Swapped out a 20 year old controller board last Tuesday and the ride quality is night and day
I replaced an old MCE controller board in a 10 stop passenger elevator in a condo building near downtown last week. The old board had been having intermittent door zone faults for months and the ride was jerky as heck especially on the top few floors. Put in a new GAL board and adjusted the door timing parameters from the default settings. The start is smooth now and the leveling is within an eighth of an inch every time. The building super even came up to me and said 'it feels like a new elevator' which felt pretty good. Has anyone else seen that kind of difference just from swapping the brain of the car? What controller did you switch from and to?

Swapping out an old GAL board like you did is almost always the fix for those jerky rides and door zone faults. Had a similar situation a few years back with a Motion 2000 controller that was causing all kinds of overshoot, switched it for a Smartrise and the difference was honestly unreal. Sounds like you got it dialed in perfect with those timing tweaks too.

You ever seen an old GAL board cause an elevator to stop two floors apart, right at the gap, and then just sit there humming? Buddy of mine had that exact problem with a 1980s Reliance setup, spent two weeks chasing wiring until he ditched the board and it ran smooth as butter. @jessec39, you're dead on about that swap being the key, those old boards just degrade over time and nothing else fixes it.

I've seen that humming gap thing before, swapping the board always works.
