Different transmission speedo problems

[Gdbrwd]

Hi I’m running a plug in for the v7 sti and not using the factory transmission. Is there anyway I can run the factory speedo off the abs tone wheels or a gps module? Current gear box has no speedo drive and I would like the cruise control and odometer to work. 
I have been using an app on the phone as my speedo to get by. 
appreciate the help  thanks

Yes you could connect a GPS speedo sensor to a DI (such as the Haltech HT-011310), then use the "Speedo output" function to send a calibrated signal to the speedo.
