Still a noob to the MyCal device.....

Recommended Posts

Well, now that the LMS CAD #2 is behind us.....

 

My travels back home from MI. and my most recent Official Photo Shoot at the FMC CAP has also been completed.....

 

I had enough time to sit back today, take a breath, and realize I'm quite the noob on this new MyCal Tuning Device.

 

Maybe it was that extra hour of sleep due to the seasonally adjusted daylight savings time taking effect :noidea:

 

But, any immediate suggestions any of you can offer up for me?

 

I'm most interested in utilizing the 1/4mile drag feature(s) first and then proceeding from there.

 

Any suggestions appreciated.

 

Thanks :tea:

Mike, check down a couple of threads, Chris has done a writeup on the 1/4 thing. As for the rest...I really havent spent that much time on the MyCal. My plan is to spend some more time on it this winter but has taken second fiddle to some other stuff

Yes Chris did a small how-to... But there is so much to learn!

I wanted to know how to use it for 0-60 and 1/4 mile too. However, I tried it this afternoon at the track and numbers don't match... It gave me a 1/4 mile of 12.60 while all my runs today were between 12.11 and 12.20... So, it read almost half a second slower!

I did my 0-60 and it gave me 4.07 sec. With a roll it is supposed to be in the 3.6's, so I would have expected about 3.8's... But it is nevertheless an interesting machine and I really want to learn more about it too...

Maybe the MyCal is correct and your track timer is off...that would explain alot?

 

And make more sense!! ?

Bwahahahahahaha :boink:

 

Now that's freak'n funny :thumb:

 

Maybe there was a reason why Steve didn't make it down for LMS's 2nd CAD recently.....

 

Cuz he knew he couldn't fudge the timing system & that even I may have had a chance to beat him :noidea:

But seriously, I know Napierville dragway is a fast track and well prepped. But I validated my times under similar conditions in 4 different tracks in Quebec and all within 0.1 sec. Please guys try a 0-60 with mycal and report... I tried it yesterday while snowing/ raining and 40F with my summer tires and did a 4.19 sec. Today I tried 5 times and always between 4.07 and 4.15 sec. I'd be curious to compare.

Unless at the track, it is difficult ro test a 1/4 mile safely.

Cheers!

Mike I set yours all up I thought, but in case I didn't I will email what I sent steve.

My G-Tech and MyCal are pretty darn close....for whatever that is worth....

 

Broke the 4.5 second 0-60 barrier on all season tires after installing the CAI. Only other mod is a LMS 4+.

I presume that you have mycal as well if you stated that they are close. I don t know if g tech connects in obd2 like mycal, but I d like to see a simultaneous run using both device...

 

I know that with the iphone with the app dynolicious, the accuracy was function of iphone calibration and stability. The more stable, the lower were the numbers.

I haven t mounted my mycal yet and left it in the cup holder loose while doing the tests...

 

TSS: if you could try both at same time and report that d be great

Thanks!

The G-tech does not connect to OBD II - it mounts on the windshield.

 

I admittedly have not run them side by side simultaneously. I have run them one after another. Four runs, two each with some resting time in between.

 

The reason I never thought to do simultaneous (though that makes a lot of sense - duh me.....) was that the G-Tech does not require skill/reaction time (which is why I like it). You start whenever you want from a stop and it senses you starting, versus the light tree on the MyCal. So even if I run them side by side, my reaction time (for the MyCal) will still be a variable. With all that said, the difference in side by side runs was very very small. Close enough for me, as I am not a track guy and will never make the top 10 here. My mods are done and I am happy with my current set up for a DD. :)

 

I think the bottom line is that the MyCal seems pretty accurate OR both the MyCal and G-tech are off..... LOL.

As a numbers guy, do you have any feel for what a tenth of a second improvement in 0 to 60, would translate to in quarter mile numbers?

Hmmmm....more people stating that the MyCal is accurate...Steve' date=' your claims are getting more and more fishy!! Lol[/quote']

 

Poor me! I would think then that the methods are different to calculate between track and gps devices. At the track, there is a rollout and not with mycal... Just that is 0.2 sec. The ET on mycal showed 12.60 at 114.6 mph while my run was 12.19 at 115.8mph. So the trap speed is closer. On the gps it is an exact number at a specific time; at the track it is an extrapolation of the speed when calculating the elapsed time in the last 60 ft of the 1/4 mile... That could explain the difference...

As long as mycal is steady (which seems to be), it is a good indicator/tool to monitor a car... But I believe that any track numbers will always show faster and quicker numbers.

So, when you read in a magazine that a car does 0-60 in 5 sec, it is usually based on a gps device, so we can comparee our car using mycal... But when reading a quarter mile stat, they take it from the track numbers... So, we should do the same. That said, my 12.09 at almost 118 mph is done in optimal conditions which is rarely the case when a magazine tests a car... But I always ran between 12.09 and 12.34 since I have stage 5 with mycal, with temperatures up until 70F...

Cheers!

It is not a straight line, but in general, for AWD cars that run between 12 and 15 sec, 0.1 sec of 0-60 is about 0.1 sec in quarter mile ET.

Rule of thumb: 0-60 in 4 s = 1/4 in 12.3 sec at 112 mph

5 s = 13 sec at 107mph

6 s = 14 sec at 100 mph

7 sec = 15 sec at 93 mph

 

More or less, but gives you an idea... (slower if calculated with mycal lol)

As much as we all collectively, and individually razz Steve about his "numbers"....

 

I personally find it amazing and it certainly always provides the backdrop for interesting reads, and resulting discussion(s) / topic(s) accordingly.

 

For the record Steve, thanks for that :hail:

 

Kind of makes me wonder why you never starred in any of these episodes, or even had a leading role :noidea:

I am going side with Steve on this one for one simple fact. Mycal also shows when doing 0-60 distance travelled in feet. And the only signal it uses to come with this is vehicle speed sensor, but one think the only truly accurate way to determine distance traveled would to input a tire size. I have yet to stop watch my car and compare to Mycal, and I know there is a lot of things that can be done with Mycal and adjusting parameters and values there maybe a spot in there to input a tire diameter.

I am replying to my own post, but to complete the above estimation... I was on the internet and while navigating, I found a porn site... oups, wrong forum, I found a forum in which another number guy (I am not alone) had a rule of thumb too:

 

For cars that run between 11.5 and 14.5 sec 1/4 mile, substract 8.5 seconds and you will get an idea of the 0-60 at the track. I would add to that a 0.2 seconds because at the track you have a rolling start. So is conclusions were in line with my estimations... just a bit more optimistic ( I arrived at 0.5 seconds more for 0-60)...

 

So, Darrell, my numbers may not be too fishy after all... lol!
