I noticed that in all of my logs that I never receive any messages with id 0x421 (what's supposed to contain this data). Looking at the spreadsheet, I see that this message also transmits the S-Mode status. I remember a post I read a while back about adding rev matching to a base model, and two of the things needed are a gear position sensor and a new ECU. Given that I don't have the proper ECU (or even the actual sensor!), this has to be the reason that this message isn't on the bus. Just a heads-up to anyone with a base model trying to sniff out the CAN bus.
Yup, the base model does not have the gear position sensor. You could always do what my motorbike does and compute the ratio between the RPM and rear wheel speeds to look up the gear. Only works when moving and clutch engaged though.
