what is the minimum distance apart that the EFI should be mounted from the MSD? Not looking to put them on the same panel but looking to declutter the wiring some and move them a little closer together. Is there any sort of RFI interference problem?
I've seen them mounted side by side with no issues. Most important thing is to run the main wires back to the battery, don't tie them together and run a single wire back. Adds more weight this way, but I have never had any RFI/EMI issues with two sets of wires going back.
