Here is a before PCM tuning and then after tuning to reduce knock counts and to increase timing for good WOT performance.

Before, see lousy low timing
Low Timing

Frame by Frame analyzing of O2 cycle

Reducing knock

[Linked Image]

Timing differences just going a few percent of A/F ratio

As you can see we went from a low average timing to lower amoount of knock and very good timing at WOT.

Blackwing, 30# inj. and MAFT. Tuning with Ease now results to follow. The Ease is well worth money, I now see why John recommended it as the best way to tune.
