Chevrolet Corvette Stingray C7 Forum - View Single Post - Can the PDR be upgraded to capture additional data channels?

Comparing a '17 ZL1 PDR file to a '18 ZL1 1LE PDR file, the newer file contains additional data channels.

Intake Air Temperature
Outside Air Temperature
Suspension Displacement Left Front
Suspension Displacement Left Rear
Suspension Displacement Right Front
Suspension Displacement Right Rear
Wheelspeed Left Driven
Wheelspeed Left Non-Driven
Wheelspeed Right Driven
Wheelspeed Right Non-Driven
Yaw Rate
...

These additions are great, but the post-compression Intake Air Temperature (IAT2?) channel is notably missing. I realize channels compete for bandwidth and adding channels may impact the frequency at which the data can be captured, but this seems like a worthwhile channel for the forced induction models. Why is this channel not included?

Can the PDR software be upgraded to capture subsequently introduced data channels? If not, can the recorder modules be easily swapped for newer models?

Are there any new data channels introduced with the PDRs on the '19 model year?
