Analog input is scale is wrong

[cnjboards]

I upgraded my existing application from V3.0 to V3.1. It is an engine monitor application.

I am using a built in analog input (36) to scale a pressure reading.

The code snippet is below:
(note: OIL_PRESSURE=36)

// Oil Pressure Sender Config //
// transducer has .5V - 4.5V for 0-100psi (689476 Pa).
// Analog input is 3.3V raw with a resister divider of 7.5K and 11K.
// analog input returns 0raw=0V and 4095raw=3.3V @ the pin.
// thru resister divider, .5V xducer ~= .2V at chip = .24095/3.3 ~= 248 (125 actual)
// 4.5V xducer ~= 1.82V at chip = 1.824095/3.3 ~= 2258
const char *kOilPressureADCConfigPath = "/propulsion/Engine Oil Pressure/ADC/scale";
const char *kOilPressureLinearConfigPath = "/propulsion/oil pressure/calibrate";
const char *kOilPressureSKPath = "/propulsion/oil pressure/sk_path";
const float OilPmultiplier = 228;
const float OilPoffset = -82080;

// Oil Pressure ESP32 Analog Input
auto analog_input = new AnalogInput(OIL_PRESSURE, 500, kOilPressureADCConfigPath, 4096.0);

auto analog_input_linear = new Linear(OilPmultiplier, OilPoffset, kOilPressureLinearConfigPath);
ConfigItem(analog_input_linear)
->set_title("Engine Oil Pressure Scale");

analog_input
// scale using linear transform
->connect_to(analog_input_linear)
// send to SK, value is in Pa
->connect_to(new SKOutputFloat("/propulsion/oil pressure", kOilPressureSKPath,
new SKMetadata("Kpa", // Define output units
"Oil Pressure Kpa"))) // Value description

  // for N2K use, value is in Pa
  ->connect_to(
    new LambdaConsumer<float>([](float engOilPresValue) {
      OilPres = engOilPresValue;
      // if negative then make zero
      if (OilPres <= 0.0) OilPres = 0; // for some reason n2k does not like negative oil pressure??
    }));

Below is the verbose debug output from serial for this sensor:
signalk_delta_queue.cpp: delta: {"updates":[{"source":{"label":"EM V3 Lite"},"values":[{"path":"/sensors/digital in2","value":true},{"path":"/propulsion/engine RPM","value":1773.222},{"path":"/propulsion/oil pressure","value":1.960344e8}]}]}

Notice the output value for oil pressure is now 1.960344e8 which very wrong.
Everything else is working as expected.

This is what the debug log looks like in V3.0, no code change, same signal inputs.
signalk_delta_queue.cpp: delta: {"updates":[{"source":{"label":"EM V3 Lite"},"values":[{"path":"/sensors/digital in2","value":true},{"path":"/propulsion/engine RPM","value":1770.319},{"path":"/propulsion/oil pressure","value":181672.6}]}]}
