Sxi cdi curve

[CARBONX2]

Anyone know how the curve of this cdi compares to that of a SXR?

The 3729 box came only in 1992 750sx. That particular box is very undesirable because it has no retard curve or rev limiter that I could ever find. They will cause detonation with an advance plate and high compression. I never checked the 93-94 3733 boxes but the 3738 box is very good with a 5 degree retard and 8000 rpm limit. These boxes are in 94 XIR, all 750 SXI, and 2003 SXR.
