I planning on participating in a few TT in the upcoming year. I have an AMB Transponder from a kart, but I'd like to get an inexpensive lap timer (nothing fancy with GPS and all that) just something to look down at a see what my lap time is and is I'm off or up on my previous lap and best lap of the session. Any recommendations and the appx. cost?

HotLaps, they are about $200 and the transmitting beacon is set up by the club so you don't have to worry about it. You may be able to get a used one for less.

Jad, ever hear any chair (AX, DE or TT) consider placement of a second transmitter on the course?

It might be interesting to compare first and second sector times with other drivers looking for more information on where they might be gaining or losing time.

I posted to a 914 forum that I belong to and got a good used one for 100$ including shipping.

I looked at the Hot Laps system and it looks fairly simple. Has anyone ever used the karting system? It measures the head temperature and revs which would not be needed for TT, but it does measure lap times and hold then in memory. I'm wondering if the beacon system used for that is the same and all I'd have to be is take it off the kart and put it in my car when doing TT.

Don,

For that you need to move up to a data aquisition system like the G2X or Aim. They give you all the info you could reasonably want. Tricking the hot lap with multiple beacons makes finding your lap time much more difficult and ever requires math Though technically that is what we do for AX, but sector 1 is the ax track, sector 2 is the pits, that is why there is a start and finish beacon. Not sure if the club has 3 beacons even if they wanted to try real sectors.

I think the G2X system is really nice for about the cost of a nice set of tires, expecially in 2 driver cars. TONS of information to make you both much faster. Let me know if you want more details.

Thanks, Jad. I guess my posting wasn't clear. As I think about it, I was suggesting a 3rd or even 4th beacon for sector timing on the coarses.

Without much driver interest, it doesn't sound like it is worth the club spending a lot of money on something. But, the Hot Lop transmitters are inexpensive and might warrant the experiment, if there was adequate interest.

All this is, of course, predicated on a sizable number of Hot Lap units in use today. Perhaps the current use at any one event is a relatively low number?

The bottom line for me - Grosekemper got me by a half second Saturday. The guy is amazing. It would have been fun, and quite helpful, to know where I was losing that half second. I was "guessing" I could have been quicker on the second half, but "knowing" would have been much better.

Just wanted to note that I was able to buy a complete outfit off of http://www.rennlist.com/ads yesterday for $125.

Jad's point is that Hot Lap timers can't do sectors in addition to laps, they only do laps, period. So if you put four beacons out, four laps will be recorded on the Hot Lap. You will then need to scroll through them and manually add them up to get your actual lap time; the Hot Lap won't do that for you.

Thanks, Kris, but I think I understand. My thought was that since the club already has the lap times covered, might we not consider using the Hot Laps for just sector times.

Don,

You could certainly set up the hot lap on the drivers side and do your own sectors if you have the beacons or check if the club has extras you could use on the other side without messing up the hot laps of those who just want a lap time all day regardless of timing errors.

Hey Jad, that's a good thought.

I hear Gary B. is the resident expert on the Hot Lap beacon setup. I'll have to check with him and get his feedback on something like that...

I know the hot lap is our AX & TT standard but it reminds me of an old toaster. Would anyone consider moving to ultralap? About the same money and the unit is smaller, has more memory, does split times, has download capability and a bunch of other features. My hotlap is on its last legs and would like to move to something better.

Hey Pete, the Ultralap is definitely a step up from the Hot Lap, addresses my issue and in a similar price range. However, with the number of Hot Lap units in use by club memebers, I would think the Ultralap would have to co-exist for a while.

I wonder if there is any conflict in the systems that would prevent them from co-existing on the same course/track effectively?

That's a good question. I'd rather buy the Ultra Lap vs. Hot Lap counter if they are compatible. Anyone know for sure?
