I'm disappointed to say that my Autometer Ultralights aren't any better than the luck you're having with SW.
My water temp gauge fluctuates from 160 - 240 and back within 1 second.
My fuel pressure gauges is 5psi out.
My
oil pressure is 12psi out.
My fuel level fluctuates wildly (probably sender location - my fault)
My boost pressure is out 2 psi.
Tach works a treat !
Speedo hasn't been hooked up yet
It's so bad that I take no notice of the gauges anymore. I have an aftermarket engine management system that I've programmed to activate a warning light if any engine parameters go out of my preset ranges.
Pretty sad when I have a dash full of gauges that are useless....
