Haltech elite fuel composition corrections

I have a flex fuel sensor and want to utilize e85. however when i select flex fuel in the fuel tuning tab the fuel correction tables do not populate with any data or axis (see attached) the fuel, ignition and lambda fuel composition correction tables are all the same and set to zero. I am curious if this is something i have to create myself or if there are preset tables that already exsist?

So the table you attached, is by default 0. Its only really required under certain circumstances, which in most cases can be disabled.

What you should have, is some values in the fuel compensation scalar, and if you don't then you can follow the guide from Haltech

Having fuel compensation for ignition i wouldn't worry about until you know that the flex fuel tuning is working ok, and that your AFR's are all looking good. Actually i'd recommend using Lambda only when flex fuel tuning, way easier.

What i also did, is setup a 4D table in the base fuel tuning page and also in the long term fuel trim table.

with values of 0%, 65% and 85% ethanol. this helps you tune but also by doing the same for both base and long term trim, the haltech's closed loop long term fuel correction will work more effectively.

The reason for the 65% and not just 85% is because in winter you can find E85 is actually closer to a 65% ethanol blend, and in summer its closer to 80.

So you now get a table for no ethanol, winter E85, and summer E85. again will make making corrections and tuning easier
