Well, I have my superchips ECU now. I want to get a S-AFC, but am wondering if the gains would be greater with that, or the ECU I have now. Basically the ECU leans out the top end and advances timing accordingly. With the S-AFC I just have conrol over fuel, but not timing. I could probably sell my ECU for a good chunk of what the S-AFC would cost. Which one would be a more practical use for me? Im planning on a rebuild with a large streetport and S5 N/A rotors, so Im thinking this ECU wont really be of much good anymore once I do that.

if you want the SAFC then get the SAFC...

Hands down the s-afc is the best mod i've ever done to my car. If you do install a s-afc, then you can fine tune your car perfectly on a dyno. Although, I would keep the ecu too, as the bump in the timing is pretty helpfull. CJ

Couldnt I just manually advance the timing? As then I could sell the ECU to make up the cost of the S-AFC.

Keep the ECU to do timing but also pick up a used s-afc off ebay (or here or whatever) for like 150 bucks so you can control fuel better.

You can bump the timing. But the ecu probably has a different timing map than the stock ecu has. I'd keep it. CJ

Get the S-AFC...above all It's uses, It allows you to see alot of functions on whats going on In your Motor. i.e Gauges display.

when the megajolt comes out, build that. keep your ECU in the meantime though.
