Dunno about the sport light, but if you have an SL then it's fwd. AWD in US-spec cars was only on VR4's and Stealth RT/TT's. ECS is the Electronically Controlled Suspension. Taken from this site (
http://www.us3s.org/freeforum/showthread.php?t=3581 ) Electronic Controlled Suspension (ECS)
"It is a system using electronicly adjustable struts. Discs in the struts turn to open or close holes to increase or decrease resistance. A user can select from Tour (soft) or Sport (hard).
The system also uses G force sensors and a steering sensor to auto switch modes depending on terain and rate of turns.
In Tour it can auto select from soft, medium, and hard."
I'm sure some other guys(*ahem* Stealthee) can chime in on your technical issues.
