what is the drag coeffient (cda) of a standard 996TT??

what is factory weight ??

I am getting ready to try out my AX-22 and I need to enter these!

You don't need to enter any of this information, it is irrelevant for measuring acceleration.
Just switch to the "continous" mode let it calibrate whilst stationary on a level surface (with good view of sky for GPS) then drive off as slow as you want.

The AX22 will measure your cars movements in terms of elapsed time and speed until you decide to save the data - so you can drive round for an hour or whatever and do the runs when its safe.

The analysis comes hwen you download the run, you can "zoom in" on the acceleration bits and simply read off elapsed time between whatever speeds you want.

For even more in depth analysis - send to Jean who can give chapter and verse on the run

BTW DO NOT use the "from" and "to" speeds feature, this is what has given silly timings for Alex/JJay, possibly to do with the inputs you mention above - this was certainly the case with the non GPS AP22 which proceeded the AX

thank You, I will give it a Rip!

I did 6 or 7 runs 60-130 mph and as soon as I figure out how to download data
on my work computer (my laptop doesnt have the right connection or cable), I will
email to Jean (where any BS will be sorted out) and he will share results.
Sorry, I am a bit of a Moron when it comes to computers-but I am learning.
BTW it was 74 degrees fahrenheit today for my runs, very nice weather .

You just need to buy a USB flash card reader from any store, insert the memory card you just recorded the data on in the reader, plug it in the USB port, and voila! Then save as "Marty60-130.RUN" or similar, and email to me. I will be happy to look at the data for you and share my thoughts with you first.

Man its freezing for you guys out there in the US, here I woke up at 4AM to try and get some 110F but no luck

Jean, I see that I need to buy a card reader and I will do so on tuesday latest.
and yes we actually had the hottest summer on record I believe, but of course it is relative,
we get excited when our Lake temps reach 80 degrees fahrenheit.

data within two days...
