How do I get a shift light on iOS?

[Liquidsmoke]

I've seen the feature mentioned in your website area in the new version information page. I have upgraded to v3.0 and I still can't find where to get a shift light or suggested gear info.

[John@PPE]

You'll need to download the dashboard for it. It comes default in our Windows version, but for the iOS version you'll need to download it. I believe this is the correct one. http://www.dashxl.net/dashboard.php?dashboard=81

Just choose the download from DashXL.net option from the settings.

Ah great - many thanks. I'll give it a try! Btw I think it might be a sensible idea to give shifting dash as standard on iOS. I mean the chance of someone using thier laptop as a shift indicator whilst driving I think is slim. Whereas an iPhone can sit happily in a cradle in field of vision.

I downloaded the proper template but I am having difficulties in setting the proper parameters to make this work on a 2004 Mazda 3s. Can you help me figure out what should I use as parameters to make the feature usable?

Assume these are the specs available to me:

Final Drive Ratios
===========
1st : 3.307
2nd: 1.842
3rd: 1.310
4th: 0.970
5th: 0.755
Final Drive Ratio: 4.105

I multiplied each speed by the final drive ratio below and used them separated by semi-colons:

(3.307 x 4.105);(1.842 x 4.105);....

Wheel Circumference
=============

My car has 16" tires (P205/55/R16) so I used 16"

Minimum Engine Speed
==============

I could not find this info anywhere. I used 700 rpm as I think that is the minimum speed when idle. Or what would it be?

Maximum Engine Speed
==============

I found that my car can do 160 HP @ 6500 rpm so used 6500 rpm

The wheel circumference will actually be the distance around the wheel. Not the diameter. It looks like you are using the diameter.

Try starting with that fix and let's see where it gets you.

Thank you! So you mean I should use the perimeter measurement? Considering circle area A=pi*rˆ2 then the perimeter would be 2*pi*r = 2*8*3.1415 = 50.264

Is this a number that makes sense to you? Will try that later today and report any improvements...

[John@PPE]

It is the perimeter. That number could be right, but obviously I can't verify it without measuring your tire myself.

The "wheel circumference" setting is actually tire circumference, it has nothing to do with the wheels themselves. Personally, I leave the wheel circumference blank, and fill in the tire size specification instead (DashCommand calculates the circumference from the tire size).

Thank you. I had both measurements in place as shown below but later today I will try to erase the one for the Wheel circumference and report my findings again.

After these updates, now the Gear Shift Screen shows some movement so I guess that is progress. However, this screen does not seem to reflect the reality (it looks as if the gears had random movements like in the demo mode) so I believe I still need help validating my parameters. Can anyone look at my car specs from Mazda and tell me if any of the information I fed to DashCommand was incorrect?

This is the info I fed to DashCommand:

Wheel Circumference: 50.264 in
Tire Size Spec: 205/55/R16
Final Drive Ratios: 13.60;7.56;5.38;3.99;3.12
Minimum engine Speed: 700 rpm (its my guesstimate)
Maximum engine speed: 6500 rpm
Engine Displacement: 2260 cc

Here are my car specs (I own a Mazda 3s Manual Transmission):

I would guess that its going to get a lot more accurate after you remove the wheel circumference setting. Judging from your tire size, your tire circumference should around 78.156, instead of 50.

I did remove the wheel circumference param but it did not make any improvement.

I will try 78.156 as you recommended but please explain how did you arrive to it? I arrived to 50.254 by using the formula: P = D*Pi = 16*3.1415 = 50.264

[Weston@PPE]

Thats correct for the circumference of the wheel itself, but you also need to include the tire. Its the distance around the entire outside edge of the tire, not the edge of your 16" wheels.

You could, by hand, take the 205mm width, the 55% sidewall height, and the 16" wheel to calculate a diameter for your tire. Its not hard, more just annoying to do by hand. If you leave wheel circumference blank, it should do a calculation like this. It would go something like 16 + (205 * 0.55) = tire diameter. Of course, you'd need to convert the 205mm into inches first. After you've got a tire diameter you could do your same formula you posted above, except with the tire diameter instead of the wheel diameter,

A came to that number (78.156) by looking up an online calculate that does all the footwork for me. Specifically, I used this one here (it was the first one that showed up in Google):

Let us know how it goes.

Thank you for the detailed explanation. I believe the value 78.156 works as intended. At least I can now see how may actual shifting position matches (most of the time) the white circled number in  DC. I honestly don't know how this tool works from this point forward. Please look at the attached pictures of shift and rpm snapshots in the same timespan. I thought the blue circle was supposed to point to the next speed I had to shift to. Given my low RPM I actually did not need to shift to that position... I think I don't understand the tool or maybe my parameters still need additional tweaking. Can you please give me a URL or some guidance as far as how to use this tool?

[Weston@PPE]

The blue circle is the "suggested" gear. Its usually just the highest gear you can be in without going under the minimum engine speed setting. You have your min engine speed set at 700rpm, which sounds pretty low to me.

Your minimum engine speed should be set to the lowest rpm you are comfortable driving at while in gear. I've got a V8 car and I have mine set to 1050, a smaller engine with less cylinders would want this higher. It depends on your personal feel really, but I'd think a 6-cyl could be like 1100-1200, and a 4-cyl be more like 1200-1500. Its more about your engine specifically and your personal feel for when you want to shift.

Try moving your min engine speed up to 1100 or so and see if that works any better.

I tried 1100 and also 1300. The 1100 value seemed to improve but I am under the impression that 1300 made things worse. I also used a new skin (Tuxedo Mobile Portrait_TEST) to make things easier when capturing the shifting positions along with the RPMs. Can I trust the output it generates? Please see attached picture using 1100. While at it, can you let me know if there is a way to show the Coolant?
