 When attempting to initialize the **SD VE Adjust (SDRatio)** tool, the application will check your ECU Input tab to locate the MAP sensor. ​ It will then attempt to find this sensor in your datalog. ​ Using the image above as an example, you would want to log the GM 3-bar sensor attached to the MDP input in order to use this function. When attempting to initialize the **SD VE Adjust (SDRatio)** tool, the application will check your ECU Input tab to locate the MAP sensor. ​ It will then attempt to find this sensor in your datalog. ​ Using the image above as an example, you would want to log the GM 3-bar sensor attached to the MDP input in order to use this function.

 The downside, of course, is that if you disable the air temp sensor for speed density operation inside the ECU, then you need to make sure your air temperature reading while doing your calibration drive is fairly reasonable (say between 50-90F). ​ A good working intercooler and some careful attention to your right foot will help immensely with this too. The downside, of course, is that if you disable the air temp sensor for speed density operation inside the ECU, then you need to make sure your air temperature reading while doing your calibration drive is fairly reasonable (say between 50-90F). ​ A good working intercooler and some careful attention to your right foot will help immensely with this too.

 +Also, since the ECU's Baro input is in use by the Mitsubishi MAF sensor and unavailable for aftermarket-sensor connection, you'll have to use some other ECU input for the MAP sensor (at least until you switch full-time to speed-density and can then move the MAP sensor to the Baro input, if you so choose).
