does it measure rwhp? afr?
edit- didnt see you edited your post.
Why AFR jumps so much at 5100rpms?
Ignore everything after 5000 rpm, Rudy stopped the test there and so the AFR jumps up. After we tie the car down (next time) we will run the test right up to 7000 or so. We were not really interested in measuring max hp today.
