New Member question..Haltech and Can bus RX8
I am posting this ion behalf of a Member that needs sufficient posts to enter this section but hasn't got6 them yet.
But the Question is Very interesting.
CHRIS????can ya help this lad out?
TITLE: ECU wiring/ haltech (Posted by Slevenheaven)
Hi all, I am looking at properly getting a haltech ecu but I want to use an rx8 speedo and tacho! now the rx8 speedo tacho on the standard car uses canbus to get the info from the ecu. are you able to use the haltech canbus port to drive the rx8 speedo and tach? or will I need a converter to change the pulse input from the FD sensors to a canbus message?

I have a buddy that has a working prototype. He's hard to motivate to produce anything though because he works a lot of hours and it well compensated by his day job.
The purpose of the dual CAN-bus on the Elite is just for this purpose. One bus will interact with OE systems, while the 2nd bus is dedicated to the Haltech protocol. Only issue is developing the protocol for every platform they want to support. As of right now, the 2nd bus is a closed system on the Elite. You get what Haltech gives you. They have a couple platforms they support already and they're working on more. We've lobbied for an open front end that would allow you to build whatever protocol you wanted. Other systems have this.
What my buddy did was use a Sport ECU and build a CAN transceiver that reads the Haltech protocol and translates it into Mazda to drive the dash. There are commercially available transceivers that are expensive.

My phone is being a jerk and not letting me paste links. Google can can gateway. You'll turn up some options.
If you're smart enough to program it, you can probably build your own. You just need a CAN transceiver and a processor. My buddy used an Audrino and a transceiver chip. Well less than $50 in parts.
I question why you'd go to all the work. From a functional perspective, a digital dash would provide way more functions and be able to display a lot more information.

Right now there are only a very small amount of protocols in the ECU, but more will come.

The general consensus is that the Elite will have the capability to feed the oem CAN bus to let the signals that need to reach the rest of the vehicle's modules so the gauges will still function and no check engine light or problems arise from the lack of an OEM ECU.
