I wish...Ok, a few things. I can't really tell that if it is running any better. There almost seems to be a sort of "hesitation" when vtec kicks in at 5000 rpm. The fact that it engages at 5000 rpm instead of 4400 should be a good indication that this is NOT a stock ECU from a '95 GSR like the ebay seller had listed right? Anyway, I think I know why my secondaries aren't opening up. After doing a search, I found this post:

Well, after thinking about it for a minute, I just realized that something had always looked different on my IM compared to my friend's '99 GSR. And I think I finally figured it out. I am pretty sure that I have NO dashpot assembly. It is missing completely from my manifold!
Can someone please verify this?
