Odd fuel usage

Mios 4Me · 01-08-20, 11:43 PM

I topped off the tanks at Tulagi en route to the Bungo Suido on an insertion mission, reaching that destination with ~62% remaining, IIRC. At a position 300km 152 degrees SSE of Miyazaki, I had 52% remaining, so I set course for Exmouth Gulf via the San Bernardino and Makassar Straits. I was under 10% before I reached the first strait.

Going back to that same save point (52%), I instead set a course directly for Tulagi and avoided all combat. Nevertheless I was under 10% just 150km SSE of Guam. Only a little over 200 km NNW I had hit the 25% warning.

All speed settings after the 52% mark were at 2/3s impulse (this is all in stock 1.5). What's going on? Does the game model the Kuroshio and other currents or is this a fault of mine or a program glitch? I can't imagine why COMSUBPAC would send us on a mission of no return.

Yer gas gauge is broken, and a 3/4 tank is actually at half...

But seriously, how fast are you going? Generally speaking, Ahead Standard is the most efficient, though not always. Does Stock have a "Range at Current Speed" menu button?

Based on earlier observations, standard cruise speed in stock 1.5 is Ahead Slow, not Standard. That's what I used exclusively from the save point with 52% diesel onward. I didn't notice the button you mention in this test series, but have seen it on GFO and Berbster's mod.

Generally speaking, most of the SH4 fleet boats have a range of 10,000 to 11,000 nautical miles if you're conservative. The S-class boats are probably around 8,000 nm. This also depends on Stock game vs. whatever mod you might be using.

You'll burn more diesel at 1/3, 2/3 (Slow), Full, Flank and when you're recharging batteries at all speeds.

The most conservative speed for the fleet boat is going to be around 10 nm/hr and the S-class around 8 nm/hr. This is around "Standard" speed but it's better to actually dial in your exact speed on the dial. It would be advisable to try some speeds; 8, 9, 10 & 11 nm/hr and request the "Range" at these speeds and you'll quickly learn the most conservative traveling speed.

The maximum "Range" button is generally under the Navigator controls if memory serves me correctly. I've made this command an actual button on my keyboard; some of the mods have to.

Note: It should be obvious, but batteries recharge faster at slower speeds and recharging affects top end speed. There's a button and keystroke that toggles recharging that may not be available on the stock game.

Hope this is helpful.

The only related button in Navigation is the "Time to End Course" in stock 1.5, unfortunately. I'm using a Gato-class boat for testing manual targeting and limited fuel before moving on to FotRSUE and all the customization that will entail, so I guess this only means something if the supermod follows stock's lead in this regard. Still, it's very odd and now I remember why I chose unlimited fuel and automatic targeting very soon after I started playing this game.

Stock game doesn't have a range to end button for fuel. You can patch the files to get that info. <shift-g> for fuel range, <ctrl-w> for weather.

the info:
Fuel range at current speed:
So, in: \Data\Cfg\Commands.cfg
Commands.cfg (open with a text editor like Notepad)

[Cmd257] <------------------ Step #1: Find "[Cmd257]"
Name=Report_time_to_turn
Ctxt=1
MnID=0x3F250002
Key0=0x47,s,"Shift+G" <--------- Step #2: Add this string

----------------------------------------------------------------------
If you also want the 'Weather Report' "Ctrl+W" make this [Cmd261] edit:

[Cmd261]
Name=Report_weather
Ctxt=1
MnID=0x3F250006
Key0=0x57,c,"Ctrl+W" <--------- Step #3: Add this string

----------------------------------------------------------------------
To remember "Shift+G" and "Ctrl+W" add them to your in-Game F1 Help file:
In: Data\Menu\Help\Help.cfg
Help.cfg (open with a text editor like Notepad, and find the 'OTHER CONTROLS' section:

[Chapter1.Phrase6]
Phrase=OTHER CONTROLS| NumPad - Decrease Time Compression| NumPad + Increase Time Compression| Backspace Pause|

------------------------------- Step #4: and add Ctrl+W & Shift+G:

[Chapter1.Phrase6]
Phrase=OTHER CONTROLS| Ctrl+W Weather Report| Shift+G Maximum range at current speed| NumPad - Decrease Time Compression| NumPad + Increase Time Compression| Backspace Pause|

Unfortunately, there are a number of commands that have been left out of Stock SH4 or totally ignored as keystrokes.

You'll be able to check your gas mileage when you install FotRS UE. "CTRL+G" is the keystroke for "Range to Course End" and "K" is for "Maximum Range at Current Speed" per the support documentation that accompanies the FotRS UE mod.

I've personally added and/or changed many keystroke commands since the early days of playing SH3, and then SH4 to suit my own personal needs. Most all the super mods have to, but they vary per the individual mod.
