Are all the NSP functions available in the R5 also available in the R3?
Yes. The R3 shares all the NSP functions, including the Oscilloscope and all the Advanced Tuning Options like Torque Management, Nitrous Control, Race Timer, Flat Shift and Closed Loop Boost Control with the R5.

Does the R3 have Wi-Fi?
Yes. The R3 features an in-built Wi-Fi module for wireless communication and will ship with a Wi-Fi antenna.

Can I use the R3 on V8 engines?
Absolutely. The R3 will support 2, 4, 6 and 8 cylinder engines. However, if you are planning to run more than one injector per cylinder on your V8 you’ll need to get the R5.
