Hey, have a safeguard individual knock control system. I am looking to get $350obo. You can control your ignition timing with this unit. Good tuning your timing, or if you want to timing to retard when it hears/see knock.

obo!

 

this can advance the timing also, good for tuning ignition with vafc.

 

I also have a crx hatch for sale black. $20 good glass.
