Currently my transponder is mounted on the inside of my right front frame rail and has been working just fine in that location. But now that I'm adding aero to the car and an undertray, just wondering where some of you guys have been mounting your transponder as my undertray will be blocking it in that position. I don't want to move it too far back either. Thanks.

I recommend mounting it on the back bumper.

JiminVirginia

Yep. Works great. A couple of zip ties and you're set.

I better watch it... one of you C5 Mafia guys might just take it off and duct tape it on the rear bumper

I put mine on the side of the sway bar bracket for the rear of the undertray .... (It may pick up through the undertray, if it will go through the floorboard of our cars- But I have not tried it) plus its easy to get too with the right front wheel off. This is right before I mounted the transponder...

I have mine right behind my front undertray, but I don't drive a vette so that really doesn't help you..... I wouldn't put it at the rear just because that is how you are timed. If you have a really close race it's always better to have that as far forward as possible. Then again it might not come down to a nose length like NASCAR so feel free to do whatever just my $.02.

Remove one of the rear fender inner liners and screw it to the back bumper then they can't take it....

It doesnt matter where it is mounted because it will be in the same place every time it records a lap. Having it in the front or back wont affect lap times. Even in a race it shouldnt matter because there will always be a visual of who crosses the line first.

drivinhard

For TT you are right, but I don't think they would overturn T&S data for a visual, and that's assuming for sure somebody would have a picture.

In time trials, that's true.



That might be how it's supposed to be, but in reality it doesn't always happen.

I lost a position and bragging rights to a friend of mine who had his xponder on the front bumper and mine is affixed behind the front wheel in the space where the ECM is.

We had raced hard with each other for 1/2 an hour, but I crossed the line before him, and he and I both knew it. We laughed about it after the race about how I beat him by just a fender. Then the time sheets came out a little while later; I was scored behind him. I hollered, but T&S said they can't possibly view every one coming across the line so they have to let xponders be the judge.

The chances of being that close at the end are extremely small, but it can happen.

I learned my lesson about eliminating as many possibilities as I can that can let me lose a race.

Put it as far forward as you can safely and legally put it.

**** I was writing when Mark was posting. But we said the same thing.

Kubs

I stand corrected. I am moving mine to the front license plate now.

I have mine in the location Jody mentioned... made it easy to run the wire into the passenger side footwell and pick up the spare pigtail to get switched 12V power.

rasrboy

Or better yet, they may mount it behind theirs.

Damn Mafia guys I tell ya.

If this was an SCCA event, T&S was derelict in their duties. The GCR (i.e. "the rules") require that finishes be visually observed...no wiggle room there. Starters and T&S should be keeping a lap chart.

If T&S claimed no visual observation, you had a perfectly valid protest, and should have exercised your rights to get the results corrected.

Maybe it wasn't a big deal to you or your friend....fair enough...BUT if T&S is simply taking "transponder passings" as final results in RACES THAT MATTER, then this is an issue that needs to be corrected.

If something like this happens again, at very least talk to the Chief Steward or one of the Asst. Chief Stewards.

It was the "other" group.

I haven't seen anything in their CCR specifying anything but transponders.

Thankfully, my buddy and I were in different classes and all that was at stake was bragging rights, and beer.

geerookie

I bet you didn't realize mounting it that close to the PCM can cause interference in the transponder and it can report your time incorrectly.
Those Mafia guys have got all the tricks down and they have figured out how to make the PCM "adjust" your lap times when it is mounted there

travisnd

How else would I set any track records

Serioulsy though... are you serious about any issues? I've had it mounted there for going on 2 years w/o issue.
