Jumpers are used on the ECU to tell the microcontroller to read from either factory code
(located in a memory chip on the ECU main board) or from the Nistune daughterboard. You will
need to move the jumper on the ECU so that it will read from the Nistune board

The easiest way to move the jumper is to melt the solder on both ends at once by using the de-
soldering iron one end and soldering iron the other. Use tweezers to remove the jumper and
reposition to where required as per instructions below.

Jumper positions will vary depending which ECU you are fitting the Nistune Type 5 board to.
The following sections indicate which jumpers to fit according to ECU type.
