The CANEGT 8 Channel Thermocouple Interface allows you to monitor up to 8 K-type thermocouples AND up to 8 Innovate wideband devices over an Innovate Log Chain, and can transmit the data to a MegaSquirt-II, MegaSquirt-III, MicroSquirt, MSPNP, or MS3Pro over the CAN bus, so you don’t use up any analog inputs for these. It can also transmit its data to a laptop directly over USB, or send a 0-5 volt signal based on the thermocouple inputs to work with external gauges.
The CANEGT allows Mike Dusold, Holley LS Fest Grand Champion and Optima Ultimate Street Car top-3 contender to receive 8 runner exhaust gas temperature data to his MS3Pro EVO, which runs closed loop fuel & spark corrections per cylinder! This leaves 7 analog inputs for his power management & sub-systems!
‘Multi-channel EGT systems add another dimension. “Generally speaking, one looks for consistency between cylinders, because any noticeable variation means that the cylinder that is out of step with the rest has some sort of problem like a flow blockage, an inner chamber variation, or a cam lobe shift that is causing the odd EGT,” Eyres explains. “On an EFI engine, a simple fuel rate change to the ‘out of step’ cylinder will aid in detecting the cause of the variation by either confirming or rejecting fuel (and air) flow variation as the cause.”
CANEGT 8 Channel Thermocouple Interface Features:

- Measures both exhaust gas and cylinder head temperature
- 8 analog 0-5 volt outputs
- CANbus connection for connecting to MegaSquirt
- RS232 connection that conects to an Innovate LogChain – currently supports up to 8 Innovate wideband O2 sensors
- USB port for laptop connection
- Multiple CAN-EGT units can be daisy chained together

Mounting dimensions are approximately 1.5″ tall, 3.5″ long (including terminal blocks), 4″ wide.
Serial connection uses the older, barrel-style Innovate plug. Connecting to the LC-2 line requires a 2.5 mm to Molex patch cable.
