TunerView Android App


The much anticipated launch of our TunerView Andrdoid app is just around the corner. We are now taking early adopters who want to give us initial feedback on the app. All you'll need to add to your existing NepTune RTP is a Bluetooth module. We'll allow the early adopters into a private Google Community and you'll be able to purchase a copy of the app. Please email us if you're interested!

Demon II Released


The Demon II is a hardware refresh that is replacing the original Demon for all USDM/EDM large box ECU NepTune RTP packages.
-This sleeker unit is more stable when installed.
-No longer requires a battery for data retention.
-Comes with the TunerView Data Header and Analog Input header pre-installed.
-Features a ferrite bead onboard to help reduce interference.
-Two USB ports so you can decide whether to cut the ECU case or not.
*JDM ECUs will still need to use the original Demon unit for fitment.
