stock r32 is fwd until it detects wheelspin then it transfers some power to the rear. opinions differ but its probably around 70/30 max split.
with that controller on it went to full 50/50 split BEFORE the clutch was lifted (works off throttle position) hence it lights the rears up

im having a manual controller fitted now the max is 50/50 but i tell it what to do so i can run it permenant 4wd if i wish..
