thoughts on crappy boost gauges

wholly hell...that tach is slow as piss.

for example, this digital tach is AWFUL

Wow yea that is stupid slow! It can certain go faster and still be able to read. When I was working on my dual afr gauge I tried to make it as fast as I could while still being able to discern the actual number. This is what I came up with. I don't know the exact Hz off the top of my head. Might be helpful for those that haven't seen any other digitals.

Yeah that seems like a pretty good pace. I think any more would be hard to read.

So I assume all the gauges we are going to get are "gauge pressure sensors." That being, they measure pressure in reference to something (car being off). I wonder if this is something that they calibrate at the factory or if the calibration is done at every start up?

I know the innovate LMA-3 uses a map sensor however it can be configured to be a gauge pressure sensor. It needs to be powered on for a fraction of a section before starting to calibrate to the car being off. This should give you the most accurate boost if your goal is to figure out how much you can compress the current atmosphere. I would assume this is not ideal for speed density configurations which is why they typically use a real map sensor.
