SimJet offers the IRDT (Infra Red Data Terminal).

This device allows the user to view the start sequence, operating parameters, battery voltage, pump voltage, RPM, total time, etc. in real time via a hand-held wireless data terminal. You can also set the thrust levels (low/medium/high) and the plug voltage with the same data terminal... However, the terminal has to be plugged into the ECU's wiring harness with the included cable to affect any changes.

I believe all new engines are shipped with the IRDT as part of the package. Older engine owners can have the required firmware uploaded to their ECU and purchase the IRDT hardware from SimJet or their SimJet Dealer.

You can see it at Great Northern Models website:

Hope this helps!
