Oops...forgot to mention,
The slower e.t. was due to traction problems...the trap speed was
quicker (not slower). The O2 isn't fully ignored either...there's a
window that the PCM takes a "Snap shot" at.

Subject: DML: Re: Hyper Speed Controller
One thing I don't understand - 14.7:1 under normal cruise is what every
factory vehicle's PCM is doing already. How is the HyperSpeed
controller supposed to help? Furthermore, the factory tunes WOT to be
around 12.5:1 and is non-adjustable especially since the PCM is ignoring
the O2 sensor while in that mode of operation (WOT).
Sounds like snake oil to me.
Bernd, your own track results show a slower ET w/the HyperSpeed
controller in your before/after comparisons.
Track Times:
Before: 14.55 @ 96.01mph
After: 14.65 @ 97.02mph
What gives?
Latr,
Shane
