This is a new version of the stimulator originally designed by James Murray (jsmcortina on the forums) that expands on the original stim's features. The main improvement comes with the addition of a microcontroller which allows the simulation of up to 62 different toothed wheels in addition to the standard distributor signal of the old stim. At the moment, there are 43 programmed wheel patterns but the firmware is upgradable using a specific USB cable.
Now with v2.x firmware. Supports new wheel modes and remote control via MegaTune or TunerStudio.
