Installing vems to a Rover V8 n/a throttle body.

Controlling this and other car´s may require a firmware update. Any strategy proposals are welcome

The current set op on this car is Ms. They use a different way to control this type of “no inlet manifold type.

While running 80 kmt. The map is 80 kpa. And tps. Is 0-2 % so map rices wary fast.

Driving between rally stages (low power) it must use map as the target. While tps rices above 15-20 % tps should take over.

Per´s ides

Rallycar with ITB no turbo. Between stages with little throttle movement 0-1% the car must run MAP controlled in order to have good fuel economy between stages (only 40 L in tank).

As the MAP goes up to 100 and the TPS increases, the TPS table will smoothly take over. (TPS table values increases)

MAP table 0...100 KPa load

TPS table 0...100%

Alpha-N table multiplacive or addiative blending of a MAP table and TPS table.

MAP table with x/y axis as RPM/MAP (table 12x12 or more)

TPS table with x/y axis as RPM/TPS (table 12x12 or more)

Option to control table blending


injector fuel = TPSdot in TPS table x (MAPdot in MAP table x Calculation of injector fuel)

or

injector fuel = TPSdot in TPS table + (MAPdot in MAP table x Calculation of injector fuel)
