Still not great though. Too much wheel spin/possibly bad tires is my assessment.
However, onward through the fog!....we keep trying...

Znod - thanks. I agree with you - wheel spin / tires :thumbsdown:

The only place I have ever seen the phrase was at Oat Willie's in Austin.

You are correct...Oat Willie's was a head shop in Austin, TX, and his slogan/battle cry was "Onward through the fog!"

You are due for both weather and altitude correction improvements. Things should look at least somewhat better after making these adjustments. Unfortunately, the available adustment calculators don't work well for anythng but 1/4 results. I will use your data and get some approximate results for you--as mentioned before. It's 3 a.m. right now so I am going back to bed soon.
Still, even your first 1/8 mile speed looks too low. I think my GT2 reads low for 1/8 speeds, but who knows?

I have been trying to research weather correction info on cars equiped with computer controled engine management systems.These systems are constantly adjusting fuel/air ratio,timing according to atmospheric condiitions.I am wondering if the correction formula's used by NHRA are valid for these newer cars.I think these formula's were developed for cars with carburetors and no computers that cannot adjust to conditions.So far I have found nothing on the subject.I suspect that the factors may be different for the newer cars but I don't know for sure.Does anyone have any thoughts on this subject?
I just got a Wx notification on 25-34 knot winds so I am not sure I can even get to any baselining in today with my replacement Gtech meter before I get the dreaded (or hoped for) 20.01/2

Hello Guys,
Great thread!
Could it be possible for any of you also to calibrate the testers to 0 - 100 km/h,
that should be 0 - 62.1388 mph.
Since all acceleration measuring in Europe uses this and the 1/4 mile
it would be easier to compare possible EU results.

Below are the 0 to 62.14's that go with my best 1/4 mile results. They probably are my best unadjusted 0-62.14's, but I didn't search to find those in particular. Getting weather and altitude adjusted values takes a bit more doing. I'll be back to you on a new post.
5.470
5.540
5.545
5.555
5.558
5.541--Average
My similarly determined 0 to 60 unadjusted average is 5.145. So, on average, it takes me .396 secs to go the extra 2.14 MPH on an unadjusted basis.

5.300--Average
My similarly determined 0 to 60 adjusted average is 4.917. So, on average, it takes me .383 secs to go the extra 2.14 MPH on an adjusted basis.
Please note that one cannot get adjusted for weather and altitude results from the NHRA calculators for any values other than those for the 1/4. But, I found that I could regress all my unadjusted time/speed values on my unadjusted 1/4 time/speed values and use the resulting coefficients to obtain what look like extremely good estimates of other desired weather and altitude adjusted values--such as those above.

Since the air resistace will increase from 96.56 km/h (60 mph) to 100 km/h (62,14 mph)
quite a lot (relatively) the mathematics will not do as a straight axle.
Therefore, if possilbe, the measuring should actually be done by going all the way to actual
speed of 62,14 mph, for being accurate.
I'm still working on the stickshift, auto, SMG project overhere...
