This is true to a point sense, but with the injector correction with the injector harness bypasses what the ECU is doing with the injectors.

That's a bit pessmistic, do you have any threads where anyone has documented their experiences good or bad with the e-manage?

Also, the 400-600 you see these things sell for is just for the unit, if you look into all the extra accessories that you need and add that into the cost, you're looking at 700-800. If it were me...i wouldn't pay 800 just to be restricted to the ECU, i'd rather save the extra few hundred to get the proper EMS.

You can pretty much get an E-Manage blue with injector and ignition harness for about $360. Most reputable tuners have the e-manage tool these days to program it which is an additional $100.
The E-Manage Ultimate is still a tad bit expensive, you can find the unit for $550 and the harness for about $75 which is a total of $620 for the full solution since the E-Manage Ultimate comes with the CD already.
While I completely agree replacing your ECU or flashing your ECU is the ideal situation, not everyone's power requirements call for doing such a thing where a piggyback would suffice to dramatically make a huge impact with controlling injectors and timing.
IMHO I feel that S-AFC is a toy and should only be used on BPU setups such as naturally aspirated situations where your just installing intake/headers/exhaust etc. It's probably not best to be using the S-AFC on a turbo vehicle because manipulating your air flow signal excessively will undoubtedly have an impact on other things your ECU does.
We have the e-manage blue and e-manage ultimate installed on turbo converted eclipses, turbo suzuki swifts, turbo charged Toyota land cruiser we've yet to find a vehicle that it does not work good on. I am going to install one on my MR2 when I'm ready. Primarily I just want to get that air meter out of there.
