This may have an obvious answer, but how do these systems "know" what time may be left on the table? Specifically, there seems to be the "unknown" variable (based on your tires, suspension setup, etc) of whether the car is going to hold if I carry X amount more speed through this or that corner by braking later or doing whatever the coaching tells me to do. Do these packages somehow use fancy algorithms of being able to "predict" what your car is capable of by analyzing other corners (max G established in some other corner, for example) or some other technique (or input parameters)?
Just curious |

Thanks.... it is interesting to consider then exactly how useful these things are. Not saying they're not, but by that logic you basically have to set a faster time for the thing to be able to know that you can set a faster time (!?). I understand the concept of putting together an ideal best lap from individual best sectors, so I guess that's where the value is. But at the end of the day, if you want to push your times on any one sector, it sounds like the fundamental limitations of the method can't really help you (which is understandable). Unless I'm missing something.
Just trying to get a sense of how useful this would be. |

It worked better at Mantorp than Sviestad. Maybe it had a hard time understanding some corners there? I don't know.
Garmin Catalyst - Trackday #2 Mantorp (FULL unedited session 1) Filming the Catalyst using Racechrono for reference. You can see what the Catalyst shows on it's screen, what the Catalyst says and also see some extra data recorded with Racechrono for reference/comparison to the Catalyst and the driving. Three warmup laps. Really cool cars on the track! Formula open wheelers, GT40, Ariel and some Porsche GT cars. I start pushing from lap 4. Still some time on the table when I finish the session to what I can do normally. More in session 2! You be the judge, do you think the Catalyst is giving me good coaching tips this trackday? |

Awesome, it does seem like it generally helps. I'm sure with less traffic you would have matched your PB. I did notice the weird lines it suggest at times, so that may be a bit confusing to others.

Personally, I don’t think it is relevant, and I think folks should save up and get AiM with sensors plus smartycam, get someone faster to do hot lap to put data and the aim, get coaching on how to use aim. Great idea though, and thank you so much for sharing and beta testing for everyone |

When Covid hit it seems all IR sensor manufacturers focused on sensors for common handheld thermometers and other sensor types were put on hold. So they became out of stock in many places and the ones available went up in price. But it is a couple of months since I checked last, so I don't know availability right now.

If you then record all of these samples and store the maximum values of that total acceleration then you now have a series of maximum acceleration vectors that you know your car is capable of. When you start sliding those acceleration sums naturally drop. That's why this system, apex pro, and many others that have focuses on letting you know how much available grip you have take 2-3 laps to warm your tires up and figure out how much grip you have available. Anyone who has more knowledge on the subject feel free to correct me if anything I said was wrong, I'm in the process of figuring this out myself. It seems to make sense to me and this photo from the AIM manuals helped me understand that G-G diagram. The rest of the calculations from a timing segment point of view are based on what your bests are -- the combination of G-G diagram, line, and GPS come together to form their secret sauce which tells you the timing you could improve on. |

Yeah, my experience is it uses your best times to suggest quicker driving lines.

Found a few thermopile arrays that might be a suitable alternate, albeit considerably lower resolution(8x8 vs 16x2). But might be workable for now, until the higher resolution sensors are restocked. Going to fiddle with this a bit, seems like a fun project.

Pretty cool, thanks for sharing! What does it mean when it says "keep pushing." It said it during the final turn. Does it mean "get on the gas"?
