong in original thread.

KRKTE is one place to start if you are switching to E85.

In 2 month it will be e70 again.
Maybe it should be best to aim for a value in-between e85 and e 70?
How about those values in KFKHFM?
If i would increase fuel, would values be .9 or 1+

I would not do that. That will change load.

Changing KRKTE would affect my idle LTFTs which are perfect now, and then I will have to change my TVUB as well?
Is this really the best approach?
How about FKKVS?

Changing KRKTE will have negligible effects on idle trims.
