48-2 " Gear Down"
One method, the one I use, is an Oil Pump Drive with a
48-2 target inside.
The apperance of the distributor is retained, though the cap is missing in some cases.
When this item is fitted, sequential coil (8) AND injectors (8) are controlled by only ONE hall sensor inside the OPD.
The "Gear-Down" 48-2 target would be the same as 24-1
ON THE CRANK.
Yes, we measure the tooth accelaration which allows for a more accurate "spark instant".
