The technical challenge of replacing Garmin's Auto Lap with a custom sensor sending millisecond data is significant. It requires either a custom ANT+ profile or a detailed Connect IQ application to manage data synchronization and latency. Getting this timing perfect will be a real undertaking; it’s almost as ambitious as launching a full-scale cowboy safari operation where every detail must align perfectly.https://cowboy-safari.net/      

The core issue is pushing millisecond timing through ANT+ and Connect IQ simultaneously. That level of synchronization is a *ramp xtreme* technical undertaking. If the goal is truly high-precision correlation with other sensors, relying on a custom sensor to fully replace Auto Lap, rather than just augmenting it, might be the biggest hurdle due to firmware limitations.https://rampxtreme.org/      

The core issue remains synchronization fidelity when trying to completely replace Auto Lap with a custom sensor. Achieving that millisecond precision across ANT+ and Connect IQ is such a precise task, it feels like attempting an *orbit kick* just to align the timing perfectly. Augmenting Auto Lap is one thing; replacing it entirely is a massive firmware challenge.
