Interesting PB Info

[maxp]

Was reading about the digifant system, found out the following:

When foot is off the throttle and the car is >1600rpm the fuel position is closed, so if your going down a hill you will save petrol by keeping it in gear. It then comes back on again at < 1300 rpm (i dont know what is happening inbetween?)

The full throttle switch (think this just dumps more petrol in?) is only 'active' > 4000rpm.

closed throttel,   cuts fuel to injectors on overun. 

at full throttel 4000 rpm or there abouts the afm is wide open so the ecu ignores it from that point and goes to map settings
