Thanks Adam and Ess, that's pretty much the answer I was looking for. For it to work like I was told sounded like some kind of magic! What you guys have said is much closer to what I thought a data bus could do. I might just put my fuel pump on a switch and use that aux for the boost control. Thanks again.

Hi adam, thanks. It's an Ej20 and I'm already on wasted spark. I'm sequential injection but I don't want to go batch fire. From memory my outputs, including the two free injector channels are Fuel pump Cel Fan Tacho I can't remember the other two but I'm sure I've got six and used them all. Nothing funky, just standard stuff. I was thinking I could run the fuel pump off a switch to free up an aux. But I'm really curious if the CAN bus run an aux device like a bcs. It mentions it in the link help file but is pretty brief and I reckon I'm misunderstanding it. Cheers. Essboo, thanks. So could I drive the tacho or fuel pump relay for example from a CAN aux? Im still confused as to how the can aux's control "dumb" components. Thanks.

Hey all. I'm running an atom on my build and have basically run out of I/O. I have been told about the CAN Aux feature, and am wanting to run a boost control solenoid off it. My understanding of a bus like this is that each device has the bus protocol and its own address so it works in turn on the bus. So I can understand how CAN devices like screens, lambda etc can run on the bus, but what I can't understand is how a "dumb" device like a bcs could run off the bus. Is it even possible or have I been told wrong? Thanks in advance.

Wait on, I updated the firmware again after updating the software and it found a later version. Now the faults are gone! The old software I had mustn't have accepted the latest firmware so only updated to one that still faulted. Thanks heaps for that!

I updated the software, it didn't seem to change anything, don't know what's going on.

OK thanks, I'll do that and see how it goes. Cheers.

I'm not sure the number but I checked and it said it was the most current and didn't need to be updated. I updated it anyway with no change. My pc link version is pretty old though, could that be an issue?

Hi, I'm wiring up my atom x into a Subaru liberty. Since powering the ecu up I have had an issue where aux 1 to 4 are in fault. I have found that they are in fault even when I have only power and ground connected to a power supply. The wiring help says that if this happens the firmware is not happy. All the aux outputs work fine, just stay red and say fault. I have them running as low side drivers to switch on relays, but it doesn't seem to matter even if they are disconnected. Pc link is showing no fault codes for this. The spare ignition channels I have used indicate fine, green active or inactive. Thanks Josh
