Product Description

The regular JimStim can test the main board on your MS3. But what if you’d like to see the inputs and outputs on the MS3X expansion card in action, too? Now it’s easy – just add a JimStimX! Use the three pull-off jumpers on the JimStim to connect the 5 volt power, ground, and cam signal to the JimStimX, and you can test the outputs with the LEDs and use the DIP switch and three trim pots to control the four on/off and three analog inputs.

This build it yourself kit includes everything you need to put a JimStimX together except the solder. Everything is included in the same pre-labeled bag styles we use in our MegaSquirt kits.

Requires a JimStim for proper operation, sold separately.

Do I use this board or a regular JimStim to test an MS3?

  • You would use both of these boards, connected with jumper wires. The JimStim plugs into the main board connector, while this board connects to the MS3X.
