PICTIM Ignition Module
Assembled w/PIC & Tested = $65
Kit w/PIC = $40
(Basic Kit version)
What's a PICTIM? It's a Peripheral Interface Controller Transistorized Ignition Module - fancy words for a microprocessor controlled ignition module. This product is a collaborative effort between S/S Machine & Engineering LLC and Outpost Enterprises LTD - two of the largest providers of ignition modules for model engine enthusiast and builders.
Our goal was to create one 6-12 volt module that can "do it all". Heck, it will even operate on a 9v smoke alarm battery! See this YouTube video --> https://youtu.be/yHBO0y3P4e4
At the heart of the unit is a microprocessor that allows these capabilities:
Dual Mode Operation (Deluxe PICTIM)
Swappable for multiple modes of operation (Basic PICTIM)
Automatic safety shutoff
Efficient operation - minimizes battery consumption
Easy to setup (little to no "dwell" consideration)
Being programmable allows us to support multiple functionality by changing out the microchip (PIC), or with an on-board jumper (Deluxe version). Current PIC offerings are:
SINGLE spark chip, provides one spark for every revolution of the crank or cam shaft
BUZZ chip, provides a "shower" of sparks, ideal for hit & miss or low compression engines
DUAL chip (included in Deluxe PICTIM) does both with an on-board jumper change
Download the PICTIM.pdf below for operation details of each mode (page 5).
Possible future PIC offerings:
an ADVANCE chip, automatic ignition advance timing for higher performance engines
a rev limiter, to prevent an engine from RPM red-lining

Designed for negative ground applications only. The circuit board is approximately 1-1/4" wide by 1-3/4" long. Since many builders connect these to their "points" system, the kit does NOT include a Hall sensor or magnet as these may not be needed. However, if you are not using "points", be sure to order a Hall and magnet from the "Hall sensor and Magnets" section.
For hit & miss engines, order an extra Hall sensor and magnet if you wish to use the "spark saver" option. This feature prevents the ignition from firing while the engine is "coasting", greatly increasing the life of your battery (details included in the instructions).
The final IGBT transistor switches the coil on the NEGATIVE connection, therefore, the ignition battery negative CANNOT be connected to the engine frame when using coils with common ground windings (3-wire connections).
Being micro-processor controlled, this ignition module may be more susceptible to EMI (electro-magnetic interference) from the ignition coil. Be sure to mount coil on the opposite side of the engine from the PICTIM and/or carefully shield the PICTIM from the coil with sheet metal.

We highly recommend you bench test your ignition system before installing it on your engine! See our blog entry for PICTIM bench testing and troubleshooting
