MS1/Extra Ignition Hardware Manual

Posted on Feb 6, 2014

The V2. 2 PCB has 4 spare connectors (X11 to X14) these can be used for various inputs and outputs for the following circuits as they are conveniently available on the 37pin DB connector: The V3. 0 PCB has 4 spare connectors (SPR1 to 4) these can be used for various inputs and outputs for the following circuits as they are conveniently available on

the 37pin DB connector: As can be seen, theres no proto area on the V3. 57 and the components are very small. So soldering wires onto the board for spark outputs, hardware options, etc, is going to need a great deal of care. You may even have to remove some parts, which is not easily done to surface mount components, so I don`t feel these manuals should cover doing this, as damage is very easy to do. Also a daughter board will need to be built if you want some of the hardware options as theres no proto area to build on. I have therefore assumed if you bought a V3. 57 that you will not be modifying it to use the hardware functions such as Tacho out, PWM Idle valves, Boost control, Launch input, etc, etc. If you do wish to use these then you will have to build a daughter board of some form to mount the components on. If you use more than 2 spark outputs youll need to use the db15 connector, but ensure you strengthen the traces on the board with copper wire or solder to the pin directly, also connect the outputs in pairs of pins, as per the instructions HERE. Note that the JS0 - JS11 pads are all electrically the same as the V3. 0 PCB as are the SPR1 - 4 pads, so they can be used in the same way as the V3. 0 PCB. The addition is JS12 which is the same as the bottom of R1 on the V3. 0 pcb, but R1 will still need to be removed to use it on the V3. 57, so be very very carefull ! This mode is for use with a single coil distributor...
