Innovate SSI-4 (4 Channel Simple Sensor Interface)

The SSI-4 device is a simple sensor interface that adds 4 inputs to an MTS Log Chain. The SSI-4 may also be used as a stand-alone device for logging data directly into a laptop with the included LogWorks software or it can be used in conjunction with any other MTS compliant device.

Channel 1 is a direct RPM input by default, and can also be configured for external 0-5V, frequency, or spark reference for ignition timing measurement. Channels 2-4 are configured to digitize external 0-5V analog signals by default. Channel 2 can directly measure frequency (like driveshaft speed) or duty cycle (for injectors). Channel 3 can measure RPM from a VR (variable reluctance) sensor, and can also be set up for ignition timing crank angle reference ( trigger wheels) or frequency. Input 4 defaults to digitizing external 0-5V analog signals, but can also be configured as a frequency input.
The SSI-4 is also a key component of Innovate Motorsports' Modular Tuning System (MTS). Using the SSI-4's serial ports you can daisy-chain other Innovate devices such as the XD-16, AuxBox (LMA-3), LC-1, DL-32, and TC-4.

The SSI-4 includes the SSI-4, Program Cable, Patch Cable (to daisy chain with other MTS compatible devices), Mounting hardware, and cd which includes software and manuals.
