i dont even know if there is a difference between the DX and STD other than the tranny...the motors are 100% identical..but the DX is rated at 92 hp the STD is rated at like 72...i think its all the same , honda just rated the STD lower so they sell the DX better.

STD had the cat on the header. I don't know if that is enough to choke the STD down 20 hp or so.

I tried this too...took the ECU out of a 88 CRX DX w/D15B2 auto and plugged it into my 91 Std hatch w/D15B1 4 speed...didn't seem to make any difference,and wouldn't idle correctly...probably because the Rex ECU was auto and my car is manual...oh well,I was curious.I think the exta 21 horsepower the B2 gets is probably in the design of the head and maybe a more aggresive cam ?
