Objective: To modify single function (+ and ) LCI DCT paddles so that they will work on a Pre-LCI Sport or Pre LCI M-Sport wheel – and with a non DCT ‘Steptronic’ transmission. Push/Pull (Dual function) Paddles 3 wires ( 2 for shifting 1 for earth) Pull Only (Single function) Paddles 2 wires (1 for shifting 1 for earth)

Each LCI paddle has two resistors which are positioned differently in both the + and – paddles.

Minus (–) paddle:Resistors are at Top & Centre:

Plus (+) paddle:Resistors are at Bottom & Centre:

Changes required:

First up… the Minus (–) paddle…

1. Remove both Middle andUpper resistors.

2. Now create a ‘short’ using a small connecting wire where the Upper resistor was.

1. Remove both Middle and Lower resistors.

Changes required - cont’d:

Next up… the Plus (+) paddle…

2. Now create a ‘short’ using a small connecting wire where the Lower resistor was.

Minus (–) paddle: Minus (+) paddle:

After completing the resistor mods you then need to move one of the two wires on the connector. The ‘Pin 1’ wire (left of centre) needs to be moved on both connectors to the unused ‘Pin 2’ (or centre location) – that’s it!.

For those more electronically minded, here is a (very rough) schematic of the LCI minus paddle, this explains why I removed one resistor (the 6Kohm) and shorted the other (0.3Kohm) one. With these mods the switch now acts like the original Pre-LCI switch - No more resistance when switch is open and zero resistance when the switch is closed.
