Dash2 Fuel Level Clip at 0 and 100?

Postby JArmstrong » Fri Sep 14, 2018 11:51 am

Hi,

I have an older Dash2 that I just installed in a Honda CRX. I hooked up fuel level to analog 1 on the Dash through a pullup resistor.

I filled the tank from empty in 2L increments and recorded voltage on the Live monitor. I plotted the data and generated a 3rd order function in excel to enter in the Dash2 setup software.

Since the function is a third order, and the fuel level voltage seems to float around, I get a reading of 110% at full. I can't seem to figure out a way to clip the value to 100 in the dash software. It is easy enough to put a max and min on the Analog 17 value (Dash Analog 1) in the Live monitor - why is this feature not available in the dash setup software? Or is it?

Conversely, it would also be nice to clip the fuel level at 0%, as 0% on the fuel curve is where the vehicle experiences fuel starve on the track. So the dash will now read negative values instead of clipping at 0.

Hello,

Please send your DASH2 configuration file & voltage versus fuel level readings to my email: daniel (at) race - technology (dot) com for inspection.
