Title: Fueling change with E85 Post by: Lost 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?

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

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+ Title: Re: Fueling change with E85 Post by: nyet on September 02, 2014, 10:21:16 PM How about those values in KFKHFM? I would not do that. That will change load. Title: Re: Fueling change with E85 Post by: Lost on September 02, 2014, 11:52:13 PM 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?

Is this really the best approach? How about FKKVS? Changing KRKTE will have negligible effects on idle trims.

Once my engine is run in and wb02 connected I will look into it. |
