Oztrack Tuning has created a video
showing the features of EFILives latest custom operating system. Its called OS5.
I have been using it my own car. Its great in a range of ways and newest feature is a special table that controls fueling by throttle position and rpm (below a specified MAP, RPM or Throttle percentage). Its much better
for big cammed cars that jump around a lot in manifold pressure at idle and when transitioning to and from idle.
It also can specify the air fuel ratio at virtually any rpm and manifold pressure rather than just the usual closed loop 14.63:1 or power enrichment in one step. This means progressive fuelling.
The full range of features are displayed in the video atwww.oztracktuning.com/videos/customos5.html
