Whats the difference between a safc and ecu?
Is there a difference between purchasing a safc and a upgraded ecu besides the price? They both seem to do the same thing, a/f ratio and timing, except the ecu removes rev limit.

"A peformance ECU advances the timing and remaps the air-to-fuel ratio throughout the RPM range. It also removes the speed limiter. "

Isnt that the same thing a air/fuel controller does?

No, like he just said, you can't control timing directly with the SAFC. SAFC stands for Super Air Fuel Controller. It doesn't change timing directly.
