Calcing 0-60 times and 1/4 mile times.

[SIKDMAX]

Went and did a bit of logging this morning with a new tune I blew in. I calculated my 0-60 times (not accounting for RT) by just watching the timer and when i clicked from 0-1 and 59-60. Now.. is there a way to log milage at all or some other way I can judge when 1/4 mile has been travelled to get a somewhat close 1/4 time?

Go to dashboard "B" on your log and if you have the VSS active you can look at the time of the log in the lower right hand corner at 0 mph and the again at 60 mph and see how long it took you to get there. I'm not really sure how accurate that would be, I would imagine that you will have to have the correct tire size dialed in at the very least.

Uhh.... thats what I said I did do :rofl:

Im looking to find out how to do 1/4 mile.

:sorry: Maybe pick a speed "say 98 mph" and see how much time has elapsed from 0 - 98 mph in your log, maybe the time would be say 13.4 seconds, now go look at the timeslips tab and see if 98 mph is a valid 13.4 sec. 1/4 mile time. This is in no way going to be real accurate, but it could give you a good idea

Or you could by a G-Tech :joker:

so how fast did you go 0-60.....................

Haha.... it was just a tow tune that was sort of weak (well, thought it was gonna be weak! ) and it spun thru 3rd, hit 122 mph *cough* closed down testing area of course *cough* and made some serious power!. I wasnt even thinking about 0-60 times when i was logging so I didnt do anything more than a 2wd hammer from a stop, no boosted launch or anything, but that was 6.294 seconds. I figure with some more tuning, 4x4 and some boost that could be decreased dramatically Oh ya - a visit to Mike L haha.

If you use mileage it will be off if you have any tire spin, since the tires have gone further than the truck

 

[SIKDMAX]

Correct.... wont have much of that in 4x4 hopefully... like I said wasnt really thinking about launching.

I feel like a dope :banging:, I never pay attention enough. Haha

 

[SIKDMAX]

Oh man that smiley is great! Going into the collection for sure hehe

You could do by exporting the data to Excel then accumulating distance. It won't work if you are spinning your tires though.

Time new - time old = seconds
Current MPH / 3600 = miles per second

Seconds * Miles per second = miles traveled.

When the sum gets to .250, you have travelled 1/4 mi, and subtract the first time from the last.

 

[SIKDMAX]

OK.... next question. Does anyone know of any "personal" 1/4 mile timers for sale? (not gtech or something like that) Not like a full track system, but something with a tree or just 2 beam sensors that you set 1/4 mile apart and it times. I have access to paved private strip, just some way to time it. Would be kinda cool to have my own personal 1/4 mile strip per se

 

[SIKDMAX]

Oh boy! http://www.portatree.com/

 

[serpa4]

One of the PIDs is a g-force meter. Could that be used in some way with the truck's weight, acceleration, and time to get a 1/4 mile time? That is what the G-tec uses.

 

[McRat]

Do a 1/4mi pass with datalogging on.

Record timestamp and MPH, and email it to me. I'd like to play with it.

 

[SIKDMAX]

Hehe sweet Pat. I have it physically marked out so ill do it close then email. Probably won't be till morning.

Oh boy! http://www.portatree.com/

Wow, I thought my friends and I were bad with our cars, stopping on roads and spraying VHT down and doing a few burnouts so that we could get some rubber down to hook...and yank the front tires on the street

I can only imagine setting up a tree in the middle of the road downtown LOL :driving:

You don't need to mark it. Just go 0-105mph and collect the data and I will show you how to turn it into a timeslip.

OK, we need to use millisecs instead of Timestamp, and KPH instead of MPH to get better resolution of data. Then we convert it afterwards.
