Club Spec 4S steering wheel auxiliary system

Club Spec 4S steering wheel auxiliary system

Aimed at the Club and Professional Motorsport Racer, and everyday car user, a system designed to eliminate the need for any direct cabling from your Steering Wheel buttons to your peripherals.

The Club Spec 4S uses short range radio frequencies (RF) to ensure that a clear, uninterrupted signal is passed from your Steering Wheel Buttons to the Receiver Module irrespective of mounting position.

Unlike Infra Red, the system requires no line of sight, so it can be placed under the dashboard and out of sight. The Club Spec 4S features a black, professionally finished - incredibly light and strong FR4 PCB Button Panel Assembly with 4 coloured buttons pre-installed.

The X-Monitor SP1 large Digit timer is integrated right into the button plate with a separate dedicated button, and a selectable 12 volt 4 Channel Receiver Module thats capable of switching the 10 amp relays into three different states. You can select ALL momentary, ALL latching or 2 Momentary and 2 Latching.

Apexi model info

Apexi release the Power FC ECU in three different flavours:

1. 414-Z001 (FD3S1) - this fitted the 1995-1998 fd's.
2. 414-Z002 (FD3S2) - this fitted the 1991-1995 fd's.
3. 414-Z003 (FD3S3) - this fitted the 1998 on fd's.

After a short while Apexi then upgraded the software version and made the chip in the ECU soldered non-removable, unlike those above where the chip was a pin type and could be removed.


Apexi re-released the Power Fc's serving the same purposes but with different serial and part numbers:

4. 414-Z004 (FD3S4) - this fitted the 1991-1995 fd's.
5. 414-Z005 (FD3S5) - this fitted the 1995-1998 fd's.
6. 414-Z006 (FD3S6) - this fitted the 1998 on fd's.

Nowadays you will find that all new power fc's sold new are one of the three later models. The most common over here is the 414-Z004 this is simply due to the fact that there are more 1991-1995 cars out there.

COMMANDER (this is generally where people get confused)

With each of the models of Power Fc that Apexi released the provided a hand held interface module called the Commander. With the commander you could read/monitor all the parameters that were accesable through the Apexi Power FC ECU. The commander also gives the ability to Write SOME commands to the ECU (for full mapping capabilities a specific software package is required, this is called DATALOGIT).
