Guys, the E-Mange now has all the features to completely tune your car. They have now added fuel target maps(closed loop) and other functionality that makes it a viable solution to the DME options. A little more expensive(not much more) than MegaSquirt, but it's plug and play and you don't have to build it or re-program it :) Can use WB O2 and has timing changing also.

Is there any way to directly control Timing or Fuel? or can E-Manage only intercept the sensors and trick the stock ecu(piggyback)?

As far as I can tell, and I've been on their message board digest for ~8 months is that it can only change the incomming signals, it's not a "stand alone". With that said, it can easily support 500+hp with the existing DME.

There are a few people in the Nissan community I know running e-manage and its an ok unit, but it has some issues. Fortunately there are tons of management options there. However, Im not sure how much of these holds true for the ultimate, but I would think that its very similar. When adjusting timing for instance, what you see in the tables are correction values only, not raw timing figures, so you still need to know what kind of timing the DME is running to accurately write a map. Without knowing what the base timing values are, it can be sorta hit or miss. Fuel correction values also in essence, trick the ecu into a different load area of the map, which if you are removing fuel, also advances timing, which my not be what you want if you are trying to map for a FI setup. I do like the fact that you can delete the AFM and run a MAP sensor. It definitely seems to be a viable option for someone who doesnt feel like tackling writing full maps to get the car running using a full standalone.

Right, for an NA car, you wouldn't use an E-mangae. It's almost exclusively for large power adders, SC, Turbo, Strokers etc. That way your only tuning the E-Manage while under boost. This means only ~25% of the DME map area. And yes, you still have to tune the car from the base DME maps, but with forced induction, you'll almost always just be adding a fuel % and retarding timing, so that simplifies matters alot. Atleast with the M30, you don't need a O2 clamp, as it's ignored anywhere the E-Manage would be used.

To reiterate, you do have to tune the system either on a dyno or street, but thats true with any piggyback or stand alone, but at least you don't have to recreate the wheel, so to speak.
