No need for that unless you are FI.
2001semax: The best way to determine if you need the E-Manage is to dyno. Be sure to get your Air/Fuel measured. If you are way off, then you will need to get either the E-Manage or the S-AFC. Personally speaking, the E-Manage costs more up-front, but will definitely out-shine the S-AFC in almost every arena, with the exception of the "looks-good" category. If you add a mod, then you'd need to dyno again. You'll eventually learn that the dyno is a tool that you use to tune the car, not to see what the car can do. Once the car is tuned, then and only then should you make a run that will show what your car can do.
And for all of those who say you don't need it... you can't predict the ECU's adjustments. I've been able to squeeze 20+ HP out of the "defective Stillen headers" at certain intervals because of tuning. And the car needed the E-Manage before the headers went on.
I drove my car 900+ miles with the A/F ratio at 9:1 before I actually dyno'd. I got about 8-11 MPG too, depending on where I drove it. And the car only had a CAI and 2.5" exhaust (from the Y-pipe back). So there is definitely a use for it on a NA car, but ONLY a dyno with wideband readings will determine IF you need the E-Manage or S-AFC.
I will agree with one thing... to be the most cost-effective mod, you should, in most cases, wait until you have all your mods on. Personally, I grow money on a tree in my backyard, so I dyno after every mod. This is because I want the car in top-shape all the time. But since my money tree can't be bought at your local Lowes or Home Depot, you may choose to save your hard-earned money and wait until your NA mods are done, then dyno and tune.

Studman,
I'm close to deciding between Greddy E Manage and the Apexi SAFC II. I have some more research to do but I see you prefer the E Manage. I've found some guidance on installing the SAFC on the Maxima but I don't remember reading about the E Manage.
Some questions...if you don't mind.
What other components do I need beside the main E-Manage unit?
Can you provide any guidance on installing the E-Manage? (I'll search your previous posts and your homepage for some info).
I keep hearing about burnt coils associated with the E-Manage. Admittedly I have not fully read those threads because I didn't think I would need an engine management unit, but is this something I would need to be aware of?
Thanks for any help you could provide.

Until you start swapping injectors, cams, turbocharging and supercharging at "high" levels, swapping mafs, etc. ENGINE MANAGEMENT IS A FUN LITTLE TOY TO WASTE MONEY ON

I wonder why the fastest (trap speed), and quickest (ET) fifth gens don't even use an afc or e-manage, same for the fastest 4th gen Until you start swapping injectors, cams, turbocharging and supercharging at "high" levels, swapping mafs, etc. ENGINE MANAGEMENT IS A FUN LITTLE TOY TO WASTE MONEY ON
