You only get CEL on a S14 OBDII . You will not get it on a OBDI car. The idle does drop but not to stall that is a gross over exaggeration of the drop. It usually bumps to about 300 rpm over stock idle and then drops back. If its dropping to a stall point you have other problems as well.

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.

You will get a CEL on an OBD1 S14 too.
