Tire rack will stud if you're mail ordering. Some local places still do - mostly north of here. Firestone still makes a traditional snow tire available in 14" that can be studded.
Nice. Was wondering if you ever take it out - and now I know why you hadn't been.
I think if I was going buy a new ECU, my money would go on the 'Hi Rev' unit Rick Eherenberg sells. Still a gamble, but my sense is the odds are better.
I thought about different ECUs and what I might buy. But I figure an old orange box that still works fine is probably going to be the primary and anything else will just be a back up for the trunk tool/parts kit.
