Click "Next" to install FlashApp and all drivers

Next, we will install the DATAQ analog DAQ (DI-1100) Instrument Drivers. The optional data acquisition (DAQ) box allows you to capture up to four additional 0-5V analog signals in data logs. DAQ is compatible with analog signals for boost pressure, oil pressure, ethanol content, linear temperature sensors, switched inputs, etc. The DAQ does not work well with sensors requiring low latency and high accuracy such as wideband controllers or MAF sensors. If this option was not purchased, then the installation of this second driver can be skipped. 

If installing the DAQ drivers, accept the License Agreement and click "Next"

Congratulations, you have successfully installed Severn FlashApp! Your next step is to license the vehicle. You will need the Severn Remote Flash K+DCAN cable to proceed.
