Flashed HR10G to my MSPNP about an hour ago. Went through the MSQ page by page, set it up correctly, fired up on the 2nd keyturn (after I plugged the coils back in
). The control is incredible; I've never been able to get my car to idle this lean.
I seem to be getting a soft-cut rev limiter through most of the range, though, with the occasional blip. Any ideas? There isn't a whole lot of documentation on HR10G for the MSPNP specifically, although I did see Matt/Jerry mentioning something about a .1uF cap somewhere?
Feel free to just link me to something too.
Edit: MSQ added.

yeah, my car would do that a lot on the standard code. After the cap mod it would not do it at all... for a few thousand miles, it started doing it again, and shortly after awhile the car would not run at all, and it turned out to be a bad CAS, so there are at least two things that can cause this problem. More than likely, the cap mod will solve it, It's standard on the new PNP's now I believe.
Check this thread on it here:

Matt, I've never understood why this seems to be more of a problem for people when they migrate to the HR codebase. I just don't see what part of the wheel decoder would be more vulnerable. Do you guys have any inside intel on this?

Cap installed (for everyone else, ceramic capacitors do NOT have polarity, doesn't matter which lead goes where), car is tuned to about 11psi right now. Misfires are gone. I cannot believe how smoothly it runs. Even my roommate (crashnscar) who was manning the laptop commented on how good it SOUNDED.
