Haltech CAN Module Update

[C. Ludwig]

We got a set of pre-release CAN expansion modules a couple days ago for evaluation. We received the I/O-12 and TC-2 modules as well as the CAN Hub module.

The I/O-12 is a 12 channel module, as the name suggests. It features 4 analog inputs, 4 digital inputs, and 4 digital pulsed outputs. The analog inputs would be generally be used with temp and pressure sensors, though other functions are possible. The digital inputs can be used for pulsed wheel speed sensors or as direct acting function controls. The digital outputs can control pulse-width functions such as idle control or boost control, or simple on-off functions such as cooling fans and fluid pumps. Other options would be available for these inputs and outputs, I've only given brief examples. The I/O-12 includes an 8ft long flying lead harness.




The TC-2 is a 2 channel thermocouple module. The TC-2 includes high quality, open element, K-type thermocouples. The open element is key for a fast response sensor. We expect a 4 channel version of this module as well.

The CAN Hub allows multiple CAN modules to interface with the ECU. The network will allow a single CAN device to interface directly with the ECU. So, you would be able to run the I/O or TC box by themselves without the need for additional devices. If you want to run multiple input modules you will need the CAN Hub. The CAN Hub would then connect directly to the ECU and up to six devices can be connected to the hub.

Pricing is not yet available.

We will be installing the I/O-12 on our project turbo Miata and using it to run the idle speed control and our water injection setup. The Miata uses the Sprint 500 ECU and we easily used up the two programmable outputs and need more. The I/O-12 is the answer we're looking for. We'll also be using the analog inputs to monitor intake temps and pressures, and input from out Phormula knock monitor as we continue to develop the package.
