Cost effective, gets the job done, easy to adjust, and is easy to undo if you need to do some warranty work... why would you go with anything else? I'm not trying suggest that nothing else will work - just would like to see some good reasons as to why people would want to go with something other than the AFC.

The S-AFC is merely a MAF signal corrector.
A fully programmable ECU would enable you to gain FULL CONTROL over the entire engine setup, all sensors and parameters. For example, you can set up fuel and ignition tables separately, specify allowed knock level, etc. Changing injectors would then simply mean to enter a different value in the appropriate box in your ECU software, rather than having to retune the whole AFC. Good ECUs like Motec or Pectel will also allow ALS, launch control etc. You can set warning levels for basically any sensor value, where the AFC would just let the engine get too hot for example.
Most importantly, a fully programmable ECU usually comes with 20 x 20 fuel and ign maps, when the S-AFC has to deal with the low spec stock ECU. The processor is also faster and the car runs smoother.

I guess what I was getting at is that its price point is very tough to pass up, especially if you get one from places like Buschur who already have it preset for your setup. If you know what you're doing, you can probably have similar results as a full standalone for a fraction of the price. But you're right, it doesn't have the full flexibility of the standalones. That's one of the sacrifices in its low cost.

Yes you are right on a full standalone unit. I run a Haltech on my GSX I love it. But Just like Luder said in the statement ubove Buscher has the AFC setting ready for a car and they work. Some people are gaining 30 whp on just a AFC upgrade. Myself I will be putting in my own personal wideband O2 sensor in to my car and tunning the AFC to a nate as$. I will run about 11.7 : 1 Air fuel raito.

I totally agree an S-AFC is unbeatable for the low price it costs I guess I was just answering the question "anything better for an Evo than an S-AFC", not taking the price into account... But yes, I started with an S-AFC, too, and it works well and is very cheap. I couldnt think of anything for under $1000 that would enable the same fuel (and ignition) settings an S-AFC can give your Evo

It's probably OK to enter David Buschur's settings. David Buschur is the only US tuner I ever talked to who knows what he's doing. Personally, however, I'd like to double check that the car is running the way I want it to run and I'd monitor the oxygen level in the exhaust gases and also the EGT. I am aware that this involves additionnal costs, but so does buying a 4G63
As for obtaining similar results to those of a well programmed standalone, I would say it depends what sort of power levels we are talking about, and what the car is being used for. For drag racing (I saw a few time slips on here), I doubt an S-AFC could come close to a T6 with departure strategy and ALS For the mildly tuned 320 - 340 hp street Evo, there wont be a huge difference, that's for sure
The afc is definitely awesome for the price. The hks afr is also awesome too. Depends on what you want though. I would recommend a piggyback like an AFC or HKS AFR along with Al's dynoflash. My buddy has the mail in flash along with his hks afr, not yet tuned. He has an upgraded intercooler and pretty much the same mods as me. He definitely pulls hard on me with just the flash.

I've been running an E-Manage for quite some time with excellent results.
310WHP is a bunch of fun in the snow
If a person's goals are around 350 whp (maybe more), for the price, control, and ease to learn; you can't beat an AFC.
I did some AFC tuning on top of a flash a while back. I found it to be a little more difficult than normal.
Staight AFC and no flash.
