I have an old OBD-II interface that I am no longer using. Long story short, this interface is custom programmed for Subarus and has to be "married" to a single car. Unfortunately, the ECU on my car took a dump (due to dead battery), so this unit is, essentially, useless to its normal target audience. However, I know we have a bunch of electricians and tinkerers here, who might like to mess around with it and (possibly?) reprogram it.
Anyway, it's already prepacked and ready to go. All I ask is a prepaid shipping label, and I'll send it out ASAP. The box weighs ~2 lbs.
