low vs high impedence injectors
Can MS run both without needing to wire in resistors? AKA what would i need to do to run low impedance injectors with MS

I'm hoping all that is needed is the additional ground wires that aren't pinned out on the board. I had my new PNP made like that from DIY and an MS parallel made by cjernigan. I will let you know in a week hopefully. Got low impedance 440's waiting to be installed.
