I have both of these ECU's and am wondering what one is the best to use. My Civic is a 1992 Hatchback with a B20B and Si five speed tranny. Let me know what one will be the best out of the two to use with my setup.

Well, I thought I would ask. I thought someone has told me before that there was a slight difference in the two. However, sounds right to me that there might be no big difference since there basically the same.

yup, pretty much the same thing. the ls got the pr4, the gs got the p74, both replaced with the p75 in 94.
