Rear axle speedo correction

  • Rear axle speedo correction

This nifty little board can be soldered directly in between the wire to the dash of your early 740 to correct the speedometer.

Later 740/940 axles came with a 48 tooth ring, in contrast to the early 12 tooth rings. This board corrects this whilst still providing an output of the 48T signal if you are using a later model LH2.4 ecu.

The reduction is switchable with the dip switch such that other ratio's can also be selected in the scenario you require a different signal for an engine swap.
