Has anyone wired and used the 2-Step function in the Holley Sniper EFI? I set mine to Input #2 wire on the harness, and enabled it through the touchscreen, and set the RPM to 3400. Tried wiring it through a switch to ground and nothing. Then disconnected the switch and touched the Input wire to ground and nothing. Ideas?

Also, what is the retard launch option and what are the advantages of that? First build for me and so far everything is running great. Will be installing the dual sync distributor this weekend. Thanks in advance!
