How exactly is the piggyback using any of this CANbus information? Integration would imply that it is intercepting the CANbus information, and using the unit to somehow modify or implement the data traffic. It's been mentioned numerous times in regard to the Giulia, but I don't see anyone using it, nor putting it to actual use in anyway in regards to tuning. It's simply there for the user to look at.I can confirm the JB4 does have RPM access. Where I feel it’s a better solution is that it has full canbus integration which gives it much more data to use versus a simple piggyback.
RPM access? Through CANbus traffic, and not directly from the sensor. Again, paired with my question above, how is the unit actually using this RPM data traffic?
More so, the tune on the piggyback was developed prior to their being RPM access through the CANbus, and it has no other source for RPM that I know of. So how can the calibration on the unit be made based on different RPM/load/throttle axis points if it didn't have this information from the beginning?
These are all honest questions, I'm not trying to take a dig at the system.
