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.Claudius said: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.
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.Claudius said:The S-AFC is merely a MAF signal corrector.

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 Ludachris said:
For the mildly tuned 320 - 340 hp street Evo, there wont be a huge difference, that's for sure I've been running an E-Manage for quite some time with excellent results.Ludachris said:
