How can I log several sensors (AFR, temperatures, pressures, RPM) on a laptop?

The Innovate Motorsports modular system is the simplest solution. The basic parts are the LM-2 wideband meter (SKU 3806), the TC-4 Plus 4-channel thermocouple amplifier for EGT/temperatures (SKU 3915) and the SSI-4 Plus 4-channel interface for 0–5 V sensors such as pressure sensors and RPM (SKU 3914). All devices daisy-chain together and the free Innovate software records, displays and analyses the data on a computer. Depending on your sensors you may need extra connection wires.
