Holley Sniper Timing Control - Worth it on ZZ502?

[davepl]

I have a ZZ502 that I am putting a Holley Sniper EFI unit on. I'm wondering if the car would actually benefit much from ECM timing control. Right now I'm not planning on it, and will just continue with the mechanical distributor.

The cam in the ZZ502 is 224/234. In theory, the computer should be able to "smooth" the idle out by advancing/retarding individual spark pulses.

What I don't know is how well it does that and whether it's worth it on a motor with this cam.

Would I like it to idle smoother? Sure, I suppose I would. But I have no idea what kind of difference if any, it would make. Has anyone experimented with enabling/disabling computer control of the timing to see what difference it makes?
