Interesting EEC test results

[rendyx]

Today I went to test my theory that a B9B in place of my X2J would provide better performance. I yanked the EEC from my 89, only to find it is a L0S reman. headbang So I try that in the 91, wondering if it is slightly different than the L0S spare I have. Here's where it gets weird:

1. L0S reman in 91 causes it to run very poorly, and sound like a diesel. It has no power.
2. Spare new L0S originally in 91 produces the same condition.
3. Upon doing a good reset of the L0S, it runs, but differently. It now is VERY rich, the CEL comes on, and when I try to move, it bogs HORIBBLY and sputters. I turn it off and...
4. Put the X2J back in, with a full reset. Runs fine.

Why would these other EEC's cause such poor conditions, especially the L0S after the reset? Could it be faulty?

For those who wonder what the **** I am doing, I am trying to test that a B9B will provide the best performance.

I don't know, but I hear that a x2J is the one to have. Does anybody know if this is true and why? If not, is there a better one to have? (Stock, lpm, and sctuner) is there also any difference when using these? I know I also heard something about getting a intel x2J over a motorolla x2J. Is there also any difference between these? I would like to clear this up so I don't go picking up anything I don't need. I now have a los.
