fuel gauge calibration

[jjg]

Hello All

Does anyone have the calibration values for the Fuel gauge values, ie what are the PWM values for the levels fronm the sender unit ? from high to low level , I seem to have lost the values as the gauge seems to puls width .

The car is a v8 vy2 gen 3 (commodore)

Thanks

The fuel Guage sender is a simple variable resistor in VY its hard wired to the dash

Yes that may so , but the software require calibration values in table , what are these values supposed to be ?

[TTVN]

set to zero

what is the exact issue with the guage?
the only way it can loose the calibration is through a bad programming error

one set of values i have is
fuel resistance 60 65 100 120 140 160 175 195 210 235
fuel litres X 2 150 132 122 112 102 96 86 74 50 20
from a sedan

what are you using to program it?

HP tuners and yes the answer is to set the PWM gauge output table to 0

THanks you all

ahh that explains a lot, the dash does not use PWM so set it to Zero
