I assume Holley R&D guys read the forum?
I'm starting to run out of I/O pins, but I notice there are many more inputs/outputs configurable in the software than there are physical pins, which got me thinking... would it be possible to invent a stand-alone I/O Interface box for Holley EFI systems?
What I mean is, a separate box/module that has:
This could be used to add 52 input/output pins to any ECU, in fact, depending on how much data the CAN Bus can support, you could add as many of these modules as you want.
I can't see why it wouldn't be compatible with existing hardware (although I'm sure it would require some software support with a firmware update)?
The other advantage is much less wiring, we could mount one of these modules in the under-hood fuse panel, one behind the instrument panel, one in a trunk-mounted fuse panel (etc.), then all we'd need to do is run a twisted pair CAN Bus connection between each box and the ECU. All the associated wiring would then be done locally instead of running great bundles of wires throughout the car. Thoughts?

What I mean is, a separate box/module that has:
- J3 & J4 connectors on it (so it uses the same 558-403 & 558-404 accessory harnesses); and
- Power and Ground inputs (with a couple of rectifiers inside for filtered +5v / +12v / Low references); and
- A CAN connection back to the ECU.
