MAP Sensors

[hstaton]

The EFII ignition I am using utilizes the identical MAP sensors that the Skyview uses. The manufacturer of the EFII says that there is no problem with ganging the sensors together for the two ignitions. Is there an issue with ganging the MAP sensor for the Skyview with them?

It will work while everything is working right, but in failure cases it's sub-optimal.

The issue is redundancy. They will all share one power source and have one output ganged together. Thus a failure of either ignition or SkyView can cause the MAP to be wrong, which will cause your engine timing to be wrong.
