Heyy guys,

Ever heared of a flexfuel map where you can put 98 octane in the tank bit also 102 octane, even mixed.

Heared it will run on the lowest octane leven in the tank when mixed.

Ever heared of it?

You sure not meaning flexfuel in combination with e85?

Vatosbart

Nope, normal gas.

Octane 102 and 98 from a fuell pump for instance

Not Subaru specific, but most OE ECUs will adjust over a 4 RON range, just lower octane than quoted. With the right setup they can adjust fuel, boost, timing to suit. Some E85 flex fuel setups without ethanol content sensors monitor fuel level so they detect a refuel event and use a faster octane learning strategy.

This is avalible but you need to have it set up correctly and have a fuel flew sensor fitted to. Read the Ron of the fuel

Hi there

Depends on ECU as OE ECU not sure if can control or use flexi fuel sensor,but in my view this should and can work too,just you will need to setup this correctly there

Thanks,Jura
