C450 Shifting early with Jb1

would anyone happen to know why my car is shifting early with both map 1 and 2 on the Jb1. It’s shifting at 6300 instead of 6500.

Are logs telling you this or are you just looking at the tach? The analog tach can't keep up with actual RPMs in 1-2 and 2-3 shifts when flat out. If it's logs telling you, not sure...

You have to engage the step down in the pedal to make it rev out in auto. Doesn't really shift at 6500 regardless of doing that, however. Likes to shift ~6400
