Hey guys,
Will try to check in on this forum from time to time to answer questions as they come up! We're all excited about the new G70 platform.
In terms of the JB4 what it offers that no other tuning system currently offers for the platform is CANbus integration. Meaning the JB4 is able to read and see every piece of information the ECU has. That gives us the ability to add in some unique features. Just a few off the top of my head:
1) User adjustable boost by gear to lower boost in lower gears for increased traction.
2) The tuning is able to take in and utilize much more information for its tuning integration including pedal position, engine temperature, throttle position, performance mode, gear, intake temperature, etc, etc.
3) More advanced safety systems with the JB4 monitoring AFR, fuel trims, knock, full time in the background, and reverting to a safety map if something looks out of spec for the map.
4) Full datalogging and diagnostics to your phone. See video below.
5) The JB4 has a lot of extra inputs/outputs allowing us to add things like direct fuel control, water meth integration, and more, as we further explore higher power levels with the platform.
In terms of the warranty stuff we always advise customers that if you break something by running it at higher than factory power levels YOU should pay for it. But that said with the JB4 in place we expect a very high level of reliability with the platform, and the JB4 system itself is diagnostically invisible and installs/removes in minutes. Since it has CANbus it's able to clear all codes and freeze frame data out of the ECU when needed.
