Bad MPH conversion

Okay, will keep an eye out when you can update those codes.

Regarding the MPH, not in agreement, going faster than 8 mph, given the same car ran on a commercial track 1/8 mile, i clocked in at 34 mile per hour....anyway, will see what tweaks you can do.

The Drag racing community appreciate the effort and the steps you outlined above to get this to work...Thanks Again.

Hi Guy,

Is there an estimate  time when you can update the codes  ?                                                                    

I made a little update (version 5.48g), you can download it here

Can you try it with scale 1/1 ?

Hi Guy,

Not sure what specifically i am checking, but :

1) Was able to download to version 5.48g, no issue.

2) only one set of data recording, lane 1, ( while running 2 cars ) .

3) SETTING SCALE   1/1 ,  Distance 13 feet, converted to 3.96 meter.

4) cant get the " # of segment " to " 0 , " when I try to change it, default back to 2, see the message below and the  set up pics.

see attached settings, let me know it ok, was playing with different settings, same results.

If a user can point me to the thread to enlarge the data on the screen, cant seem to have it fill up the entire screen screen.

The main issue what I am seeing is the the data on the DS 200 is not synching with the program.



for example

RT + time down the track = ET

from the DS 200 showing

0.300 + 0.827 = 1.127


PC LAp counter showing


0.220 @ 16.97 mph


so mix data and not making any sense.

settings at 20 meter, scale 1/1 .... data a lot closer to the DS 200



DS 200 data


0.435 + 0.950 = 1.3850 sec




PC Lap

1.3290 sec @ 33.66



I think that mileage is similar to me running it at a commercial track and the data is close to the DS....

still not making sense given my track lenth 13 feet ( 3.9 meter) , and this run was at 20 meters.


Any input would be helpful ..... thanks.

In fact  in version 5.48g i made a lilttle modification in the MPH conversion, normally the mph should be ok (at least in scale 1:1)
At this moment i didn't made other modification, PC Lap counter still only capture the track time, not the reaction time + time down track = ET.
PS:
I have  started a new topic to not to pollute the initial subject of the post which was "setup drag race".

Got it about only track time ; but I am asking if the set up pics are correct and that the MPH calculations are not in synch with the DS 200 box  ?


What other settings you want me to try ; etc .?

Hello,

About the sync with the DS 200 box: Pc Lap COunter should display the same lap time as the DS 200 but maybe you have unticked the option "Get laptime from DS lap counter" , can you check ?




Also, can you check the message part of Pc Lap Counter main screen and also the message part in DS 200 interface of Pc Lap Counter, maybe you will find some messages like  "bad lap time" or other message , will be nice to take screenshots.
(if you don't know where is the message part then look here http://www.pclapcounter.be/graphical_interface.html)

Hi Guy,

See pics, box checked. Also, I am not really following why the MPH is off if we have the length of the track, the time traveled and we equate it to a scale, we should be able to come up with a speed/MHP ?

Hello,

Thank you for the screenshots, at this moment i will focus myself on the sync issue and not on the MPH calculation.
According to your screenshot the option "Get Laptime from DS lap counter" is ticked and so Pc Lap Counter should you display the same lap time as the DS lap counter but you said that's not the case.
On my side i have a DS300, so i will plan a test with my DS300 , i will setup a drag race in Pc Lap Counter like you and i will see what happen.
Hope to make the test this weekend, i will let you know.

Regards.

Guy

Sorry this weekend i couldn't made the test because I didn't find my Rs232 usb cable but finally today I found it.
Hope to make the test next weekend.
By the way; how did you setup your ds200 ?, did setup your ds to make 2 laps ? Did you setup min lap time? , did you setup other things on your ds ?

Hello,

i made a test with my DS300, here the result:

Drag race , track 4 meters , display speed , convert to mph, scale 1/32 (track setttings: min lap time=0 , options screen: reject lap less than = 0)



Lap time on the DS 300


as you can see lap time is the same as the DS300 and i think the MPH is correct, can you confirm ?
as you can also see at this moment the time on track is not the lap time + reaction time , this will be for another version.

PS:
I had the case where the reaction time was 59,000

.

Why 59,000 ? should be a bug somewhere, i have to check because i didn't had the problem after restarted PCLC

Hey Guy,

Regarding your reaction time, right 59,000 should tell you something is way off !

Regarding the test on your tweaks

1 first run, it synched up with the DS 200, time down the track :

2nd Run, made no sense !

ET= reaction time + time down the track       :        yet you told me PC Lap can't calculate  reaction time, yet it included it .


ET = 0.304    +   0949   =    1.253   ( showing on the DS 200 pro ET time, same number now showed in PC LAP  1.25



Plus look at the MHP, still dont think that is correct !


We need consistence in both systems to feel confidence about this data !

It's like the problem occur at the second run.
I didn't test second run, I will make the test.

I need more information to help you:
- Did you setup your ds 200 to make 2 laps or 9999 laps or other ?
- How do you start the race : did you start the race on your DS by using the "start button" of the DS or you start the race on Pc Lap Counter ?
- How do you start the second heat: did you the start the second heat on your DS by using the "pause" button, or you use the restart button in Pc Lap Counter ? or other way ?
- before starting the second heat of a drag race you have to click on the button "Rotat" in Pc Lap COunter , did you did it ?

Regards.
Guy
