Davidv Posted May 16, 2019 Report Share Posted May 16, 2019 The scale on the cal tables can only be volts or resistance... What do I do, for a DI when a cal table has been set? Quote Link to comment Share on other sites More sharing options...
cj Posted May 16, 2019 Report Share Posted May 16, 2019 DI's dont have calibrations, they are just on/off/frequency. If you mean analog inputs, what else would your input value be other than ohms (resistance) or volts? do you have a sensor that output varying mA? you would have to either replace the sensor or set up a shunt resistor to convert it to a voltage input. Your output value (ie the pressure/temp/angle you are measuring with the sensor) can be pretty much anything. Quote Link to comment Share on other sites More sharing options...

Your output value (ie the pressure/temp/angle you are measuring with the sensor) can be pretty much anything. An example: Going through the options it looks like MAF is the only one with this quirk. I want to run one of the more modern MAFs which has a humidity sensor. The fact that Humidity outputs as a frequency isnt a problem at all, as theres no input for humidity so its frequency will just be a load axis on a trim table anyway. But the mass air flow signal is digital too, and mass air flow being mass air flow is pretty critical for the rest of the modelled fuel stuff to work nicely. If a frequency based maf doesnt work, not the end of the world to be honest. Quote Link to comment Share on other sites More sharing options...
Simon Posted May 16, 2019 Report Share Posted May 16, 2019 You can't is the short answer. Im not actually sure that MAF should even be an option currently in the Di channels. Davidv 1 Quote Link to comment Share on other sites More sharing options...
