The ER has a taller final drive gear I think, (3.52), the non ER has 4.11
The ER has only two piston rings, one compression ring, one oil ring.
the ER has a shift-point indicator on the instrument cluster, with sensors on the transmission for this.
Might be a difference in cams and the ECU too.
Generally, the ER gets about 15-20% better fuel economy, than the standard model, maybe partly because they do not come with Air Conditioning either.
