Weird noise after 4 speed install

Before adjusting the idle timing in the FiTech software I would throw a light on it and see what your distributor is installed at. I don't believe the FiTech allows your idle timing to be set lower than what the dizzy is stabbed in at. ( I could be wrong on that one though) Mine is stabbed in at 18 degrees, and I run 20 degrees at idle and 34 pretty much anywhere else, it works with my setup.

That is the first thing I checked after cam break in. I set the unit to "locked" and 30 degrees on the handheld. Then double checked the timing on the balancer at 2K and 4K to be sure they were the same (on the balancer and the handheld) and they were. I then unlocked the timing on the handheld, which reverted back to 18 deg idle adv (what is set in the handheld) and that is what the balancer showed also.

I do know that you can set your "start" timing separate from your idle timing. I have mine both set to the same.
