Impreza fuel pump speed

[Tob7_87]

Hi,

I have a V7 Impreza WRX running modelled fueling on the PNP G4, ID1050x injectors and a Walbro 225 in tank pump.

I am using the default values in the base maps for FP speed, FP Low -> Med 10%FF and FP Med -> High 20%FF. 

Below 10% IDC the pump runs at 66%

Above 10%IDC the pump runs at 33%

Then above 20%IDC the pumps runs at 100%

So during a WOT pull on the dyno from 2000rpm the pump speed starts at 66%, then drops to 33% as the boost beings to build before jumping to 100%.

Something not quite right here as expect the pump should run at 33% below the Low -> Med threshold?

The was an error in one of the old firmwares that caused it to display wrong.  The actual output to the fuel pump works correctly, just it is displayed wrong on screen.

Update your firmware and it will be fixed.
