Re: Using an electronic speedo with TBI and 700R4?

If you are using a stock tire size that was available in 1988, and know that axle ratio, I have a GM pamphlet that shows that DRAC calibration / “divide ratio” of factory equipped vehicles.

Did you give the model, year, engine, fuel system type, and transmission information?
If it is modified from what came stock from the factory, let us know that too.
