The current crop of EFI systems on the market are light years ahead of where we were 10 years ago. With that said, there are lots of times when someone purchases an EFI system for their ride that works great and does everything they need, until a couple years goes by and they get fancier and fancier with their combination and run out of useable Inputs and Outputs. This happens all the time, and while there are some workarounds, they usually involve dumbing down some component you really would like more control over.

Behold the Holley EFI CAN Input/Output Module. This little box is a very powerful tool that can give you all the inputs and outputs your little heart desires. Have an ECU with all the inputs and outputs you every thought could be used and still ran out? It works on those too. Check it out.
