Cleanest Boost/AFR/Voltage gauge EVARRRR!!
Great Gauge, I have had mine for about 8 months for just boost. Now I have tied my AFR into it but the afr numbers seems to be slightly off.
I'm using a Zeitronix zt-3.
My afr seems to be off about .4 compaired to logging/viewing real time from the zt-3 it self.
Directly from zeitronix zt-3 to laptop at idle is 14.7 on stock tune.
The Zeitronix default for the linear output is 0 Volts = 9.6 AFR, 5.0 volts = 19.6 AFR to the VBG1 i get 14.3
If I change the values to 0 Volts = 10 AFR, 5.0 volts = 20 AFR per VGB1 instructions its off even more and shows 14
I'm guessing I need to move the scale in the opposite direction, just wondering if others using a Zt-2 or Zt-3 had to as well?
