@mck1117 https://github.com/mck1117/wideband/pull/314 . But needs more testing.

[two_heat_up.zip](https://github.com/mck1117/wideband/files/10739707/two_heat_up.zip) @mck1117 started from ~6V then rise to 12.5V, wait until heated.

I believe this is because of long wires to power supply and supply capable of 3A only.

@mck1117 me, Andrey and one more beta-tester have f1_dual (rev0) boards. So I'd like to have this code in master. On other hand I can supply modified FW to few...

Also. In case of `Preheat` state target `heaterVoltage` is 2V. For dual boards it is possible that WBO is powered while supply voltage is not applied to sensors (supplied through...

See comments at https://github.com/mck1117/wideband/pull/140

Or maybe this is caused by rapidly increased heater PWM? Unlikely. Issue can also be solve by using hysteresis for `underheatESR` thresholds.  [lsu42_heating.zip](https://github.com/mck1117/wideband/files/11037524/lsu42_heating.zip)

I'll do some testing later.

Pump control enabled only after sensor reaches `targetESR`  [lsu42_heating_mod.zip](https://github.com/mck1117/wideband/files/11044969/lsu42_heating_mod.zip)

Looks like Nernst voltage is too low and AC component is clamped. This gives us lower ESR than actually it is. When we start feeding pump with some current Nernst...
