At MoviChip we use the sensor output as a percentage or in volts. We do not use pressure units for MAP sensors or flow volume for MAF sensors etc
We do not supply sensors and we want to offer you the ability to use any 5 volt sensor you wish. By using percentages and voltage you can use any sensor you wish with MoviChip products
Once you know the sensor specs you can calculate the percentage/voltage reading you need.
At some point in the future we may offer a calibration feature to our products but at the moment, the products we have are not designed to display sensor readings.
Plus it adds an extra level of complexity which we do not believe is justified with our current product range.
In short, we think % and V are better
