Hello folks,
Sicne the gas stations here don't sell E85 so I am trying to build a Subaru STi with a dual fuel system.
The main goal is to have good street drive-ability (by using ID1050x injectors as main injectors) and E98 power on demand, anytime I want.
HP goal is around 800~850whp. Turbo is going to be either EFR9180 or Precision 6870...
Here is my plan;
There are going to be 2 sets of fuel rails, total 8 injectors, one fuel system for gasoline and the other for pure ethanol.
Primary fuel system - ID1050x *4, one rail for each bank, feed by an AEM320 pump thru stock gas tank, fuel is RON98
Secondary fuel system - ID2000 *4, one rail for each bank, feed by a huge in-tank brushless fuel pump thru a E100 fuel cell. (or a lift pump + in-line pump)
I wanted to adjust the E% by different boost level. EX;
below 1.5bar of boost - RON98 - using primary fuel system only
1.5~2.0bar of boost - E50 - using both primary and secondary fuel system
above 2.0bar of boost - E100 - using secondary fuel system only
In the mean time, I want to still retain the wideband closed loop lamdba control in auto mode.
With two different VE & IGN maps, ramping by a multi fuel blending ratio, and using staged injection.
Is it possible by using the G4+ Thunder? If I use "modled - multi fuel" equation mode I can't set the parameters of the secondary fuel system.
The "multi fuel" injection parameters seems only correspond to the one(main) fueling system.
Since I am a local Link ECU dealer I really want to finish this project by using LinkG4+. Don't really want to switch to syvecs or motec.
Please help!
Thanks,
