Thoughts on the FAST Ez-EFI system??

How does an average guy monitor each cylinder individually to take advantage of this feature? I can see that on an engine dyno with headers that have pyro's or a/f bungs at each pipe. I'm thinking most of the guys never get their engines on an engine dyno and do their tuning on a chassis dyno or on the street and wouldn't have that type of exhaust to be able to individually monitor a cylinder. Would an infrared temp gun on the tubes give enough info? I do remember that feature and played with it a little, but I didn't have a real good way to monitor things other than a temp gun. This was a blown small block, not an IR setup but we were chasing a problem.

The Holley Dominator system has individual fuel trim, you will need to tune on a dyno with 8 o2's to perfectly set them, or use 8 EGT's, we use an IR thermometer to see if any cylinders are leaner or richer, and adjust there. IR systems are tricky and usually not worth the hassle, we did 2 over the last few years, although they look great!
