Using a Automatic ECU on a 5 speed swapped S13 or on any S13 is a little stealth upgrade. Like what was said above it raises the rev limit, eliminates the speed cut and has a slightly different timing curve and fuel map. This is due to having to push a Torque converter. Hence why it turns into a performance upgrade for 5 speed cars.
I always leave the auto ecu in on 5 speed swaps on S13 because of this.

That's from this thread,

As for fuel maps and better mileage idk its all based on what others say but it seems to be common knowledge. I get 25mpg out of a Convertible(think heavy car) with the auto ecu but it also feels like it pulls harder then my friends factory manual. As for the light, I don't get one on my S13 and I passed smog in California with it.
