Anyone have any thoughts on this? At least in my region in the US, MyLaps is the timing system used for the majority, if not all, of events. I wonder what Garmin will do with this.
Maybe come up with a data logger that’s also a transponder, although that would be difficult based on where transponders have to be mounted(side pod or back of seat), and where you normally mount your data logger(steering wheel).
I just want an app that doesn’t suck. SpeedHive was actually pretty decent, but Race Monitor is an awful moneygrab. I don’t understand why I can’t use My Laps to look up data that was collected with their own products, and the app is glitchy half the time.
What’s wrong with RaceMonitor? Always works for me, easy to navigate.
Beats the hell out of Alpha.
Alpha is growing on me. At least most tracks around here are gravitating to it. I don’t care what app we use as long as we all use the same one!
This might be a noob question, but why must transponders be mounted the way they are (Side pod, back of seat)? I understand why it shouldn’t be on the steering wheel and moving, but why not another static location?
location is not important as such, what’s important is to be on the same part of the kart as other competitors.
An advantage can be gained by not having the transponder on the same location as other drivers. If i have my transponder inside the nosecone and someone else at the back of his seat and we cross the finish line with you being slightly ahead of me, i will end up wining the race as my transponder will cross the line before yours, if it makes sense.
Well, that doesn’t really make sense to me.
The transponder activates when it crosses the line, and the time between when you cross the line, is what determines your lap time. I’m sure on the back end of speed hive, it looks at your laptime, and the time of day you crossed the start/finish (among other things) to determine what position you are actually in.
If I mounted my transponder on my rear bumper, my lap will “start later” as the majority of my kart will be across the line when the lap actually starts. But as a result, my lap will also “end later” because the transponder is at the back, nullifying the later lap time start. You will be running the same time regardless of where it is mounted. Maybe I am thinking about this wrong though?
The only way to gain a significant advantage would be to take your transponder off, and throw it across the line ahead of you 
.
The issue is that you will have a different physical result compared to what the system will be showing, and how do you tell someone who physically crossed the line first that he did not win the race?
To avoid any confusion or protests drivers need to have their transponder in the same area of the kart.
That is indeed true.
I am surprised that the ruleset for my series seems somewhat loose for where you can mount the transponder. And on the grid, I have seen a lot of variation among drivers on where they mount the transponder.
" 19.2 Transponders may be mounted no closer to the front of a kart than 12 inches back to the leading edge, from the center of the kingpin. It is recommended to mount the transponder at the back of the seat. "
Skusa is much more strict, which makes sense: “Must be mounted in the correct location in every official on-track session, including timed practice. Transponder shall be mounted per CIK positioning: on back of seat at a height of 25cm +/- 5cm. Incorrect mounting may result in a penalty.”
If you and I cross the line dead-even, and my transponder is mounted on my front bumper and yours on your back bumper, I win the race. Even though our vehicles were both side-by-side at the line.
It doesn’t matter for lap times for the reasons you said, but for racing it matters.
Indeed it does. Much more important in a race, than in quali or practice.
That’s why I keep mine in my pocket so I can chuck it down the straight on the last lap. 
In RoadRaces we zip-tie them to the front bumper, unless a series hard spec’s a location.
I would personally prefer that versus having to reach around the back of the seat, around the exhaust, and drilling holes in the seat to mount a transponder.
I’m sure there is a reason why most sprint series do the back of the seat. I just don’t know what that is.
The problem with back of the seat, is that it’s not an absolute location amongst drivers. My 6’5" driver’s seat is much further back then our 5"6" teammate. If they cross the finish line at the same identical time, the taller driver loses.
Huh? It’s like $5/yr….
Does what’s it’s supposed to and no more.
Last weeks finish at a CKNA race, where the transponder is mounted to the back of the seat.
.002 difference in time.
True point. I think the front chrome hoops are a set length unless you run a porch extension which I think allows you to run the front bumper further away which would give you a potential edge.
I thought I had read some rules that say something like on the sidepod 12" behind the front axle centerline?
