Sport and Sprint ECUs

The Racepak dash can be used with any of the other Haltech CAN accessories. You will simply need the hub module when connecting more than one CAN product. So if you have a dash now and you want to add an I/O box you would need to purchase the I/O box and the hub module. The hub then connects to the ECU and the dash and I/O box connect to the hub.

Got a chance to play with the I/O box today and it works as advertised. One of the nicest things about the I/O box is that it adds some features to the Sprint ECUs that aren't available in it's standard configuration. Add the I/O box and closed loop idle control and NOS outputs are available as well as fuel and spark trim inputs.

Also, up to two six position hubs can be used with one ECU. That allows a total number of expansion devices to be nine (12 slots total, one use for the ECU and two used to connect the two hubs). Right now the only device options are the I/O12 and TC2/TC4. Expect other offerings in the future such as internal logging memory expansion, GPS receiver, etc.
