New ratio calculator tool

[ashtrans]

Hi all,

we have had some software written for our web site which allows you to put in your gearbox, transfer case, diff and tyre data and it works out the engine revs at a given speed,

Ideal for working out what transfer case or ring and pinion to change to with different tyres etc.

hope you like it :

Series Gearbox didn't fill the ratios in

Opps, working on it now

[Bowie69]

That's a handy tool, well done!

I could only get it to work in IE though, FF and Opera the fields didn't fill in properly, some sort of JS error I guess, though nothing in Firebug?... Didn't even get an option to select a gearbox type.

[Ruuman]

works great in chrome, brilliant tool

[FridgeFreezer]

Not working for me, falls at the first hurdle - no gearboxes in the drop down box

(Using Firefox here)

[V8 Freak]

Worked well in IE.....

Shows I really need to go 1.2 ratio in my transfer box...... Great tool, nice and simple for the likes of me !

2600rpm @ 70 on the V8, think the 1.4 ratio LT230 has got it just about right for on-road speeds, for off-road, there is always the brakes :)

It would appear that it doesn't like firefox, but it works ok in IE. shame....

Using Firefox 3.6.8 on OpenSuse 11.3 the drop downs for gearbox etc. are empty.

I'm sure you've sussed now, Dave, that it doesn't work in Firefox. Drop down boxes are empty.

Chrome works perfectly

[Gremlin]

Great, i had it on a spread sheet.

I will ask our IT guys to try and get it working with Firefox,

[bobtail84]

What a useful tool. Mind you with the 1:003 hanging from the back of the LT77 1830rpm is no surprise at 60mph and that's with 4.11 in the diffs

A very useful tool.

Could you add data for the Borg Warner transfer box?

[simonr]

Didn't seem to work for me in Firefox or IE v7. It's surprising as the page is written in PHP so shouldn't suffer from browser compatibility issues as the bulk of the work is done on the server and it just sends HTML to the browser.

Let me know if I can help at all.

Si - if you view source, the page is using Java. I think the php aspect is just the content-management side of things.

Makes no difference - if the PHP is generating incompatible HTML code, it's still incompatible HTML code.

if you view source, the page is using Java

Or even JavaScript

If I get time later I'll have a look through and see why the JavaScript isn't working on FF. No charge

[FridgeFreezer]

Or even JavaScript

Java, Javascript, Ajax... it's all high-level nonsense of some sort or other as the boss says, proper programming is done with 8 toggle switches and a "STORE" button

Shame they didn't just do it in PHP as it would be easy peasy and work on everything.

........, proper programming is done with 8 toggle switches and a "STORE" button

There seem to be quite a few errors in the JS bit, mostly by not using proper DOM methods for constructing elements.

And, honestly, the population of the gearbox drop-down menu has no business being done by JS, do it in PHP. That the others are done in JS, I can understand, because they're dependent on the first selection.

I'll fix it in exchange for a rear ARB

I agree

I didn't look at the source - I just assumed it would be written as I would do it with the lists being populated by the PHP / ASP. I'm not convinced that the list needs to be populated by the code at all - it's effectively a static list, so just embed the list content in the HTM.

A programming conversation on LR4x4, oh my

I agree with Si, I would be hard-coding in the contents of the first box via HTML and then using a PHP script to do the working out. Would require another page load, unless you AJAX-ed it, but I prefer PHP to Javascript

[landroversforever]

I do like a good geeky conversation
