Here's an example of the advanced capabilities of the 1bar Speed Density Enhanced option in use on a large camshaft naturally aspirated stroker engine fitted with an 8 throttle body intake (courtesy Sam's Performance). This engine exhibits the classic symptom of a large duration (270+), sub 108 lobe center camshaft: low idle vacuum. It also shows erratic and fast moving MAP readings, where just 2-3% throttle application results in MAP heading over 80kPa even at substantial engine speeds. This results in similar zones of the VE table being hit under different driving conditions and also gives very little tuning freedom for fueling in the available MAP ranges. This is where the new VE Multiplier table plays an important role.
The new VE Multiplier table adds throttle position as a new dimension to tuning these engines. You can now adjust the VE table result at different TPS and RPM conditions and therefore eliminate troublesome fueling issues.
