Is this possible?

How can you trust drag times calculations when you get bs numbers like this... my car ran a 12.4@111 with a 4.5 0-60 verified by my log... makes no sense how someone else smokes me by .6 0-60 but loses the race by .2... I'm calling bs on drag times

I don't trust your 4.5 result.  Are you saying that is the result you see from your logs?  If your car will run the quarter in 12.4, your 0-60 should be quicker than 4.5. For example, based on a road test in C&D, a Mustang GT does 0-60 in 4.4 and runs the quarter in 13.0.  I know damn well a tuned SHO will smoke a Mustang from 0-60.  I have raced plenty of them and always walk away from them on the low end.  They start gaining at about the 1/8 but can't quite catch me at the end of the quarter.

Where does the data come from that is on your log?  Does it obain the speed from the car's ecu?  I am not trying to be argumentative here but something is causing the 0-60 time you are seeing to be slow.  What is your 1/8 mile time and speed?  I think the drag times calculator is pretty accurate and will likely show your 0-60 under 4 seconds.

Yes from ecu, I take the time at 0 miles per hour right before the car moves, then take the time at 60mph and subtract them... I don't know how much more accurate you can get.stock tire size and flower rims.

The log from this run is where I got the 4.5

Just out of curiosity was the data wired or wifi/Bluetooth? A bit of lag is expected in a wireless setup. There are lots of examples here and out there of SHOs doing 0-60 in 4 or less.

Mind posting the log f8tl? Here's mine from tonight that produced a 4.5sec 0-60 . . @ ~6000ft DA.
also, this site is rumored to be the most accurate for calculating 0-60 times from 1/8th times/traps. i would trust it must more than drag times calculator
http://www.wallaceracing.com/0-60_equation.php
although when i put in my time slip info it tells me 4.6 and the log  from the same run tells me 5.0sec. . then again the site doesn't compensate for altitude so i'm sure that's a factor.

Don't forget to calculate driver weight and anything else that maybe in the car

Add at least 200 lbs + then.... even slower..

Yes I can post my log when I get to my computer, that site says 3.8 for my 0-60... which for sure I like that number better than 4.5, but I still think log info is going to be more accurate.

YES!!  I originally said the Drag Times calculator but I meant the Wallaceracing calculator!  That is the one that has been consistent with the Aeroforce gauge or simply making a video of a 0-60 run and using a stopwatch to measure it.

i attached both the full log a one i cut out everything other than the relevant info.

I am pretty sure your computer's clock is accurate, so the way you calculated your 0-60 should be perfect.  That is what I was doing.  Are you logging to a PC or directly to X4?

Okay, Wallace shows 5.18 0-60 for me and I got 5.51 from my log.  This was my 13.81 @ 98.24mph.  I think the head start you get at the track before you trip the beams makes a big difference.  The log will show longer to your trap speed than your slip as well.  Just going from a shallow stage to a deep stage is worth over a tenth in the 60ft.

Brucelinc's mks did 3.9s all day, based on the Aeroforce gauge.

As does my MKS (same year and tune as Bruce).  3.94 actually per my Aeroforce.  3.92 per my G-Tech.  No mods other than "4X Plus" 3 Bar tune with the soft 1-2 shift modification.

 

[bamsho]

The only issue using Aeroforce for times, is that if there any tire spin, that comes into play.  I did couple passes at the track usinh mine.  It was showing times, before I crossed the end of the traps.  Was about tenth or better off.

Something to keep in mind is LMS does boost mapping.  They are *likely* playing with the wastegate to keep pressures higher than normal... and they also can control a great deal of the shifting behaviors versus SCT's limited interaction with the PTU's.  this can account for quite a bit of gained time 1/4 mile in the 1st half of the track...

After that 1/8th things normalize out from a number of youtube vids and then 'same/similar power' but lighter sports cars start pulling us in,  on a 1/2 mile track we'd lose a bit more than we currently win with regard to SHO vs stock v8 2015+ stangs and very similar sport car weight/power profiles.

What do you mean interaction with the ptu? The ptu is strictly mechanical isn't it?
