At FTY, we’re working through Haltech’s CAN Bus information. The CAN ID information is available out there, but it’s pretty hard to find So, we thought we’d post a handy reference, just in case you end up in a situation where you’re trying to find CAN information to use with your own dash, data logger, gauge, whatever.
Haltech’s CAN protocol uses 11-bit identifiers and runs at 1Mb/second. Data on the bus is encoded as big-endian, and most of the values are in metric. So, kph, kPa, kelvin, Liters, stuff like that. Here are the hexadecimal ID’s for information on the bus.
These IDs work on the Haltech Sport series ECUs, but may also work on their other ECUs, too.
