Ethanol flex tune with boost adjustment capability?

[Jeff Hare]

Hi, from what I understand the G4 ecu supports adjusting fuel and ignition timing per % of ethanol.

Are there any plans to also allow the boost pressure to change with a different % of ethanol?

I am very keen to setup a flex fuel tune on my G4 but my car does not like more than 18psi on 98 octane petrol and yet loves ~24psi on E85.  I dont really want to loose that 6psi on E85 to gain the flex fuel capability.

Thanks

This can currently be done if you set one of the boost control tables to be spanned off %ethanol.

It will depend a bit on the existing boost control set up.

If you are in closed loop then it would be a case of having the boost target table spanned of %ethanol.

In open loop mode it would be the WG Dutycycle table.
