This note combines ECE2 theory with UFT216 and UFT261 to show that the equivalence principle of ECE2 is the powerful antisymmetry law (3), which generalizes other equivalence principles and which reduces to the quasi Newtonian equivalence principle (4) under the condition (15) on the spin connection. The Newtonian equivalence principle is a limit of ECE2 and shows that the usual Newtonian equivalence principle is part of a generally covariant unified field theory, ECE2. Zero g force is defined by the condition (19) on the spin connection. The ECE2 gravitational field equations (16) to (19) are quasi Lorentz covariant although the theory is a generally covariant unified field theory. The Minkowski like metric (20) of the Lorentz like theory, when used with the precessing conical section planar orbit (21), gives the deflection due to gravity (33) which to an excellent approximation gives the observed result (4), the famous “twice Newton” result which is due therefore to Cartan geometry with torsion. The incorrect and torsionless Einstein field equation is nowhere used. So the reason for the famous deflection due to gravitation has been found. It is due to a geometry with torsion and curvature. It cannot be explained at all with the Einstein geometry, which has just curvature. The precision of ECE2 is determined by the experimental precision of light deflection due to gravity, which is now very high, and ECE2 is of course preferred because it is mathematically correct , whreas Einstein is mathematically incorrect and not a unified field theory.
