Steeda timing adjuster.
 

Anyone have one, or can explain how they work? I'm totally confused, and I think I found a decent deal on one.

Help.

It allows you the ability to advance your timing by moving the location of the crank trigger forward or backwards. The trigger picks up the gap in the timing wheel which indications top dead center and by moving forward it advances timing and backwards retards timing. 14-15* seems to be the best settings, at least it picked up 9.2RWHP on the dyno for my car.

Mustang92 hit it on the head. Their very useful to have on modular cars and you can adjust the timing fairly easily and quick to.
