Trivia Question........anyone know what this Vette Doctors Black Box is?

I guess if you could ID the exact pins on the ecm it is spliced in series with, you could probably figure out what it is doing. A speedo pulse box sounds likely if you have a different gear ratio.

I've got one of those boxes too, so I would be interested to hear what you learn about it. Car had a lot of work done by VD and it does have 4.10s.

Thanks guys, I'll start tracing things down if they don't have any info. I just find it hard to believe that something this complex is to correct the speedo. I had one in my 1993 Firehawk from around 2000 and iit was so much simpler.

The reason I thought it might be related to the gear swap,is that 4.27's were installed. In 1998,the ratio choices were 3.92,4.09,and 4.27. The new Super 44 ring & pinions weren't available,yet.

I believe you are probably right Clint since you know these cars better than most. It will be interesting to hear from Vette Doctors next week.

Talked with Vette Doctors today.........drum roll please

It's for adjusting the speedo after a gear change.....I was shocked!

Clint was right and the best thing about it is they remembered the car.

You have a great car,Tony. Hope you enjoy it as much as you can.
