There is no flipper lag. When you hit the button, it energizes the coil. If your flippers are really slow or weak then you need to rebuild them - and do it properly. Did you replace the flipper bushings that go in between the playfield and tgd flipper bracket? Did you use the white flipper gap tool that comes with the Williams goodie bags? Just having "new parts" does not indicate your flippers are rebuilt correctly.

Also check the EOS switch contacts.

It doesn't matter on his games. ( TZ and TAF )

Fliptronics, EOS points are open. And the game ignores them if not working.

Unlike what you might think, the Fliptronics board performs no actual signal processing like the CPU. Basically all it is is a set of transistors that engage when the flipper button is pressed. There might be a controlling transistor on the CPU board to control when the flipper buttons communicate with the Fliptronics board, and the CPU can also send signals to that board to flip the flippers on its own.

Granted, there is a few microseconds of lag, but normal human sight/process/react lag is about 1/2 second, so the extra few milliseconds of "lag" is hardly a factor when the flippers are operating properly.

Even system 11 flippers have a very small lag...while the electrons flow between the flipper cabinet switch and ground...186,000 miles/second divided by about 5 feet of wire...

I understand you..I like the feel of leaf switch flippers vs Fliptronics as well personally. I feel leaf are snapper and easier to tap/control. My TZ feels sluggish as well due to the wider and larger super pin body.. Mostly mental, as my slot scoop shows..it's not lack of flipper power!

You can check how much you need to press in the button before the switch engages and do some tweaking to adjust that if needed. Have you looked at that?

Same as EM's with four flippers and two sets of points on each side. Push in slightly and one fires, further and the other fires.

Manufacturers probably wanted the same pattern for players wishing to only use lower flipper.

Hate to resurrect a dead thread here, but would replacing the opto interrupters help with this problem?
