Wired should be essence costly for the first level as it's invasive surgery, with discounts for each additional upgrade as presumably most of the upgrade is accomplished with upgrading the neural interface. Yes some part of levels 2-3 probably involves upgrades of the transmission fibers/superconductors driving the system but honestly the big cost should be upfront.
If you went with a declining scale you would do something like
Wired 1 - Essence 1.5
Wired 2 - Essence 2.5
Wired 3 - Essence 3.25
In addition I'd give wired reflexes the + rating to dodge rating because honestly if you are moving hella fast you should be harder to hit
Further I'd probably make Move By Wire be a modular upgrade for Wired Reflexes as it could easily use the same pathways established by the wired reflexes enhancement. Skill wires would be at reduced essence cost and the whole combo would have a cyberware suite discount.
MBW 1 (Wired 1 = 1.5, SkillWires 2 = .2, Reaction Enhancer 1 = .3) x0.9 = 1.8
MBW 2 (Wired 2 = 2.5, SkillWires 4 = .4, Reaction Enhancer 2 = .6) x0.9 = 3.15
MBW 3 (Wired 3 = 3.25 SkillWires 5 =.5, Reaction Enhancer 3 = .9) x0.9 = 4.185
It's a slight downgrade from by the book because it's incompatible with further levels of reaction enhancer but honestly that's not that big of a deal. The essence discount still makes it worthwhile. Furthermore since you don't have to yank out your wired reflexes but are in effect upgrading a previous investment the upgrade process from Wired to MBW is much less costly in terms of monetary resources.
I'd also give the dodge boost to other forms of IP enhancers (Synaptic, Adept Powers, etc) I'm not sure about giving it for stuff like drugs.
