I messed up on the gauge


The gauge maxes out at 10psi and the car runs at 2-3 bar (30-45psi)
Gauge and sender were expensive and fitted so I would like to use them

Josh reckons that we can fit a resistor in-line to the gauge input

I would like to alter the gauge reading by a factor of 10 so that 1 psi on gauge is in fact 10psi.
Can any electrical bright sparks confirm if this will work and if yes the size of the resistor required (or how to calculate it).
