Another FYI, the 0-60 timer on GM products rounds down, not up. So a 3.95 becomes a 3.9 not 4.0...

If you really want to time yourself with absolute certainty, get a VBOX or go to the drag strip.

A couple points
1- anyone with a manual transmission that has used the timer will vouch it starts at even the slightest movement regardless of if you even have your foot on the gas.
2- you are very right that if you shift hard and get a lot of wheel spin you will trick the car into thinking it is going faster than it is. If you spin hard in 1St u can shift early into second and get low 3s.
But as you can see in the videos there is not enough spin for that to happen and the car is fully engage in second before the timer stops.
3- in one video you see me move a little and then reset because I didn't have the timer set.

Watch your videos again closely at when the timer starts (~4-5mph). Also, on the one I watched you got wheelspin on the 1-2 shift and speed shot up... that is not real.

That seems improbable for objects that are rapidly accelerating. They would have to be running a refresh rate that is astronomically high (military grade processing) and the PDOP will be all over the place.

I'll check them out though. The level of precision that is available to civilians has really improved in the last 5 years.

Speed shot up, timer did not stop. Had the timer stopped I would not had needed to continue in second gear.
Significant wheel spin? Are you watching with the sound on? You can hear a small chirp.
If you are shifting the camaro quickly you get no more than a chirp.

As for the vbox, way to expensive.

I don't believe your 3.6 achievement(s) was/are accurate.

maybe the timers off or you're somehow throwing it off with wheel spin or maybe your driving down hill to achieve it idk.. but I'd bet money if the M6 could accurately pull 3.6 Chevy would not have it rated at what it is.

low psi in your tires or the 315s whatever. I doubt your getting to 60 faster that ats-v's and hellcats accurately OR stingrays

lol driving downhill......

That's absurdly cheap for claiming accuracy to the hundredth. At relatively low rates of acceleration it's probably pretty accurate though.

It's expensive for a reason, its much better than your in dash "toy." These are the types of tools that the "bad magazine drivers" use for an accurate measurement for all vehicles. This is why their times are "worse". Sure i believe with thousands of owners in many different conditions some owner will get a couple tenths faster. I will never believe you are getting a 3.6 - 3.9sec in a bone stock manual until someone posts a GPS confirmed time.

Are you guys telling me that at the drag strip your official time is NOT measured by the car breaking a beam of light? (feel free to laugh at my ignorance)

[SpookShow'84]

The VBOX is at 95% accuracy for a 3 meter solution, with a claimed 1% variation on acceleration with a 10Hz refresh rate.

Depending on how the software is written for the 0-60 timer its going to be pretty damn close unless your talking about fuel car levels of acceleration. It's going to work well enough that the driver will not have to question the result. It will not be the most accurate that is possible, but 1% is damn good for civilian channel GPS.

Your right. They use a beam of light. It's the most accurate way to time, there is less information to process and the speed of light leaves little for interpretation.

Its more about the fact that the VBOX is actually measuring the 0-60mph of your vehicle as a whole. Your in dash timer is measuring how fast your tires are going 0-60mph. If you use the 0-100mph feature i bet they are pretty close to spot on since you have no chance of spinning at 100mph.

Would you like to ask me if I care what you believe?

Id do a few 0-100s but think it is irresponsible to do 100 on side streets. Just my personal opinion.
