I'd appreciate input on how important it is to have an accurate battery voltage calibration. I've got a Rev-built MS3 I've calibrated to 0v at Zero ADC Count and 33.8v at Max ADC Count. That aligns the voltage the ECU sees to the voltage at the injectors under normal running conditions - basically between 13.9 and 14.9 volts. But when the engine is shut off, I'm seeing 12.6v at the injectors but the ECU is seeing 13.4v.

Is this a problem?

I tried adjusting the min and max numbers as suggested in https://www.miataturbo.net/megasquir...irdness-90312/. I get good alignment if I set min to 1.9 and max to 31.0 when the car is running but the voltage is misaligned again when the engine is off.

Many thanks in advance...
