e-manage: ultimate vs. original, What does ultimate bring to the table. Options

[epinasty]

So i need some fuel management among other things and it seems that splurging for the
e-manage would be better than safc2. I guess i can tune the timing and fuel with the e-manage without any extra harnesses. Does anyone out there know what the e-m ultimate has out of the box that the
original doesn't. If im cutting out the middle man and going for a piggy-back should i just continue the funds dump and get the ultimate or is that just overkill for a newbie trying his hand at tunning.
I have a 5sfte to manage btw.

So with the a/f target maping i could just set a ratio i want and the
unit will try to keep the engine running there??
Hey for a guy with no tunning experience that sounds good.
Anyone have either of these and can give some insight on what each can actually do without harnesses. I can read the vauge greddy explination but i don't actually know what the unit is like. If you use the support tool do you think i could learn to tune this properly or should i just find a dyno?
Wannabe, know any dyno's in the witchita area?
