I know the J&S wont trigger a CE light, and I hear the Apex'i ITC will set off CE lights if retard is more than 5 degrees. It seems that solutions for timing control are $360 - $600 street price, and the new J&S ultra guard looks the coolest for $695.
What Dave is working on will be a simple device to allow for 1, 2 or 3 degrees of retard per pound of boost. Price is not known since development just got started, but it will certainly be more affordable, in keeping with my moto "Best Bang for the Buck".
